Turtle Rock Reservoir and Pump Station Project

Irvine Ranch Water District is planning improvements to its Turtle Rock Reservoir and Pump Station on Minaret, which provides safe and reliable drinking water to the community.
The project includes plans to improve and maintain water quality in the reservoir with upgrades that will include a new building for water disinfection and a mixer system to maintain the highest level of water quality in the reservoir. This structure will be located on IRWD's property, southeast of the existing building.
When: March through December, 2023
Construction hours: 7 a.m. to 3:30 p.m., Monday through Friday

As a part of this project, the gated entry to the facility will be widened for improved access to the site, and the existing chain link gate will be replaced with an onamental steel gate. A new security fence will be installed across the reservoir acces road to address community concerns about trespassing on the reservoir access road at night.
IRWD has worked with the homeowner's association to ensure that the improvements blend with the surrounding community and maintain the aesthetics of the neighborhood, including providing additional trees to help screen the improvements.
