2017 CASQA Award Winner - Outstanding Retrofit Sustainable Stormwater Project: Los Amigos Park Stormwater Harvesting and Direct Use Demonstration
The Los Amigos Park Stormwater Harvesting and Direct Use Demonstration project taps into an existing storm drain line running under an adjacent city street along a school athletic field and the City of Santa Monica’s Los Amigos Park, routes stormwater and dry-weather flows from the storm drain through a vortex system using a diversion structure into a subsurface water-tight cistern, treats the stormwater and dry-weather runoff with an ultraviolet (UV) treatment system, and delivers highly treated water to the park irrigation system and indoor plumbing system for toilet flushing. The project is unique, perhaps the first of its kind, as a retrofit project, as it takes offsite runoff, treats on site, and uses for two different purposes.
The project’s purpose is to demonstrate the feasibility of harvesting local water resources, including storm drain flows, to decrease potable water use, reduce polluted urban runoff discharge to the receiving water body, and protect the future of California’s water supply. The project implements a UV treatment train system that treats approximately 80 gallons of water per minute (gpm). A jack-and-bore approach was also designed and implemented to reduce construction disturbance within the street. The project contributes to sustainability in the areas of stormwater use, water conservation, water reclamation, and true source control.
