Emergency water supply: The Upper Chiquita Reservoir
The Upper Chiquita Reservoir in southeastern Orange County, California, was built to provide substantial water reserves to meet customer demands during disruptions of water deliveries. The reservoir's design is impressing if only because its depth of almost 49 metres. So it is one of the deepest reservoirs in the US. The reservoir's goal is to provide more than 908.5 million litres of water to serve approximately 170,000 families at 750 litres per day for a week. In the project's design, site security and water conservation were critical. To maximize performance, a geomembrane base liner and floating cover were designed with an emphasis on longevity placed on the cover membrane. More than 72.840 m2 of liner were installed to provide the essential containment. For the slope and the base liner, a 60-mil polypropylene geomembrane was used because the PP liner's service life is extended by the absence of UV degradation. The floating cover is a 60-mil, three-ply CSPE geomembrane. The cover alone uses more than 83,600 m2 of geomembrane. The article describes the installation procedures. As there were serious concerns with the reservoir's siting from an aesthetic standpoint, the designers took care to disguise the reservoir in the hill. Revegetation for the surrounding environment began at the end of 2011.
