Public Utility Districts provide water and water-sewer service in communities across the state, often specializing in rural and “satellite systems.”

Public utility districts collectively serve more than 125,000 water customers. Through the years, primarily because of deteriorating infrastructure and regulations imposed by the Federal Safe Drinking Water Act, owners of small water systems have asked PUDs for help. Acquiring and upgrading water and wastewater systems is expensive and challenging, but necessary for the people served by PUDs. As with all PUD services, water and wastewater service is provided on a not-for-profit basis, reflecting the actual cost of service.


The majority of PUD water systems were originally community water systems that couldn’t be maintained by their owners and customers and were voluntarily turned over to the local PUD. Many water systems acquired by PUDs are 50-plus years old and in need of major improvements. PUDs often depend on state and federal grants and low-interest loans to finance these improvements and keep rates for customers as low as practical.

The Washington PUD Association works closely with the state Health and Ecology Departments and the federal Environmental Protection Agency on regulatory relief for PUDs providing water services. In addition, WPUDA works with the Legislature on state water law reforms that will help PUDs provide safe and efficient water service.  WPUDA also provides assistance to PUDs in seeking state and federal grants for water system improvement projects.

WPUDA played a key role in passage of Washington’s Municipal Water Law in 2003, which, among its provisions, defines “municipal water suppliers” as public and private water utilities that serve 15 or more residential connections and protects the validity of numerous water rights held by water utilities serving homes and businesses across the state.
