Sustainable Water Infrastructure Project

Santa Monica, CA

Partnering with Kiewit Infrastructure West and Arcadis, PERC Water is part of the progressive design-build team for the Sustainable Water Infrastructure Project (SWIP) in the City of Santa Monica, California. Currently, the City of Santa Monica partially relies on imported water to meet its water needs. This project will allow the City to take a major step toward water independence, supporting existing programs designed to create a sustainable water supply.

Specifically, this innovative project will allow the City to:

  • Reduce energy use and greenhouse gas emissions associated with importing drinking water
  • Improve beach water quality at Santa Monica Bay by reducing pollution related to stormwater
  • Comply with stormwater pollution reduction regulations of the State Water Board
  • Recycle up to one million gallons per day of municipal wastewater for reuse, including for future indirect potable reuse (IPR) via aquifer recharge
  • Treat up to a 0.5 million gallons per day of stormwater and/or brackish/saline-impaired groundwater for reuse
  • Conserve more than 1,680 acre-ft (about 550 million gallons) of groundwater or imported water per year

The SWIP will provide the following:

  • Reverse osmosis technology to treat brackish/saline-impaired groundwater and stormwater at the Santa Monica Urban Runoff Recycling Facility (SMURRF)
  • New solar panels for energy offsets
  • Sewer lift stations and a below-grade stormwater and sewer treatment facility at the Civic Center parking lot, with the ability to treat 1 million gallons of wastewater or harvested stormwater per day
  • Stormwater lift stations and a below-grade stormwater harvesting tank at the Civic Center parking lot, with a total storage capability of 4.5 million gallons

The design phase is underway and the project is expected to be complete in 2020.

Project Highlights

  • Harvest up to 4.5 million gallons
  • Treats up to 1.5 MGD
  • Conserves 550 million gallons per year
  • Reverse osmosis
  • Solar panels for energy offset
  • Lift stations below-grade
  • Below-grade treatment facility
  • Surface improvements for community and mobility benefits
