WEBINAR: Manage Your Infrastructure Easily and Cost-Effectively

Do you know the location of your infrastructure assets?

Do you know what needs inspected and when?

Do you know which assets are most critical and carry the highest risk to the community if they fail?

 

The answers to these questions are crucial to protecting the safety of people and property in your community.

You’re responsible for miles of infrastructure, and your job is to make sure it continues to function for the people you serve. Whether it be pipes and inlets, roadways, or bridges, you have to keep them performing at an acceptable level of service, and, more importantly, you must protect local residents and business from the consequences of failure.

This has always been a complex job, but new regulatory requirements, aging infrastructure, and tight municipal budgets make it even harder.

An asset management program can make it easier and more cost-effective, and this webinar will show you how.

Asset management is a proven methodology for determining where to best allocate your infrastructure dollars. It helps you cut through the questions and prioritize exactly what needs repaired or replaced. It can also help you effectively plan and mobilize the money to address those needs.

In this webinar, we’ll discuss:

  • What asset management is and how it works
  • What types of technology is available to assist with asset management and how to determine your particular needs
  • The many benefits of asset management for better targeting O&M dollars; providing justification for rates, fees or budget allocations; addressing government reporting requirements; and communicating with the public.

How One Town Overcame Barriers to Address Aging Infrastructure and Enhance Economic Development

 Middletown Honored for Water and Sewer Improvements

This article was published by Pennsylvania Municipal Authorities Association in the August 2017 issue of their magazine, The Authority.

Construction equipment has become a familiar sight to the residents of Middletown Borough in recent years. New businesses are popping up alongside historic buildings in the borough’s downtown business district – thanks, in large part, to a major revitalization effort spearheaded by local government officials.

And it all began by replacing the area’s water and sewer facilities.

The success of Middletown’s revitalization effort illustrates the key role infrastructure plays in building and sustaining great communities. Borough officials and local business leaders wanted to enhance economic development by attracting new businesses to downtown Middletown, but water and sewer problems threatened to kill the success of their efforts before they’d begun. Many communities could’ve seen their dreams derailed by an obstacle like this, but the borough persevered because of strategic planning and the collective effort of a community united behind a common goal. The borough’s story illustrates how communities can overcome barriers and successfully address aging infrastructure in order to enhance economic development.

 

Aging Infrastructure Presents a Barrier to Development

The Borough of Middletown has the distinction of being the oldest community in Dauphin County. The town was first laid out along the Susquehanna River and Swatara Creek before the Revolutionary War, and brick sewers in the historic downtown area were first installed not long after the Civil War.

Middletown Pre-1900 Sanitary Sewer

Some of Middletown’s water and sewer lines dated back before 1900. 

Unfortunately, the sanitary sewer and water facilities located in the downtown business district were not supporting current demand (and they certainly weren’t adequate to meet the demands of new development). The condition of the assets were a risk to the downtown revitalization efforts. In addition, cross-connections between the sanitary sewer system and the storm sewer system led to surcharging and sanitary sewer back-ups.

These challenges made it hard to keep existing businesses downtown and attract new ones. In addition, the borough was planning a streetscape project that would place numerous aesthetic improvements directly above the aging water and sewer facilities. The community did not want to see their investment in these improvements threatened by excavation to repair the sewer and water facilities soon after construction was complete.

 

Water and Sewer Improvements Lay the Foundation for Future Development

Borough officials asked Herbert, Rowland & Grubic, Inc. to design upgrades to the water and sewer facilities in the heart of its downtown business district (along South Union Street from Spring Street to Ann Street). This project was to be the first phase of its downtown revitalization plan. It included:

  • Replacing deteriorated brick sanitary sewer mains with 1,467 feet of new PVC sanitary sewer main
  • Eliminating hydraulic “bottle-necking” that restricted sewer flows to the Mill Street Interceptor
  • Replacing 7 deteriorated manholes with new precast concrete manholes
  • Replacing 44 sewer laterals
  • Designing and replacing 2,042 feet of water main
  • Replacing 4 hydrants
  • Installing 14 valves to isolate future maintenance work as the community continues to upgrade its water infrastructure and to allow for future fire system services to new businesses

HRG began design work in 2013, and construction was complete in 2014. They accelerated the project schedule to reduce stress to the existing local businesses.   With the risk of failing water and sewer facilities mitigated, Middletown could begin Phase II of its revitalization effort: improving the streetscape (with new decorative paving, curbing, sidewalks, and street trees) and providing traffic calming devices to promote pedestrian access to the businesses.

The Community Comes Together to Make This Project a Success

Efforts to revitalize the downtown business district had generated excitement in the community. Local leaders, business owners, and residents understood that these infrastructure upgrades were vital to attracting new business to the area, and they embraced the investment this project would require.

The former Middletown Borough Authority, the borough, and the Middletown Borough Industrial and Commercial Development Authority led the revitalization effort and engaged the public throughout the process. They held numerous meetings with the public and with local stakeholders to communicate the vision and direction of the project. The project team worked extensively with the owners of local businesses along South Union Street, soliciting their ideas and accommodating special events to minimize disruption to business activity.

Thanks, in part, to these open lines of communication, the project team was able to maintain water and sewer service to the existing businesses in the area throughout the project (despite having a confined working area due to the presence of numerous other utilities).

The engineers also coordinated extensively with other project partners to ensure a smooth transition from Phase I (water and sewer improvements) to Phase II (streetscape enhancements). For example, they coordinated extensively with the streetscape design team to ensure that the water and sewer improvements would not conflict with proposed streetscape facilities, and they worked closely with the landscape architect to ensure that above-ground features like hydrants and manhole covers were installed at locations that would not impact the streetscape visual design concepts.  This saved the borough money and ensured that above-ground features would not have to be relocated during Phase II to achieve the aesthetic goals of the streetscape enhancements.

