EBMUD continually invests in our critical infrastructure to ensure the water and wastewater services you depend on remain safe, reliable and affordable. Whether it’s managing water supplies now and for the future, upgrading water treatment plants so every drop you drink is of the highest quality, replacing aging pipelines that deliver water to your taps, or improving the wastewater system that protects your health and the environment, we’re always in action to meet our community’s needs. This work across our interconnected systems benefits all 1.4 million EBMUD customers.
Here are a few of the dozens of essential infrastructure projects underway to serve you better.
-
Aqueduct Relining
EBMUD’s Mokelumne Aqueducts convey 90 percent of our water supply from the Sierra Nevada foothills to the East Bay. We will be repairing and relining sections of these 90-mile-long steel pipelines to improve structural integrity and water supply reliability. Status: In design; construction in 2029-2032.
-
Orinda Water Treatment Plant Upgrades
This multiyear project will improve water treatment disinfection, reliability, and resiliency against water quality fluctuations caused by climate change. EBMUD’s largest water treatment plant serves approximately 800,000 customers. Status: Construction in progress; completion in 2028.
-
Pipeline Rebuild
Replacing aged distribution pipelines before they break reduces water loss, customer outages, and potential damage to assets and the environment. EBMUD takes a strategic approach. We plan to replace nearly 300 miles of pipeline over the next decade. Status: Ongoing in multiple locations.
-
Wastewater Infrastructure
Most of our wastewater infrastructure was built 50-70 years ago and needs renewal. Wastewater pipeline repairs, structural retrofits, and equipment replacement will improve safety and reliability while reducing long-term maintenance costs. Status: Construction in 2025-2031.
