Title

ENV19-0002 (Membrane Filtration Reverse Osmosis Facility - MFRO)

Description

The City currently produces tertiary-treated recycled water (recycled water), which is used for landscape and industrial purposes. Recycled water provided by the City is produced at the Hale Avenue Resources Recovery Facility (HARRF), a recycled water treatment and disposal facility that is owned and operated by the City. The HAR RF provides recycled water to other agencies as well as the City and excess recycled water that is not used by the City or sold to other recycled water customers, is disposed of via an ocean outfall. The City has in the past several years expanded the recycled water conveyance system towards the eastern areas of the City (recycled water pipelines, brine disposal pipeline and fiber optic conduits, recycled wate'r pump station and recycled water storage tank). The City expanded its recycled water system to result in a more dependable and sustainable water supply and to be less dependent on imported water for the City. The Escondido MFRO Facility would provide advanced treatment for Title 22 quality reuse water produced at the HARRF. The facility would utilize membrane filtration (MF) (i.e., microfiltration or ultrafiltration membranes) and reverse osmosis (RO) technologies sized for a total production capacity of 2.0 million gallons per day (mgd). High quality treated water would be blended with Title 22 recycled water within an on-site blend tank. The water would then be sent through the existing non-potable reuse water/agriculture pipelines and distributed to growers. This project component was originally conceptualized as part of the City's Potable Water Reuse Program (Reuse Program) identified in the Recycled Water Master Plan. See NOC for full project description.
