Squeezing Every Last Drop

Constructed in 1995, West Basin’s Edward C. Little Water Recycling Facility (ECLWRF) treats municipal secondary effluent from the City of Los Angeles’ Hyperion Wastewater Treatment Plant for a variety of reuse applications. West Basin has expanded the ECLWRF four times since startup, and has also added three satellites treatment facilities, which all work together to produces five (5) distinct water qualities from the source water. Since 1997, three of these five water qualities have relied on membrane treatment to achieve the product goals, including microfiltration for fine particulate removal and reverse osmosis for salt reduction. The most recent expansion of ECLWRF also included ozone addition as pretreatment to the MF system. This presentation will provided attendees with an overview of West Basin MWD’s recycled water program, illustrating how a utility can supplement their water supply with recycled water, and the role that membranes can play in such an effort.
