Sustainable Water Infrastructure Project (SWIP)
Project Background
The City of Santa Monica Sustainable Water Infrastructure Project (SWIP) is a first of its kind project that provides a drought resilient water supply for the City. The SWIP Consists of three integral project elements:
- Element 1: Stormwater, Dry Weather Urban Runoff Treatment and Reuse
- Element 2: Stormwater and Municipal Wastewater Treatment and Potable Reuse
- Element 3: Stormwater Harvesting
Together these elements will work together to produce up to 1,680 acre-feet per year of advanced treated recycled water or roughly 10% of the City's water supply to reduce the City's reliance on imported water supplies. Other key benefits of the SWIP include:
- Diversifies the City's water supply portfolio with a drought resilient source
- Improve water quality in the Santa Monica Bay through the reduction of stormwater discharges
- Comply with State Municipal Separate Storm Sewer System (MS4) and Enhanced Watershed Management Plan (EWMP) stormwater nonpoint source pollution control measures for Santa Monica Bay
- Recycle 1.0 million gallons per day (MGD) of municipal wastewater for permitted reuse, including future indirect potable reuse via aquifer recharge
- Treat up to 0.5 (MGD) of stormwater, dry weather urban runoff, and/or brackish-saline-impaired groundwater for permitted beneficial reuse
- Replenish the City's local groundwater supply with a sustainable, drought resilient source
- Contribute to achieving self-sufficiency goals identified in the 2018 Sustainable Water Master Plan

PUBLIC HEARING NOTICE
The City is seeking to amend the Sustainable Water Infrastructure Project’s (SWIP) non-potable reuse permit, Order No. R4-2021-004, with the California Regional Water Quality Control Board - Los Angeles Region and expand its use for indirect potable reuse – groundwater replenishment via subsurface application. The purpose of the meeting is to provide an opportunity for the public to comment on the use of advanced treated recycled water from SWIP to augment the City’s groundwater supply at the Olympic Well Field.
