Investments In Your Community Water System
Long-Term Infrastructure Reliability
It will cost $425 million over 25 years to accomplish long-term infrastructure reliability, according to an independent analysis of the Agency's water system completed in 2021.
As a community-owned water system, these investments ensure reliable service for the customers PCWA serves.
In 2022, the Agency adopted a rate increase, effective in 2023, to address the ongoing need to renew and replace aging infrastructure. The new rates will provide an average annual revenue stream of $17 million dedicated to this effort.
In 2025, $17.7 million was invested through PCWA's Renewal and Replacement Program. This program helps ensure the system's reliability and sustainability for existing and future customers.

Renewal & Replacement Project Highlights
This new 2 million-gallon-per-day water treatment plant will replace the existing 1.2 MGD facility, which is nearing the end of its operational life. The new plant will be built at a different site and designed with the capacity to expand to 3 MGD, allowing for future consolidation of smaller water systems in the region, including Shady Glen, Applegate, and Weimar.
- The new water treatment plant replaces the old plant, which requires significant maintenance.
- It improves access to the agency treated water system and the overall treatment process.
- As part of the regionalization effort, it supports future consolidation of nearby water systems.
Consolidation Project
Shady Glen Community Water System Consolidation
Funding for this project comes from State Water Resources Control Board grants and water connection charges. State funding has supported design, environmental review, construction, water connection charges, and project management activities.
"Funding for this project has been provided in full or in part under the Budget Act of 2021 through an agreement with the State Water Resources Control Board. The contents of this document do not necessarily reflect the views and policies of the foregoing, nor does mention of trade names or commercial products constitute endorsement or recommendation for use."
Install 1,700 linear feet of 18-inch pipeline to support consolidation of the Shady Glen Community Water System and improve regional water transmission.
The new pipeline serves dual purposes: connecting the Shady Glen system, which provides service to 121 residential connections, and functioning as a transmission main for the future Colfax Water Treatment Plant replacement. This upgrade is designed to enhance system reliability, improve water quality, and support long-term regional water planning.

Water Challenges
Water Delivery Challenges: Lake Spaulding
In 2024, and again in 2025, PCWA faced significant challenges due to damage to Pacific Gas and Electric Company's (PG&E) outlet infrastructure at Lake Spaulding. This issue reduced water releases into Rollins Reservoir, a primary source for PCWA's water system, and impacted water deliveries throughout the irrigation season.
