San Joaquin Reservoir Filtration Facility
Irvine Ranch Water District contractors began work in March 2023 on a project to improve water filtration at the San Joaquin Reservoir, which provides recycled water for landscape irrigation and other uses in Newport Coast and parts of Irvine.
The project calls for the construction of a new building, facility electrical system, and the installation of a new filtration system inside the building. (See area marked in blue on the map.) A new underground pipeline will be installed along the reservoir access road from the new building to the south side of the reservoir. (See area marked in red on the map.)
A temporary staging area has been set up at the south end of the reservoir to store equipment and materials. That area will be cleared once the project is completed. Also, to ensure access to the reservoir site for larger vehicles, temporary parking restrictions may be periodically set up along Ford Road. Motorists are advised to comply with temporary no parking signs posted during these periods.
What: Construction of a new water filtration facility (blue area) and a new underground pipeline (red area)
When: March 2023 to September 2025
