Advanced Water Purification Facility at the City of Los Angeles’ Terminal Island Water Reclamation Plant Earns Envision Platinum Award for Sustainability
The purpose of the $48 million Advanced Water Purification Facility project, funded by California Proposition 84 (the Safe Drinking Water, Water Quality and Supply, Flood Control, River and Coastal Protection Bond Act of 2006) is to provide safe recycled water purified for potable reuse to the surrounding area. Planning for this project started back in the mid 1980’s and the construction of the facility was broken into two phases. Phase 1, completed in 2001, provided 6 million gallons per day (MGD) of recycled water using microfiltration, reverse osmosis, and disinfection with chloramine, and a pipeline distribution network to accommodate up to 22 MGD of recycled water for future phases. Phase 2, completed at the end of 2017, increases the capacity of the facility from 6 MGD to 12 MGD and replaces disinfection with chloramine with a more advanced oxidization process (AOP) that uses a combination of ultraviolet light and sodium hypochlorite. This is the first facility of its kind to use this particular AOP which, in addition to providing high quality potable water, also results in economic benefits compared with more traditional treatment processes.
