Climate Action: Mayor Bass, City Leaders Open New Groundwater Treatment Facilities to Restore Up to 43 Million Gallons of Contaminated Groundwater Daily into Safe Drinking Water
On August 24, Mayor Karen Bass joined Councilmember Adrin Nazarian, LADWP officials, state and federal regulators, and community leaders to celebrate the completion of the North Hollywood Central and North Hollywood West Groundwater Treatment Facilities. The completion of these facilities represents a major milestone in remediating the San Fernando Basin and strengthening Los Angeles’ climate resilience. These facilities directly advance Mayor Bass’ Climate Action Plan, which sets ambitious targets for climate resilience and water sustainability, including reaching a 70% local water supply by 2035.
The facilities are part of LADWP’s San Fernando Valley Groundwater Remediation Program, one of the City’s largest investments in local water infrastructure. The program includes three treatment facilities: North Hollywood Central, North Hollywood West, and Tujunga, which will be completed by 2027. Collectively, these facilities will have the capacity to extract and treat roughly 92 million gallons of water per day, enough to supply up to 400,000 L.A. homes a year. The North Hollywood Central and North Hollywood West facilities alone can treat up to 43 million gallons of groundwater each day.

Mayor Bass and Councilmember Monica Rodriguez Join LADWP Leadership to Celebrate Major Seismic Water Infrastructure Milestone in the San Fernando Valley
Mayor Karen Bass, Councilmember Monica Rodriguez (Council District 7), President of the Board of Water and Power Commissioners Allan Marks, and Interim LADWP General Manager David W. Hanson gathered at LADWP’s Sylmar WEST training facility on August 27 to celebrate the full installation of the largest and longest large-diameter Earthquake Resistant Ductile Iron Pipe (ERDIP) in the nation. As part of the Foothill Trunk Line project, crews installed more than 22,000 feet or approximately 4 miles of seismic drinking water pipe designed to withstand earthquakes and help ensure long-term water reliability. The final trenchless tunneling phase will proceed over the coming year, with full project completion expected by 2032.
This milestone is part of LADWP’s ongoing capital infrastructure plan, launched over a decade ago to prioritize system resiliency and reliability. After initial ERDIP testing in 2013, LADWP pioneered one of the nation’s first ERDIP pilot deployments at Northridge Hospital Medical Center, near the epicenter of the 1994 earthquake. This installation demonstrated that flexible joints could protect vital community assets during severe ground movement, laying the foundation for a citywide strategy that continues to expand.
The strategic deployment of ERDIP applies to both proactive replacement and long-term master planning following major incidents. For example, following the trunk line break in West Hollywood in July, emergency repairs were completed immediately, while design plans continued for comprehensive multi-mile permanent replacement using earthquake resilient pipe.
Since the Earthquake Resistant Pipe (ERP) program began in fiscal year 2012-2013, LADWP has installed 67.2 miles of ERP mainline and trunk line pipes (43.2 miles of mainline and 23.9 miles for trunk line), with more projects planned at strategic locations throughout the city. In the 2025-2026 fiscal year alone, crews installed over 3,700 feet of trunk line pipe and over 244,000 ft of mainline pipe.

Let the Water Flow: Recycled Water Fill Stations Open for the Season
LADWP relaunched the Recycled Water Fill Station program (RWFS) on August 21. The program offers LADWP residential customers up to 300 free gallons of recycled water per visit, which can be used on landscaping, such as trees, shrubs, gardens, and lawns. Recycled water can also be used for the irrigation of edible fruits, vegetables, and herbs, provided they are washed with drinking water before consumption. The most important benefit of the RWFS program is that recycled water helps support the conservation of drinking water. Using recycled water for landscaping purposes allows the Department to offset the use of precious drinking water.
In 2025, LADWP supplied 35,560 gallons of free recycled water to nearly 200 customers as part of the program, which helped make L.A. that much more sustainable. Participation is easy and only requires an LADWP bill, a government-issued ID and water-tight containers to fill at the stations. To ensure proper use, customers must also attend a brief, five-minute on-site training, and submit a signed application and agreement form. Safety stickers are provided to mark the containers as recycled water only, not suitable for drinking.
Two stations were opened for customer convenience. The first is at the Los Angeles-Glendale Water Reclamation Plant, located at 4600 Colorado Blvd. and open every Friday from 8:00 a.m. to 3:00 p.m. The second station is at Delano Park, located at 15100 Erwin St. in Van Nuys. This station is open every Thursday from 8:00 a.m. to 3:00 p.m. Employees who are also LADWP customers are encouraged to participate.

LADWP Hosts LA100 Advisory Group Kickoff Meeting
In August, Power System’s Planning & Innovation Division kicked off the LA100 Plan Advisory Group, bringing together 49 organizations, including academia, business and workforce groups, city government, community-based organizations, environmental community, neighborhood councils, and utilities, to guide Los Angeles’ transition to 100% clean energy. The meeting was held at The Beehive in South LA, a vibrant and modern gathering space in the heart of Los Angeles that reflects the energy and innovation behind the city’s clean‑energy future.
The LA100 Plan, formerly the Strategic Long-Term Resource Plan (SLTRP), is LADWP’s long‑range roadmap for delivering reliable, affordable, and sustainable electricity while transitioning Los Angeles to 100% carbon‑free energy by 2035. Updated every two years, the plan uses rigorous analysis and extensive community engagement, guided by the LA100 Advisory Group.
The project team provided a comprehensive overview of the LA100 goals, including detailed projections, resource planning scenarios, grid reliability assessments, and the extensive technical work completed to prepare the city for large‑scale renewable integration. The presentation underscored the long‑term strategies required to build a resilient, clean energy grid and the operational challenges involved. The kickoff meeting set priorities for equity-focused strategies, renewable integration, and collaborative planning to support a resilient, sustainable future for all Angelenos. The meeting highlighted the importance of collaboration between LADWP and local partners to build trust and maintain open communication throughout the transition.
As the first stakeholder meeting in this cycle, the kickoff established momentum for the Advisory Group’s future discussions and recommendations, reaffirming Los Angeles’ commitment to an inclusive path toward 100% clean energy.