Detailed records about the location and depth of sewer laterals by HRG’s resident project representatives during construction of Phase I provided further cost savings. This information was used for deciding the depth of stormwater facilities in Phase II, reducing design fees in that phase.  It also prevented costly change orders that often come from unknown utility locations.

 

Middletown Streetscape

The Improvements Begin to Generate New Development Interest

It didn’t take long for all of this activity to generate interest from developers and business owners in opening new ventures in the area. While the project was in its construction phase, a developer proposed a 100-room hotel with retail space on the first floor just a block away from downtown. The developer also expressed an interest in working with the team behind the streetscape design to develop other projects in the area.  He specifically mentioned the downtown revitalization efforts as one of the factors in his decision to invest in the area.

Patrick Devlin of the Tattered Flag Brewery and Still Works also mentioned the flurry of activity downtown as a factor in choosing to locate his business in the old Elks Building. The brewery opened in December 2016 and was recently named the New Business of the Year by the Harrisburg Regional Visitors Bureau.

Business investment like this is expected to continue in Middletown and the surrounding communities. The new sewer infrastructure mitigated a known risk, increased efficiency, and gave the borough additional capacity for the anticipated development.

The water and sewer improvements were completed two weeks ahead of schedule and almost $400,000 under budget. This new infrastructure proved to have a much lower maintenance and operations cost than the aging infrastructure it replaced, and it has drastically reduced infiltration and inflow into the system. During an early phase of design, engineers found and eliminated a cross-connection between the aging sanitary sewer and the borough’s storm sewer system.  By eliminating this cross-connection, they were able to prevent approximately 500,000 gallons of stormwater from entering the sewer system during a typical rain event.  In fact, since the project was completed, the system has not experienced a single sanitary sewer overflow, and no sewer back-ups have been reported along North Union Street. (You can read more about the correction of this cross-connection here.)

Investing in a project of this magnitude is hard for many communities, but Middletown’s story shows it is possible and the benefits are wide-ranging. When well planned and executed, updated infrastructure lowers maintenance and operations costs, enhances the quality of service to a system’s customers, and helps to attract growth and investment in the community.   When citizens and business owners join forces with the local government and think creatively, the seemingly impossible task of upgrading our aging infrastructure while promoting economic development becomes possible!

How to Choose the Best Method of GIS Data Collection for Water and Sewer Systems

Carlisle Borough Uses Infiltration/Inflow Data to Devise Long-Term Plan for Infrastructure Repair and Replacement

Like many municipalities, Carlisle Borough is grappling with the challenge of aging infrastructure. Its sewer system features infrastructure that is more than 100 years old.  Since replacing it all at once is not possible from a financial perspective, borough officials needed to a way to narrow down exactly where investment should occur.  Which projects would provide the most value to Carlisle residents and business owners?  Infiltration and inflow data provided the answer.

Why infiltration and inflow data?

In the words of Carlisle Borough staff, “Inflow and infiltration is really just a symptom of failing infrastructure.” By figuring out where extraneous flow is entering the system, we get a hint as to where cracks or defects in the infrastructure may be located.

Josh Fox recently authored an article in the April/May/June issue of Keystone Water Quality Manager magazine on this project with the borough’s director of public works Mark Malarich, P.E.

The article discusses how HRG’s engineers evaluated infiltration and inflow data to determine what infrastructure needed repairs or replacement the most. First, the borough implemented a 16-week metering program to identify dry weather flow for comparison to wet weather data for the borough’s 21 sewer basins.

We then used the data to calculate peaking factor and total infiltration volume for each of the basins and ranked the basins accordingly. After analyzing the data, we determined that some basins had high peaking factors but infiltration dropped off quickly once the wet weather dissipated (like Area 1C in the figure below).  Other basins saw high infiltration volumes for several days after a wet weather event (like area 4 in the figure below).  This suggested that a high groundwater table was contributing a sustained flow via defects in the manholes, sewer mains and sewer laterals.  Therefore, total infiltration volume provided the best data for assessing the overall condition of the infrastructure.

 

Infiltration-Inflow-Data-from-Two-Basins

Taking our analysis one step further, we prioritized the basins with the highest total infiltration volume for further investigation and compared the total volume of infiltration/inflow in a basin to its size. By calculating the total infiltration per foot of pipe, we were able to more accurately estimate the severity of damage in each basin.  (For instance, two basins may have had similarly high total infiltration volumes, but one was significantly smaller than the other.  This suggests a higher severity of defects in the smaller basin for that much water to infiltrate in a smaller space, during the same time period, after the same wet weather event.)

Prioritized Basins by each factor

Using this data as a guide, HRG worked with the borough to devise a 20-year capital improvement plan for addressing the highest priority needs in the system.  HRG also helped the borough create a financial strategy for addressing these needs.

Rehabilitation of the highest priority basin is being completed in the spring of 2017 and is expected to come in almost $1 million under budget.

Benefits of Utility Asset Management

As our water systems continue to age past their useful life and utilities face increasing budget pressures, the terms asset management and capital improvement planning have become buzzwords in the industry. However, as utility managers struggle to squeeze as much out of their budgets as possible, it is hard for many of them to justify the additional expense associated with developing and implementing an asset management program. Just like with any other purchase, they want to be sure the benefits outweigh the cost.  So what are the benefits of asset management and capital improvement planning?

Target your money with asset management

Target budget dollars where they’re needed most and eliminate wasteful spending.

An asset management and capital improvement program helps you identify exactly what maintenance and repair work is necessary without guesswork. Why allocate money toward cleaning out pipes selected at random, when you could target that money to the pipes that need it most (and use the savings to accomplish other system goals)?  Why replace pipes simply because of age when they may be in perfectly good condition?  Many factors besides age can cause the deterioration of infrastructure.

