Hauck Mesa Storage Reservoir

Project Background

Hauck Mesa Storage Reservoir Improves Regional Water Deliveries

The Water Authority’s First and Second Aqueducts deliver treated and untreated water throughout San Diego County while the Valley Center Pipeline and Pump Station facilitate treated water deliveries between the two aqueducts. The pump station boosts water from the Second and First Aqueducts to serve the Valley Center Municipal Water District, Vallecitos Water District, Vista Irrigation District and Rincon del Diablo Municipal Water District.

The existing aboveground storage reservoir at Hauck Mesa in Valley Center will be replaced to provide treated water storage along the First Aqueduct. The new storage reservoir will enhance the Water Authority’s ability to provide reliable and efficient deliveries of treated water to member agencies. Construction is expected to last approximately two years and is anticipated to be complete in 2022.

New flow regulatory structure to enhance service reliability

The Hauck Mesa Storage Reservoir project will construct a new, above ground water tank, or flow regulatory structure, on the Valley Center Pipeline to enhance service reliability. The reservoir will help eliminate pump station surge and outage events and provide operational flexibility by balancing treated water flows between the First and Second Aqueducts. The work includes the demolition of an abandoned welded steel tank, removal of soil, and the construction of a 2.1 million gallon treated water reservoir, valve vault and flow control facility to regulate water flows.
