Project improves access to regional water supplies and supports a strong local economy

Reliable water supports daily life in Roseville, from homes and schools to businesses and emergency services. New federal funding is helping Roseville build a resilient water system that supports daily needs, a strong local economy, and long-term reliability.

With this funding, Roseville can move forward on a regional water reliability project that provides direct access to the Placer County Water Agency’s Middle Fork Project. The 14-mile pipeline will connect the Middle Fork water supply to the Barton Road Water Treatment Plant (WTP), improving flexibility during dry years and emergencies when Folsom Lake water is not available. Up to $5.3 million will support early planning, design, and environmental review.

With more than 150,000 residents and continued growth, Roseville relies on a reliable water supply to support daily needs and the local economy. Planning ahead improves preparedness for drought, emergencies, and changing conditions.

When complete, the new pipeline will initially deliver up to 10 million gallons of water per day to Roseville, reducing reliance on a single intake and strengthening the overall system.

Folsom Lake will remain an important regional water resource, supporting water supply, flood protection, water quality, and the Delta. However, lake levels can change significantly from year to year.

Today, Roseville relies on a single surface water intake at Folsom Lake, an aging piece of infrastructure with no redundancy. If that intake cannot be used, the city loses access to its surface water supply. In extremely low-water conditions, that intake could become less reliable. The new pipeline provides a critical upstream backup, improving system reliability during the most challenging conditions.

“This project is about planning ahead and making sure our community has reliable water no matter what ...”

“Reliable water supports everyday life, and a strong local economy, from homes and schools to businesses and healthcare, and this funding allows us to take the first steps to keep Roseville growing safely and responsibly.”

PCWA leaders emphasized the broader regional benefits of the partnership.

“Water reliability is a shared responsibility across Placer County ...”

“By working in partnership with Roseville to create direct access to our water supply, we’re strengthening regional water reliability and flexibility while supporting public health, economic stability, and resilience during dry years.”

The initial federal funding supports early project work to ensure the pipeline is planned carefully and responsibly before construction begins. Additional steps and future funding will follow as the project progresses.

Alongside local water reliability, the project benefits the region by decreasing pressure on a single water intake, helping maintain environmental flows, and ensuring water remains available for downstream uses, even in the driest of years.

By investing early and planning responsibly, Roseville and PCWA are building a water system that supports community health, economic stability, emergency readiness, and long-term regional growth.