Minimize Risk

Knowing which infrastructure is most likely to fail (and correcting deficiencies before it does) can save you major expenses later in the form of property claims, water loss, etc. Knowing which failures would be the most catastrophic helps you target money toward their prevention as a first priority. With the budget limitations of municipal utility management, you might not be able to prevent every system failure, so it’s important to know which ones have the potential to cause the most financial damage and impact the most customers.  This way, you can focus your efforts on preventing those first.  If a failure does occur, a good asset management plan will include a proactive response plan, allowing you to respond quicker and more efficiently (thereby reducing damage and disruption).

Increase ROI with asset management

Maximize Returns

Asset management and capital improvement planning is all about proactively investing in measures to extend the life of your infrastructure.  These small investments can extend the life of an asset by several years.  Over time, the money you save delaying replacement will far surpass the money you spent to maintain the asset, and your customers will have enjoyed better, more consistent service for this lower cost.

Water sustainability

Promote Sustainability

Finding and detecting failures in the system like leaks can prevent water loss and the wasted energy consumed to treat water that never makes it to a customer.

Optimize Customer Service and Satisfaction

Proactively maintaining your assets ensures they function at peak performance for a longer period of time and are replaced before they fail. This means your customers receive top quality service without disruption and are happier for it. In addition, many asset management solutions include optional customer service applications that make it easier for customers to submit service requests and track them to completion.

 

Justify your rates with asset management

Justify Your Rates

Rate increases are never popular with customers, but they are easier for them to accept when they are backed up with clear data showing exactly what improvements are needed and why.

Attract funding with asset management

Access grants and loans

Competition for funding is fierce, and government agencies are under pressure to make sure the money they invest is used wisely. As a result, they’re more likely to award funds to utilities who have clear documentation of the project need, its benefits, and a plan for getting it built, operating it, and maintaining it at optimum levels over time.

Know your worth with asset management

Know your worth

Many utilities have been considering the option of leasing or selling their assets as a response to growing financial obligations in the public sector. A comprehensive asset management system provides documentation of the value of your assets, so you can ensure you are in a position to negotiate the best possible deal for you and your customers.  Potential investors will be more comfortable making a significant investment if they fully understand the value and the risks they’re assuming. (For more Insight into the utility leasing trend, see our article on calculating fair annual rental value.)

Every manager must take careful stock of his revenue and his expenses, but not all expenses are created alike. There is a difference between a cost and an investment, and asset management is clearly an investment in your utility’s future.  In essence, it helps you provide better service at a lower cost with reduced risk and improved financing options. How many investments can you make that provide that kind of return?

Asset management can also be a valuable tool for municipalities managing a stormwater system. As MS4 permit requirements continue to grow, municipalities need to know more and more about the location and condition of their stormwater infrastructure. HRG has extensive experience creating asset management systems for stormwater systems, and we offer a wealth of advice about meeting MS4 permit requirements and funding stormwater program needs through user fees.

Effective Utility Management Starts With These Strategic Planning Tips

Strategic Planning Whiteboard

This article was originally published in the June 2016 issue of  Keystone Water Quality Manager. It is reprinted here with their permission.

We’re all familiar with the phrase “If you don’t know where you’re going, any road will get you there.” This is paraphrased from an exchange between Alice and Cheshire Cat in Lewis Carroll’s Alice in Wonderland. Like Alice, you know you need to get “somewhere” because changing regulations, increasing costs, aging infrastructure and customer growth affect the way you provide your service. Each year as operators, managers, and board members, you’re forced to establish budgets, adopt rates and policies, and make recommendations that have long-lasting effects. You may use the best information available at the time but can’t be sure that you’re adequately prepared for what’s just around the corner.

Strategic planning is a tool that helps to identify where you need to go and the best road to get there by exploring the fundamental values and principles that support your utility’s policy and operating decisions. Properly done, it looks at all aspects of the utility’s operations in order to see if they reflect the needs of your customers, ensure regulatory compliance, and generate sufficient financial resources to be sustainable. This is not just a financial plan focused on replacing existing facilities or acquiring new ones, but a comprehensive look at the factors that will drive both short and long-term events and an identification of strategies to address them.

There are five basic elements in a strategic plan:

  1.  Vision
  2. Mission Statement
  3. Critical Success Factors
  4. Strategies and Actions to Meet Objectives
  5. Prioritization and Implementation Schedule

However, there can be as many additional elements as the utility feels is necessary to properly address the needs of all its stakeholders: its users, employees, and the community at large. Some of these elements may take a long time to complete, while others can be accomplished relatively quickly. For some, a good deal of data will be needed, while others will simply reflect widely accepted industry practices and preferences. The plan could take a month or a year to complete, depending on the level of detail believed to be required. However, one of the benefits of the planning process will be simply identifying the stakeholders and discussing the elements of the plan with them. The ability to identify areas of consensus and concern is a hugely important and valuable outcome of the plan.

Getting Ready for Strategic Planning

Before you can begin the process, there are some preparatory activities that should be completed:

Authorization
The first task in strategic planning is obtaining the authorization to move forward with the process at all. It is important to involve all of the decision-makers in the strategic planning process, and discussing the scope of the plan and its benefits is one of the best ways to achieve “buy-in” for the entire process. Without buy-in, it will be difficult to fully implement the resulting plan.

Identification of Stakeholders
Another important step is to make sure the process considers all relevant points of view. This may seem easy, but, when you actually begin to list them, the number of people and organizations relying on your utility to be well-managed and provide affordable, high quality service is probably greater than you think. While some seem obvious, consider the following examples:
• Current users
• Employees
• Regulatory agencies, including PA DEP and US EPA
• Municipal government, conservation districts and planning agencies
• The Chamber of Commerce or local economic development agency
• Future users, including land owners and developers

This is not intended to be a complete list, only a guide, and not every group will require the same level of involvement in the strategic planning process, but understanding how each group might be impacted is important.

Planning Your TimetableDetermination of the Plan’s Time Frame
Strategic plans are generally long-term, usually five years, but a different time horizon may be more useful if you are aware of some specific event likely to occur just beyond the five-year planning period. If a significant expansion of the utility appears likely, five years may not be long enough.

