City crews are preparing to install a new pipeline in Miramar Reservoir — the final segment of a project that will transport water from the North City Pure Water Facility to Miramar Reservoir through eight miles of pipeline.

This is a critical component for the Pure Water Program — the city’s effort to use purification technology to clean recycled water and produce safe, high-quality drinking water for San Diegans. Over one mile of branched pipeline is currently being assembled on the shore, and it will then be loaded onto barges and moved to its permanent home underwater.

The Miramar Reservoir pipeline is one of 12 current projects in Phase 1 of the Pure Water Program, expected to be completed in 2025. It will aim to provide 30 million gallons of clean water daily.

During construction, land activities — including shore fishing — will be permitted, but in-water activities are on pause.
