Smart Capital Planning for Water and Wastewater Utilities

For a waterworks system to ensure reliable, long-lasting services, it’s critical that a fundamental component be efficient resource allocation. By incorporating capital efficiency plans, master plans, and a methodical capital planning process, utilities are able to navigate the complexities of their industry, not only by enabling them to strategically allocate resources and address dire infrastructure needs but also by meeting the persistent demands of evolving environmental regulations.

As we forge ahead, smart capital planning remains the compass that guides utilities towards a future where access to clean water is not just a necessity but a sustainable and well-managed reality.

Capital Efficiency Plans (CEPs): The Blueprint for Resource Organization

Capital Efficiency Plans (CEPs) at T&H follow a standard Venn diagram method. For every water main segment, there are three sets of evaluation criteria: key components, asset management, and hydraulic modeling.

With each set comes its own set of unique drawbacks, and it’s where the three overlap that the system’s weak points are put on display. If it seems that the weaknesses meet more than one set of criteria, then they are swiftly prioritized above the others as they require the most attention. By choosing this type of visual method, CEPs can quickly and justifiably pinpoint areas of criticality, allowing utilities to make a targeted plan of attack.

To put it simply, CEPs are a vital element of smart capital planning because they provide utilities with a strategic roadmap leading them towards the treasure trove of resource optimization. CEPs prioritize resource allocation by identifying the projects that will offer the greatest impact on efficiency (in other words, the ones that require the most attention), while also evaluating any potential risks such as regulatory changes and environmental challenges.

By streamlining capital investments, utilities can ensure cost-efficiency while also maintaining and improving their service standards and mitigating any potential, unforeseen issues.

Master Plans: The “What, When, and How” for Sustainable Development

A water master plan is essentially what it sounds like: a blueprint for sustainably managing and using water resources within a specific region. Diving deeper, a water master plan is a detailed framework that takes a variety of factors into account, like evaluating the current water supply, demand forecasts, infrastructure development, conservation tactics, financial planning, and environmental impact evaluations, to name a few.

Water, after all, is our lifeblood; without it, we could not sustain ourselves, our ecosystems, or our industries. It’s no secret that water utilities are often the ones on the front lines battling mitigation efforts, a lack of funding, and a complex web of other responsibilities. This juggling act often means that they need to know the “what, when, and how” as soon as possible: what do they need to do? When do they need to do it? How are they going to pay for it?

A water master plan has three main components: infrastructure assessment, data collection and analysis, and long-term goals. The first step is an infrastructure assessment that will evaluate the current water systems and infrastructure, including a review of pipelines, treatment plants, distribution networks, storage facilities, etc. This comprehensive evaluation will also be able to identify any infrastructure needs, such as maintenance, upgrades, or expansions.

The second step in any effective master plan is data collection and analysis. The master plan is constructed by using the initial assessment’s findings as its foundation—everything from demographic trends to industry developments can provide crucial information that can lead the plan down the path of success or failure. This step is important because it will influence the master plan. After all, bad data equals bad resource allocation. Thirdly, water master planning needs to extend far beyond the immediate needs; long-term goals are absolutely critical in ensuring the future of sustainable water management and utilization.

The heart of a water master plan is straightforward: ensure that water resources are allocated fairly, address critical issues like population growth and climate change, and establish a robust, accessible, and dependable water delivery system. Because at the end of the day, a water master plan promotes long-term water security, the health of people and ecosystems, and effective water management by integrating technical, economic, and environmental concerns.

Capital Planning

Utilities use the capital planning process, a structured methodology, to identify, prioritize, and allocate resources for capital projects. By addressing present demands and preparing for upcoming obstacles, this strategy helps utilities to align investments with strategic objectives. It starts with a thorough evaluation of the state of the infrastructure, which paves the way for the identification of priority projects that solve short-term issues and support long-term objectives.

An essential part of the planning process is estimating the price of proposed capital projects. Utilities use financial analysis to evaluate project viability and pinpoint possible funding sources, and a detailed risk assessment is carried out in order to identify and minimize any issues that could affect the success of capital projects. Investment resilience is increased by proactive risk management.

A financial analysis can help utilities determine just how feasible their projects are and aid in the search for funding by assessing their weaknesses in order to foresee any challenges that could impact the project’s success. Important stakeholders are then consulted to ensure the process takes into account a variety of viewpoints and community requirements. This cooperative and collaborative strategy not only promotes transparency, but it also has the power to greatly increase stakeholder trust.

Conclusion

In the face of a constantly evolving environment while meeting complex regulatory and social dynamics, there is no denying that smart capital planning is essential for the sustainable development of water and wastewater utilities. To put it succinctly, in order to have sustainable development, management, protection, and distribution of water and wastewater utilities, extensive planning is non-negotiable. Combined with ever-changing technology, utilities are further empowered to adapt and thrive.