Organization
How will the strategic plan be organized? Who will guide the process? Is it to be done by an outside professional or internal staff? What is the schedule? What will the final plan look like, and how will it be disseminated? Does it need some type of formal adoption or approval? If so, by whom?

Determining the “Vision”

In essence, visioning asks the question: What will the organization look like in the future? Visioning will supply the context for the other elements of the strategic plan. For a wastewater utility, the visioning process may actually be one of the most involved elements of the plan since this is where you try to get a peek at what’s around the corner. Unlike some businesses where visioning is a projection of some blend of marketing prowess, economic predictions and industry trends, each utility is unique because the factors that drive future events will impact it differently.

The task is made a bit easier if you divide visioning into an external scan and an internal scan. Although they may be related in many ways, the external scan looks at:Financial Reports

  • potential changes in the regulatory environment,
  • community growth and development,
  • changes in demographics,
  • future interest rates,
  • future construction costs,
  • the overall level of economic activity.

(Increased economic activity in nearby communities should also be considered since it may impact your service area.)

The internal scan will focus more on:

  • the needs of existing users and employees,
  • service improvements,
  • transparency,
  • facilities,
  • finances,
  • rates,
  • operating policies,
  • organizational structure.

These are but a few of the areas that need to be considered in some detail.

The visioning process is almost as diverse as the elements themselves. Clearly, information from outside the utility is necessary. This may include individual interviews with consultants, suppliers and community leaders. Telephone calls, questionnaires, online surveys, and specific messages printed on bill inserts can also solicit feedback from targeted stakeholders. Regardless of how it’s done, the result should be a clear and concise statement that reflects the major trends that are likely to drive the future direction of your utility. But, before you can get too specific, you should develop the broad organizational goals. This is best done with a mission statement.

Drafting a Mission StatementDrafting Your “Mission Statement”

I know the idea that you can somehow cram the entire essence of an organization into a couple of tightly worded sentences seems impossible. Some mission statements will run on for several paragraphs, but do they really provide more information about the philosophy or principles that govern the utility’s operations? Usually not. Instead, the discipline of packing an organization’s values into a few words may actually provide a better understanding of its goals. Here is an illustration of a short but insightful mission statement for a wastewater utility, courtesy of the Lancaster Area Sewer Authority:

“To provide quality service and apply technology to process wastewater so as to protect and enhance the environment and health and well-being of the community at a reasonable cost.”

The mission statement should not simply be a collection of carefully chosen words that project an image that isn’t consistent with the utility’s values; rather, creating the mission statement should foster a deeper understanding and commitment to those values. This, in turn, provides the benchmarks that measure success.

business-servicesIdentifying “Critical Success Factors”

The visioning process should identify the broad goals and major initiatives that need to be incorporated into the strategic plan. It is not important to determine their feasibility at this point; detailed examination of alternatives will be done later. Simply decide if they are consistent with the mission statement and are not mutually exclusive. Some likely success factors might include:

  • Achieving greater transparency.
  • Building up operating and capital reserve accounts.
  • Having all professional employees become certified in their specialty.
  • Exploring alternative billing and payment procedures.
  • Creating or reviewing emergency response procedures.
  • Reviewing or increasing use of technology to achieve greater efficiency.
  • Expanding facilities to accommodate expected population increases.
  • Developing an action plan should demographic changes result in reduced flows.

These are only illustrations; the vision and mission statements will help dictate the critical success factors that should be included in your plan. The key here is to keep the success factors general in nature but focused on specific identifiable outcomes. Another important consideration is quantifying what it means to be successful and the metrics for measurement.

From the above illustration, achieving greater transparency is a success factor, but what exactly does that mean? What is it that should be more transparent, and what are the limits of what is made publically available? Can it measured by the number of visits to your website, or does it mean the creation of a website? Is it measured by a fewer number of requests for specific information or telephone inquiries? How about the development of a newsletter? Is that something that most customers believe would be useful based on data collected during the visioning process?

Some critical success factors may not be determined directly. In the example above, data may not have been collected on customer’s preferences during the visioning process. In that case, the success factor of achieving greater transparency will need to be defined by some other precedent activity to measure the benefits of transparency, or it may be determined that transparency is simply a virtue for its own sake whose benefits may not be immediately measurable. In that instance, the precedent activity may be to look at industry practice and see how your current practices can be improved.

If you are getting the idea that developing the critical success factors is a time-consuming process that requires a lot of effort in order to be done correctly, you’re right. This is often the work of several individuals and should involve a team approach at least to direct the work. Care should be taken to assign responsibility for completing an assignment to someone who is involved in the overall planning effort. If not, they may not understand the actual goal and may simply complete a task.

Developing critical success factors, defining them, and providing metrics for measurement is at the very heart of the strategic planning effort. While strategies and actions will provide the “to-do list” and ultimately become the basis for the final report, they will be driven first by the critical success factors you’ve defined.

Developing “Strategies and Actions”

This step is where the plan is actually created. Critical success factors identify the areas where some action seems warranted; they take our broad goals and further define the “somewhere” we want to go. The next step is determining how to get there.

negotiating_at_the_deskAgain, using the transparency example, probably everyone will agree that organizational transparency is desirable, but someone might disagree with the type of information that is made available or with the level of training that may be necessary to organize and screen information. Cost is always a consideration when implementing changes.

Because there are generally many facets to each critical success factor, it is important to have several individuals involved in formulating the strategy for evaluation and implementation. This is often accomplished by group meetings, where each critical success factor is discussed. Questions will likely arise that cannot be answered without some further investigation, so tasks must be delegated to a smaller group or an individual for follow-up. In fact, most of the early efforts will be directed to developing the process to obtain the necessary information and assigning someone to gather and analyze it. The analysis is essential so that the success factor can be implemented in a way that achieves its intended purpose. It also provides documentation for any critical success factors that cannot be implemented.

