The LADWP Water System is the largest municipally owned and operated retail water utility in the country. Its mission is to provide customers with reliable, high quality and competitively priced water services in a safe, public, and environmentally responsible manner.
The Water System’s Capital Improvement Program is a ten-year plan focused on maintaining or replacing existing components of the Water System, and constructing new facilities to ensure LADWP fulfills its mission of providing reliable and high quality water to the residents of Los Angeles.
Many facilities pre-date World War II and are near the end of their useful lives. In addition to aging infrastructure, existing and anticipated changes in state and federal water quality regulations affect the way LADWP stores and treats water that arrives at the tap. LADWP is responding to these changes and improving its water quality by eliminating dependence on large in-city open reservoirs. LADWP is also instituting more comprehensive monitoring programs to ensure that the water delivered is the highest quality and meets all state and federal drinking water regulations.
Our Capital Improvement Program is divided into four major sections:
- Infrastructure Reliability
- Water Supply
- Regulatory Compliance
- Other Strategic Activities
LADWP has developed the Water Infrastructure Plan to establish the goals and targets for replacing and/or upgrading infrastructure.