By incorporating capital efficiency plans, master plans, and a methodical capital planning process, utilities can navigate the complexities with far more ease and effectively meet the needs of their communities.

Meeting Wastewater Utilities’ Needs Through Capital Efficiency

restrooms-300x200Wastewater. It’s something that will always exist, and will always require collection and treatment. Just like improved water, improved sanitation is one of the key contributing factors to a developed nation, significantly improving public health, educational opportunity, and workforce viability. And while the United States boasts nearly 100% improved water and sanitation, there is still cause for concern.

In the American Society of Civil Engineers (ASCE) 2013 Report Card, wastewater received a “D” grade. Why? Because our existing infrastructure is in desperate need of repair and replacement, and a significant funding gap exists. This gap can be attributed to the fact that funding has been declining while regulations continue to increase.

Pic1-TotalPublicSpending-300x200In March of 2015, the Congressional Budget Office (CBO) published a report on annual government expenditures on infrastructure, titled Public Spending on Transportation and Water Infrastructure, 1956 to 2014. The data, collected from the Office of Management and Budget (OMB) for federal expenditures and from the Census Bureau for state and local government expenditures, indicates that federal, state, and local governments in the United States have been investing LESS in water and wastewater infrastructure than ever before. From 1956 to the late 1980s, total government spending increased in real dollars by approximately 3%-4% per year, and then from 1%-2% through 2009. These expenditures include both capital and operations and maintenance (O&M) costs. However, from 2010 until present, total government spending has actually decreased by 8%.

Pic3-OMvsCapital-300x200To further complicate matters, capital expenditure has decreased at a faster rate than O&M expenditure. From 1956 to 1980, public spending was basically split between capital expenditures — to build or replace water and wastewater systems —  and O&M of the systems. However, since 1980, O&M spending continued to grow at an annual rate of 4%-6% to the 1990s, and then at an annual rate of 1%-3% through 2009, since when it has remained flat. In contrast, capital spending grew at an annual rate of only about 1%-2% since 1980, and has declined at an average annual rate of 4% since 2009. Governments now spend twice as much on O&M of their existing systems than on capital expenditures to repair, rehabilitate, or replace existing assets or for the installation of new infrastructure. In addition, state and local government is now saddled with nearly the full burden of capital expenditure, as federal spending has been steadily on the decline since 1976.

Clearly, municipalities are faced with the almost insurmountable task of staying up to date with all current regulations while also improving outdated and failing systems. Because wastewater collection and treatment is such a crucial aspect of modern day society, it has become paramount that municipalities find cost-effective and efficient ways of maintaining and updating critical infrastructure.

One of the most effective ways in which municipalities can intelligently allocate their limited infrastructure dollars is by implementing a clear and systematic plan of action for capital improvement projects. Typically, asset management is considered to be the standard by which wastewater utilities address capital assets. Defined by the EPA as managing infrastructure capital assets to minimize the total cost of owning and operating them, while delivering the service levels customers desire, asset management certainly plays a key role in smart capital planning. However, asset management should only be part of the equation. Hydraulic modeling and system criticality are two equally important aspects which should be examined when planning long-term capital expenditure.

Tata & Howard’s Wastewater Capital Efficiency Plans™ identify those areas of your wastewater systems needing rehabilitation, repair, or replacement that make the most efficient use of your limited infrastructure dollars by combining the concepts of hydraulic modeling, system criticality, and asset management into a single comprehensive report. Each report is tailored to the individual utility distribution system and provides utilities with a database and Geographic Information System (GIS) representation for each pipe segment within their underground piping system. The CEP report then prioritizes system piping improvements and provides estimated costs for replacement and rehabilitation.

Our three circle approach includes the following:

Three Circles WASTEWATER 515-finalHydraulic modeling

  • Model verification if available
  • Compare flows with design carrying capacity
  • Hydraulic deficiencies
  • History of SSOs
  • High infiltration/inflow rates

Critical Components

  • Interceptors
  • Trunk sewers and force mains
  • Residential sewer mains

Asset Management

  • Establish score for each pipe segment based on blockages/collapses, I/I rates, installation year, soil corrosivity, PACP structural and maintenance ratings, and other criteria.

A comprehensive CEP provides a utility with not only a prioritized list of logically thought out infrastructure projects, but also a justifiable and defendable plan of action to present to town administrators when planning budgets.

Manhole_cover_sewer_closeup-300x200To continue as a leading industrialized nation, our wastewater utilities must not only remain safe and functional, but also progressive and up to date with current and future regulations. Because funding is declining while costs and population are increasing, it is more important than ever for wastewater utilities to methodically prioritize and plan all repairs and improvements. Only through the implementation of a well-researched and systematic course of action will utilities be prepared to provide safe and dependable wastewater services both now and in the future.