Once the strategy for implementation is determined, specific detailed actions for implementation should be prepared. One of the most important decisions in this stage of the process is timing. You want to think about the best time to launch a new initiative or modify or eliminate an existing one.

Another important task is to identify someone to champion the implementation. Maybe there is one lead person or several depending on the type and number of tasks. If achieving the critical success factor requires technology changes, someone involved with maintaining that technology should be involved in the implementation. This may seem obvious, but sometimes third parties are retained for implementation, resulting in a loss of buy-in from those who will be responsible for making it all work.

Prioritizing Tasks and Designing an Implementation Schedule

Even though this article opened with a reference to a fairy tale, there should be no fantasy about implementation. It’s just as much work as each of the other elements — maybe more, since there are now clear ideas on how each goal is to be achieved and, of course, the devil is always in the details. Regardless of how thorough the analysis was, complications can be expected. Another frustration usually is that it takes longer to accomplish than originally believed.

In order to avoid this, one of the first steps to implementation is to determine the schedule. Unless there are very few and straightforward critical success factors, some effort needs to be expended in prioritizing each success factor for each of the broad goals identified in the vision. Often, once the strategic plan is formalized, a sense of urgency to implement its objectives is inevitable. This is understandable since the reason for the plan is generally to improve the utility’s operations, so why would you want to delay?

For one thing, it’s important to remember that the plan itself looks at a five-year time period, so that not all benefits will be immediately available. Also, events are constantly changing, so some of the fundamental assumptions that went into the plan may change. This may not affect the plan, but the implementation schedule should allow time for monitoring external changes nonetheless.

Another important consideration is the time staff has available to implement the plan. While the plan is being implemented, all other work must continue. Even if some of the heavy lifting is assigned to others, the utility’s staff needs to be involved at each step if they are expected to achieve the plan’s goals and provide necessary feedback.

microphoneCommunicating the Plan with Your Stakeholders

Okay: you have the vision, you’ve determined the critical success factors, you’ve developed strategies for implementation, and you’ve created the implementation schedule. You have assigned staff to implement the various strategies in order to monitor progress and make sure that each strategy achieves its desired goal. One question remains: What does the final plan look like? Is it a printed document, a slide presentation published on your website, or an internal spreadsheet that serves as a checklist for monitoring implementation?

Like all the other aspects of the plan, the process that rolls out the plan is determined by the goals of the strategic plan itself. If the plan is centered on internal improvements, then employee meetings with handouts may be the most effective means of communicating the plan’s objectives and the strategies designed to implement them. If there are elements of the plan that are service-related – that impact your customers or the community at large – more formal printed materials may need to be prepared. Meetings with important relevant stakeholders may also be useful, especially if there are some financial impacts associated with the plan that they are expected to share.

The only thing that’s constant is change. Absent a crystal ball, tarot cards, or an Ouija board, a well-thought-out strategic plan is the best means of seeing the future. Even if it misses the mark, knowing why it missed and what parts of the utility may be affected is an important benefit that makes the exercise worthwhile. At the very least, developing the plan will require policy-makers, managers and staff to consider each other’s points of view and understand how the customers and community view your utility.

Sanitary Sewer Overflow Solution Comes from An Unlikely Source: A Fish

Sanitary Sewer Overflow

This article on how Middletown Wastewater Treatment Plant solved its Sanitary Sewer Overflow problem was originally published in the June 2016 issue of Keystone Water Quality Manager. It is reprinted here with their permission.

No doubt a fisherman would be intrigued seeing a rock bass on the fine screen at the Middletown WWTP, but the ear tuned to hear “inflow” was even more intrigued.

The visit from the rock bass had been preceded by two decades of inflow reduction efforts due to Sanitary Sewer Overflow issue (SSOs). Yet despite increased interceptor sizes and redirected flows, the SSOs continued. A sewer system dating back to the 19th century can indeed be challenging, but sometimes solutions are inspired in the unlikeliest of ways.

Discovery of the rock bass was mentioned casually at an authority meeting, and immediately the authority’s engineer began to wonder if there was an unknown connection between the borough’s sanitary sewers and storm sewers. Rock bass are not kept as pets, of course, so the fish would not have entered the system from a toilet or home drain. It must’ve come from Swatara Creek.  There is no way the fish came through the WWTP effluent pipe, and only the local storm sewers discharge to Swatara Creek, not the sanitary sewers.  Therefore, the fish must’ve entered the sanitary system directly from a connection with the storm sewers.  But where?

After several discussions with treatment plant operators and other staff at the borough and authority, the engineer was able to narrow the search down to three possible locations, one of which was located at the site of a streetscape project under construction at the time. Searching this area for a sanitary and storm sewer connection would be very difficult because it was the heart of the borough’s downtown business district and was surrounded by a nest of other utilities and old Brownstone businesses.  Yet the effort was worth it: By carefully coordinating with the contractor, the borough was able to discover the unknown connection between the local sanitary and storm systems, and, once it was corrected, sanitary sewer overflows (and basement back-ups at local businesses) were finally eliminated!

Middletown sewer connection

This story illustrates the importance of harnessing the feedback and input of your operators and staff at all levels of an authority’s organization. Had the operators’ odd discovery of the rock bass (later nicknamed Leaky) never made it to the authority and their engineer, SSOs could’ve potentially continued in the borough for many years.  Operators possess unique knowledge of a system’s materials, construction and history.  This knowledge has real value that can lead to major cost savings like those realized by this solution to the borough’s inflow problems.

As this story shows, incorporating the input of operators and staff at all levels of an organization can make finding solutions to your most puzzling challenges as easy as shooting fish in a barrel (or fine screen).

Lead: Water Systems Face More Stringent Enforcement, Revisions After Flint

by Edward Ellinger, P.E.

