Building the Capacity of Drinking Water Systems

Learn about Capacity Development

More than 97% of the nation’s 156,000 public water systems are small systems, meaning they serve 10,000 or fewer people. A public water system (PWS) is a system that provides water for human consumption to at least 25 people or 15 service connections.

PWSs include:

  • Municipalities
  • Small towns
  • Homeowners associations
  • Other kinds of facilities like schools, restaurants or campgrounds

Small water systems can face unique financial and operational challenges in consistently providing drinking water that meets EPA standards and requirements. EPA works closely with states and our federal and tribal partners to assist small systems with financial and technical resources to sustainably provide safe drinking water.

Learn about Small Drinking Water Systems

Capacity Development is a process for water systems to acquire and maintain adequate technical, managerial and financial (TMF) capacity. TMF capacity enables water systems to have the capability to consistently provide safe drinking water to the public.

What is Capacity Development?

Capacity development is a fundamental component of the 1996 Safe Drinking Water Act (SDWA) Amendments. The SDWA Amendments provide a framework for states and water systems to work together to protect public health. Every state has developed a Capacity Development Program to assist public water systems in building TMF capacity.

Any water system can implement capacity development activities to increase their TMF capacity. Small systems can especially benefit from capacity development. EPA is committed to helping small water systems provide safe drinking water through publications, training, and technical and financial assistance.

Local officials and consumers play an important role in helping small water systems meet regulatory requirements and protect public health. Besides protecting public health, communities that support their water systems are making long-term investments in sustainable communities and economic well-being.

History of the Capacity Development Program

The Capacity Development Program was created under the Safe Drinking Water Act (SDWA) Amendments of 1996. The three major components of the Capacity Development Program are:

1. Section 1420(a) New Systems

Under penalty of Drinking Water State Revolving Fund (DWSRF) withholding, States must have a program established to:
"ensure that all new community water systems and nontransient, noncommunity water systems commencing operations after October 1, 1999 demonstrate technical, managerial, and financial capacity with respect to each national primary drinking water regulation in effect, or likely to be in effect, on the date of commencement of operations."

2. Section 1420(c) State Capacity Development Strategies

Under penalty of DWSRF withholding, the State must develop and implement a:
"strategy to assist public water systems in acquiring and maintaining technical, managerial, and financial capacity."

3. Section 1452(a)(3) Assessment of Capacity

States may not provide DWSRF loan assistance to systems

  • which lack the technical, managerial, and financial capability to ensure compliance; or
  • if the system is in significant noncompliance with any drinking water standard or variance.

However, States may provide assistance if:

  • the use of such assistance will ensure compliance; and
  • the system has agreed to make the necessary changes in operation to ensure that it has the technical, managerial, and financial capacity to comply over the long term.
