Document Description
LADWP proposes to modernize the potable water distribution system by replacing all aging and deteriorated pipelines that are part of the City’s regional trunk line system. The Proposed Program aims to replace, as necessary, trunk lines and connections with the appropriate pipe material and size and upgrade appurtenances to ensure safety, reliability, and redundancy of the system. Using data and field assessments, LADWP strategically prioritizes the replacement of aging infrastructure and chooses the trunk line alignments based on numerous factors. The Proposed Program aims to ensure continued safe and reliable transportation and distribution of potable water to its customers throughout the City for residential, industrial, and firefighting purposes. Under the Proposed Program, six trunk line replacement projects have been identified as priority projects. The Proposed Program is expected to be implemented through the planning horizon year 2056, with the six priority projects occurring in the near term (within the next 10 years).