The water crisis in Flint, Michigan, has brought renewed focus to the impact of lead in our drinking water, and water systems are likely to see increased enforcement and oversight in the near future as a result.

EPA to Meet With State Officials, Water Systems to Ensure Compliance with Current Rule
On February 29, EPA administrator Gina McCarthy issued a letter to governors informing them that EPA representatives will be meeting with state drinking water program officials to assure that they fully understand the requirements of the Lead and Copper Rule and are enforcing the program properly. She asked governors to communicate the importance of this effort to their agency officials and to increase education and outreach aimed at informing the public about lead risks. The goal is to provide better information in a more timely fashion.

Education should include notifying water customers if there are elevated lead levels in their water system as quickly as possible and providing guidance on how they can reduce lead-related health risks. It should also leverage available technology to share sampling protocols and results publicly in order to provide transparency and promote renewed public trust.

Deputy Assistant Administrator Joel Beauvais issued more detailed guidance to state regulators, urging them to verify state standards for enforcing the Lead and Copper Rule are in accordance with federal guidelines. This guidance included a technical memorandum clarifying the Lead and Copper Rule sampling protocols.

Beauvais echoed McCarthy’s call for transparency by asking regulators to work with local water systems to post their compliance activities and lead monitoring results on the water system’s website or the state’s website. He also stressed the need to ensure affected customers are informed of elevated lead levels promptly and given guidance on how to minimize their health risks.

Beauvais said EPA will be providing Lead and Copper Rule training to state and public water system officials in the coming months and is in the process of strengthening the Lead and Copper Rule to further minimize health risks due to lead exposure.

EPA has, in fact, been working with stakeholders to revise the Lead and Copper Rule for several years now. The updated rule was initially expected to be released this year, but is now expected in 2017 instead.

The main group advising EPA on these revisions is the National Drinking Water Advisory Council’s Lead and Copper Rule Working Group. Members of the group include leaders of public water systems, public health departments, environmental groups, and children’s advocacy groups.

Lead Service Line Replacement
The group recently released a report of its recommendations for the Lead and Copper Rule revisions. The most notable of these recommendations is a push for water systems to implement a lead service line replacement program. This program would be designed to completely replace all lead service lines in the distribution systems by 2050. All water systems would be required to inventory their lead service lines and work with customers to participate in the program with regard to the portion of the line owned by the homeowner. This inventory would include notifying homeowners that their service line contains lead, the health risks posed, and the steps they can take to replace the line. It would also include strict record-keeping to track how often the homeowner was contacted and the response provided by the homeowner.

While the water systems would be given credit for service lines if the homeowner outright refused to replace their portion of the line, this credit would only be given after the system had exhausted all efforts to engage that homeowner. In addition, the system would have to continue to reach out to the consumer every three years or every time a home changed ownership.

The current regulations only require replacement if corrosion control chemicals do not bring lead concentrations below the regulatory threshold, and only a few systems in the U.S. have successfully implemented programs to completely replace all lead lines. Madison, Wisconsin, was the first to succeed in this effort in 2012, and Lansing, Michigan, is expected to complete replacement of its lines in the summer of 2017.

Aside from the fact that most public water systems don’t have sufficient budget for such a major capital investment without the benefit of grant funding or increased user rates, the complete replacement of lead service lines is complicated by ownership and cost responsibilities between the homeowner and the water system. The members of the Lead and Copper Rule Working Group recognize these challenges and have stated that successful replacement of lead service lines will require creative financing and a commitment by federal and state agencies, consumers, and private industry alongside the water system.

Increased Public Education and Outreach Responsibilities
Another major focus of the Working Group’s recommendations is public outreach and education. Because homeowners have shared responsibility for the replacement of lead service lines, it is imperative that they be educated about the location of these lines and the health risks presented. The current Lead and Copper Rule merely requires public education and outreach if the lead action level is exceeded.

Water systems are limited in their ability to completely eliminate lead in tap water. Most consumers don’t realize that lead exposure is typically a result of corrosion in the service lines leading to their home and that testing at the water treatment facility cannot rule out high lead concentration.

Therefore, the Working Group recommends that all consumers be proactively informed of the health risks caused by lead in drinking water, the likelihood that their water may contain lead, the responsibility they bear in eliminating lead in their drinking water (including the replacement of private service lines), and the resources available to help minimize their risk from lead exposure.

This effort includes the creation of a national clearinghouse of information concerning lead in drinking water. This clearinghouse would discuss lead-related health risks and provide consumers with information on how to get their water or their blood level tested. It would also inform the public about the sources of lead in drinking water and how to determine if they have lead service lines. For homeowners that are served by lead service lines, there would be a comparison of partial service line replacement versus full service line replacement as well as information about the costs of replacing their service line and the financing available. The site would also discuss home devices such as filters.

The Working Group recommends requiring water systems to send new customers information about “the potential for lead from plumbing materials to contaminate drinking water even when the water system meets federal requirements, to contaminate drinking water in homes with and without lead service lines, and to pose chronic and acute health risks to vulnerable populations.”

The group likewise recommends clearer language about lead in the water system’s annual Consumer Confidence Report that would emphasize the need for homeowners to take an active role in reducing lead in their tap water. It would clearly explain the role lead service lines play in the presence of lead in drinking water and the shared responsibility homeowners have with the water system to eliminate these lines. The new language would also encourage customers to have their own water tested rather than rely on the relatively small sample size being taken by the water system.

While encouraging homeowners to take an active role in lead exposure prevention, the Working Group wants to empower them in this role by increasing public access to information about lead in their local water system. The current Lead and Copper Rule only requires water systems to provide a general statement in their annual Consumer Confidence Report about the 90th percentile value of the most recent round of sampling and the number of sampling sites that exceeded the action level. More detailed information on the sampling data may not be available or may be prohibitively difficult to obtain. The Working Group recommends that the water system augment the currently required statement with more detailed sampling results (including the median levels reported), information on the sampling protocols, and an inventory of confirmed and presumed lead service lines.

