Irvine Lake Pipeline Conversion Project

Irvine Lake Pipeline Conversion Project

The Irvine Lake Pipeline Conversion Project will transform the northern portion of IRWD’s Irvine Lake Pipeline from an untreated water system to a recycled-water system. Contractors are constructing a buried concrete reservoir off of Santiago Canyon Road and installing 42-inch-diameter recycled-water pipelines under Santiago Canyon Road and Jamboree Road.

Once complete, the system will deliver recycled water to Orange and northern Irvine, primarily for landscape irrigation. This project is part of the IRWD strategic plan to increase recycled water use and reduce reliance on imported water. Every gallon of recycled water used frees up a gallon of drinking water for homes and businesses.

Roadwork will affect traffic for several months in 2018. Details below
