Construction HIGHLIGHTS The Los Amigos Park Stormwater Harvesting & Direct Use
Demonstration Project is a grant funded project to demonstrate the
effectiveness of harvesting urban runoff for beneficial uses such as
indoor flushing and park irrigation, which currently use potable
(drinking) water.
The project is expected to treat up to 550,000 gallons of stormwater and dry-
weather runoff annually. The demonstration project will provide results on design,
installation, and operation which will be relevant and transferable to other projects
and help break down barriers to local water resource development.
The northwest portion of the park, adjacent to Hollister Avenue, will house the
majority of the project. Stormwater and dry-weather discharges from a Los
Angeles County storm drain along 5th Street, that receives runoff from a 50-acre
urbanized watershed, will be diverted into a pre-treatment system before entering
an underground cistern for storage. After passing through an ultraviolet (UV)
disinfection system, treated water will be delivered to the adjacent park restrooms
for indoor flushing, as well as the park irrigation system.
