The project will allow treated wastewater in the southern part of the Metropolitan Wastewater System to be reused in San Diego, Imperial Beach, Chula Vista, National city, and areas outside of San Diego county. The plant has an initial treatment capacity of 7 million gallons per day (mgd), with the capability to expand. The project will decrease the burden on the already overloaded treatment facility at Point Loma, and lessen the city's use of primary water from its source for certain activities.