Regular Re-Assessment of Corrosion Control Methods
While the current rule requires water systems to reassess corrosion control techniques whenever a change in source water or treatment technique is planned, the Working Group is recommending that water systems also be required to monitor EPA guidance on an ongoing basis to see if new scientific evidence warrants evaluating a new approach to corrosion control.

The Working Group recommends that EPA publish new guidance on corrosion control techniques every six years. Water systems would then be required to confirm that they reviewed this guidance and evaluated whether it warranted updates to their approach. Not doing so would be a violation of the rule.

Other recommendations for the 2017 Lead and Copper Rule revision include:

  • Increasing the frequency of water quality parameter (WQP) monitoring for process control and tailoring the WQP to the specific corrosion control plan for each system.
  • Separating copper into its own rule and creating new requirements specifically geared to eliminating copper corrosion: “The issues associated with lead and copper are very different and warrant more separate attention than has been the case in the past.”
  • Modifying the monitoring requirements to provide for consumer-requested tap samples and using those sample results to assess the success of corrosion control methods. This effort would provide a more complete picture of lead in the water system by increasing the pool of samples and sampling dwellings that the current rule does not prioritize. With more frequent and thorough data, the water system could better evaluate the effectiveness of its corrosion control program and make adjustments as needed.

The Working Group’s recommendations are currently under review, and the official rule is anticipated to be released by the EPA in 2017. In the meantime, water systems should make sure that they are intimately familiar with the current Lead and Copper Rule requirements and continually work with their operators and engineer to go above and beyond from a compliance and public outreach standpoint.

As the EPA begins to meet with state regulators and water system officials, water system managers and operators will need to be fully informed of the current rule and the water system’s approach to managing lead. In addition, water system managers will need to consider the anticipated changes coming next year and plan for compliance.

Assessing the Condition of Large Sewers

Figure1Determining the condition of large sewers can be challenging, but multiple tools are available to help. This article, which was published in the October 2015 issue of Keystone Water Quality Manager magazine, provides a brief review of large sewer condition assessment tools and gives some guidance in deciding which to use.

Knowing the condition of your sewer system now can save you major headaches (and money) down the line. The investment you make today in conducting regular inspections of your pipes and pump stations will help you avoid emergencies like burst pipes and sewer overflows tomorrow, but it will also help you make better decisions about where to allocate limited revenues in terms of maintenance, repairs, and replacements.

Even though the investment in a condition assessment is worthwhile, you want to make sure you spend those assessment dollars wisely and get the data you need in the best possible quality for the lowest possible cost. Many tools are available, and each one is suited to particular needs. Which tool is right for your system? Let’s take a look at the strengths and limitations of some of the most popular methods of sewer inspection available today.

 Knowing What Each Tool Can Do

1. Zoom Camera
A handheld or truck-mounted zoom camera is a great tool for quickly assessing the condition of large sewers. A zoom camera enables you to see for several hundred feet down the sewer line, but the view is limited by any obstruction to line of sight (such as grease, cobwebs, debris or a deflection in the sewer). In addition, the camera will only allow you to see above the water level.

2. Acoustic Assessment
Another quick assessment method is the use of acoustics. The ability for sound to pass through the sewer provides an indication of whether a blockage exists or not. However, it is not a complete assessment and will require some additional inspection work. Still, an acoustic assessment can cost about a quarter of the price of basic closed circuit television, so it can be used to save money by focusing more expensive data collection methods only on areas the acoustic assessment has identified to have potential blockages (as opposed to using a more expensive, but more thorough tool throughout the entire system).

CCTV

3. Closed Circuit Television (CCTV)
CCTV has been used for many years to evaluate sewers, and it can be customized to the needs of your unique system because of the different types of cameras and vehicles that are available. A conventional pan and tilt camera may be sufficient for some pipes, but a fish-eye type camera lens can be used for a virtual pan and tilt that is somewhat more comprehensive.

CCTV provides a visual assessment of the sewer, but it can also be helpful in identifying buried manholes or revealing other unknowns in the connectivity of the sewer system.

In the past, it was a challenge to obtain sufficient lighting to get a clear picture of large sewers (see figure on the right), but new technology solves this problem by using a strobe light and stitching a series of images together, rather than recording continuous video.

4. Sonar
While some tools like the zoom camera cannot provide data on the condition of pipes below the water surface, sonar can. Therefore, it is useful for identifying debris and sensing connections below water level. However, some water must be in the sewer for the use of sonar to be possible.

Laser Profiling

5. Laser Profiling
Laser profiling can reveal buried manholes or other connections to the sewer that may not have been realized and can also be used to assess pipe wall loss (as long as the original sewer size information is available and can be entered into the software). However, like the zoom camera, laser profiling can only be used to see above the water level. Therefore, it’s wise to combine it with sonar and CCTV in order to get a complete assessment of the sewer condition, as seen in the figure on the right. (The red shows results from the laser, while the blue shows results from sonar.) For a recent project involving 70,000 feet of sewer, the cost to use these three tools together was approximately $5-6 per foot.

6. LIDAR (3D Laser)
LIDAR is an advanced technology alternative to standard visual and photographic inspection methods. It uses 3D optical scanners to collect simultaneous data and images, which can be used to produce a 3D model of the sewer. This model can then be used to measure, identify deficiencies, and make recommendations for rehabilitation or replacement. It can also be used in 3D infrastructure system modeling and management applications when combined with equally accurate pipe and structure positional data. One instance 3D data is especially useful is in manufacturing the lining for a bend in a sewer.

As an advanced technology, LIDAR provides more comprehensive data than a zoom camera or CCTV inspection could. As an added bonus, the optical scanners are typically inserted into the sewer from the surface, eliminating the need for a person to enter the confined space of the sewer and the associated dangers they could encounter.

