The program is a long-term effort to replace aging water pipelines throughout Los Angeles. These larger pipelines, known as trunk lines, transport and distribute water across the city. Many are more than 100 years old, and replacing them will help improve water service reliability, reduce the risk of major water main breaks, and strengthen our overall water infrastructure.
At this stage, LADWP is beginning the environmental review process, not construction. This process is conducted in accordance with the California Environmental Quality Act (CEQA), which requires public agencies to evaluate potential environmental impacts before approving certain projects. As part of this process, LADWP has issued a Notice of Preparation and established a public comment period from November 6 through December 11, 2026. This allows community members to identify potential concerns, such as traffic, noise, construction impacts, and neighborhood access, early in the planning process before the Draft Environmental Impact Report is prepared.
The upcoming virtual public scoping meetings will provide an overview of the program, explain the environmental review process, and allow community members to share their input.
Public Scoping Meetings:
Tuesday, November 17, 2026, at 11:00 a.m.
Tuesday, December 1, 2026, at 6:00 p.m.
Additional project information, including the locations of the six priority projects, is available here.
