Santa Monica announces water system upgrades via design-build

Arcadis has announced it will partner with Kiewit Infrastructure West and PERC Water to serve as the progressive design-build team for the Sustainable Water Infrastructure Project (SWIP) in the City of Santa Monica, Calif.

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 (including the Clean Beaches Initiatives Project, the Enhanced Watershed Management Program and the City of Santa Monica Sustainable Water Master Plan).

Specifically, this innovative project will allow the city to:

  • Reduce energy use and greenhouse gas emissions associated with importing drinking water;
  • Harvest up to 4.5 million gallons of water from any storm for treatment and reuse;
  • Improve beach water quality at Santa Monica Bay by reducing stormwater discharges;
  • Comply with stormwater pollution discharge regulations of 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.

As a sub-consultant to Kiewit, Arcadis will lead the design portion of the project, alongside PERC Water.

“We’re excited to help take City of Santa Monica that much closer to their goal to be water self-sufficient by 2020,” said Christine Cotton, senior vice president of Arcadis North America. “We look forward to partnering once again with Kiewit to bring another new water source to Southern California.”

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), as will new solar panels for energy offset
  • 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 capacity of 4.5 million gallons

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