A pilot project from LADWP that uses an innovative technology called “Aqua Pipe” was the subject of a recent NBC feature story. View it here.

Newly deployed by LADWP, this trenchless technology was used to build a new, permanent pipe inside of a leaky 550’ section of cast iron water main constructed in the 1960’s. The new pipe is a composite of woven textile and hardened epoxy with an internal polyurethane membrane that will last 50 or more years after the original pipe is no longer functional.

Using this “trenchless” technology meant that LADWP crews didn’t have to tear up the residential street along the length of the pipe. It also minimized construction impacts like dust, noise, vibration, and traffic delays while cutting construction costs by 30% and greenhouse gas emissions by 85%.

This technology gives LADWP a cost effective and environmentally friendly new tool to rehabilitate degrading pipelines near the middle of their expected useful life. This strategy also complements LADWP’s aggressive goal of replacing more than 520 miles of pipe over the next decade. These collective efforts are critical investments that will help reduce leaks dramatically to enable more water conservation and cause fewer service disruptions for our customers.