7. H2S Gas Sensor
An H2S Gas Sensor is helpful in cases where there is concern about corrosion. The sensor can be mounted on a multi-sensor platform to provide additional insight into the state of the sewer.

8. Gyroscopic mapping
Gyroscopic mapping is used to obtain X-Y-Z coordinates of the sewer along its length, so it’s helpful for identifying the location of bends or changes in elevation. However, this tool requires known X-Y-Z coordinates at the starting and ending points of a sewer.

For large sewers, a small pipe needs to be pulled through the large pipe as a host for the probe, leading to some limitations in the information gained. However, this tool can be useful for facilities such as force mains where changes in direction are often not seen from the surface.

9. In-pipe Ground Penetrating Radar (GPR)
GPR inside the pipe gives insight beyond the sewer itself. It can reveal void spaces outside the sewer line, such as may be caused by infiltration. It can also shed light on the thickness of concrete covering rebar in the sewer.

Deciding Which Tool is Right for You

With a clearer picture of what each tool can and cannot do, you’re better prepared to decide which one will produce the best results for your system. In doing so, here are some things you should consider:

1. Understand your goals.
Consider what you want to gain from the assessment. For example:

If you know the sewer segment has concerns and has bends in it, then 3D LIDAR may be desirable as a means of mapping the sewer.

If blockages are your concern, acoustic rapid assessment may be a good starting point to help narrow the focus on runs where you want to perform further evaluation.

If you have seen evidence of corrosion in manholes and have a concrete pipe, an H2S sensor may be in order.
If you want information on the whole pipe and cannot bypass the flows, you will need to supplement a technology like CCTV with sonar in order to see below the water surface.

When defining your goals, be sure to solicit the input of all levels of staff and the ways they can benefit from the data.

2. Consider combining technologies to address different needs.
Each tool described here has strengths and limitations, so no technology is perfect for all conditions. Laser profiling and sonar can be combined to get thorough data above and below the water surface. An acoustic assessment can be used as a preliminary method in order to identify any blocked pipes that require more detailed assessments. An H2S gas sensor may be needed for pipes that may have corrosion, but you may have pipes of varying material throughout your system and may not need to pay for this technology everywhere. By working with a knowledgeable consultant, you can customize a plan using several different technologies only where they are needed in order to maximize the use of your budget resources.

3. Recognize that special equipment availability may affect your schedule.
Specialized equipment is not as readily available as basic equipment, so, if quick turnaround is necessary, you may want to plan your schedule around any specialty equipment needs.

4. Understand the sewer material being investigated.
If the sewer is concrete, corrosion is a real concern, so an H2S gas sensor or laser profiling may be needed. (This is not the case if the sewer is vitrified clay.)

5. Consider the ground surface.
Is there evidence of settlement on the surface near sewer lines? If so, perhaps in-pipe GPR should be considered to look for voids that have developed around the sewer.

6. Recognize your flows.
Some of the tools described here have specific water flow requirements. For example, CCTV and laser profiling require head space above the water to be effective, but sonar needs a certain depth of water over the bottom of the sewer (as well as any debris present) in order to be successful. Therefore, you will need to coordinate with appropriate staff to implement a means of controlling the flow of water through these lines.

Water flow also impacts the types of vehicles used to carry the various tools through the sewer. Depending on your flows, a crawler may work well, or a float platform may be more suitable. Wheels can be put on float platforms, so additional space is needed for clearance.

7. Plan for the unexpected.
As much as you try to consider every goal and every possible need, each job involves surprises. (If you knew exactly what you’d find in the pipes, you wouldn’t need an inspection, after all, would you?)

That’s why you should design a plan that is flexible for changing circumstances and build extra time into your schedule. Decide ahead of time what will be done if a buried manhole or substantial debris is found: Will you uncover the manhole now? Will you clean the debris out right away or just note it in the report?

The vehicles carrying the inspection tools can often travel thousands of feet if there are no drops or other concerns, so you may not need to access every single manhole during a condition assessment. However, you should still have a method in place for identifying each manhole in case needs change. (Also, individually identifying each manhole – even those not uncovered for access – is essential for logging the findings of your assessment in a report.)

Develop IDs for every manhole – even those you don’t plan to access — prior to inspection and have a plan for how to ID structures if one is found during the investigation. This can reduce confusion and make post-processing more efficient.
A thorough assessment of the condition of your sewers is crucial to optimizing system performance, determining maintenance and repair needs, and budgeting for the eventual replacement of aging infrastructure. It can also help you discover problems before they result in a system failure or reduced service to your customers. While inspections can cost thousands of dollars, they can save you thousands more if they prevent a sewer main backup or break (and the associated costs to repair the sewer and other infrastructure the break may have damaged). They also help you better target your cleaning and maintenance efforts to where the work is needed most.

In determining which technology to use for a condition assessment, you need to consider the materials of your pipes and the volume of flows through them, the goals you plan to accomplish, and your timeline for completing the work. Some tools like a zoom camera or acoustic assessment provide quick data but may need to be supplemented with other methods if blockages are found or more detail is needed. Other tools like laser profiling and CCTV will only provide data on the condition of pipes above the water line, so additional technologies like sonar will be needed to assess the pipes below water level. Some technologies like 3D LIDAR and gyroscopic mapping provide a high level of detail that may be necessary for certain specialized cases.

The figures above illustrate some meaningful findings from a condition assessment. The “shape” of the pipe resulting from sonar and laser profiling is compared with the design shape of the pipe in the figure on the left, indicating helpful information such as debris and uncovered manholes (the red spots). The quantity and distribution of debris as shown in the figure on the right will help in developing bidding documents for a cleaning project and getting better prices.

 

In order to provide the best possible data at an optimized price, it is wise to seek the counsel of an experienced professional who can customize a plan that uses several different technologies based on the varying conditions throughout your system.

With the right tools, you can ensure you get the data needed to keep your system functioning at optimum levels for all your customers for several years to come.
