Welcome to the Edward C. Little Water Recycling Facility in El Segundo, California, the only facility in the world that makes 5 different types of recycled water. Take a self-guided tour of our water-efficient demonstration garden.
Reverse Osmosis technology is widely used to remove impurities from water to make it safer to drink. It's also used to make recycled water cleaner for use in industrial processes and for injection into our groundwater basins to later become part of our local drinking water supply.
Ultraviolet light is the final step in the purification process and creates 'ultra-pure' water that is similar to distilled water. It is combined with hydrogen peroxide to provide multiple barriers against some organic compounds and possible unknown contaminants.
West Basin takes water quality seriously, conducting more than 25,000 water quality tests each year in the water quality lab at the Edward C. Little Water Recycling Facility.
The control room operates 24 hours a day, 7 days a week to monitor the water purification processes throughout the facility. West Basin’s contract operator, United Water, staffs 47 personnel to facilitate water quality, operations and maintenance at this facility.
Microfiltration removes bacteria, protozoa and suspended solids as water is pulled through holes (1/300th size of human hair) in the sides of "straw-like" microfiltration membranes.
Title 22 water, or tertiary water, is the most common type of recycled water, used predominately for landscaping on golf courses, ballfields, parks, and street medians.
West Basin's recycled water production reduces the amount of treated sewage dumped into Santa Monica Bay by 5 tons a day. This room of floor-to-ceiling plates removes remaining water from solid waste to be used in local landfills as organic cover.
10% of West Basin's peak energy demand at the Edward C. Little Water Recycling Facility is produced with solar power. Almost an acre of land at the facility hosts solar panels.
