The city of Santa Monica, California has moved one giant step closer toward water self-sufficiency, according to a story published on the Water Online website. Arcadis, a global design and consultancy firm for natural and built assets, announced recently it will partner with Kiewit Infrastructure West and PERC Water to serve as the progressive design/build team for the city’s Sustainable Water Infrastructure Project.
At present, Santa Monica partially relies on imported water to meet its needs. SWIP will allow the city to move toward true water independence. It supports existing sustainable-water programs, including the Clean Beaches Initiatives Project, the Enhanced Watershed Management Program and the City of Santa Monica Sustainable Water Master Plan.
The SWIP project will allow the city to do a number of things, among them, 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 Santa Monica Bay’s beach water quality by reducing stormwater discharges and comply with the California State Water Board’s stormwater pollution discharge regulations.
In addition, it will allow the city to recycle up to one million gallons per day of municipal wastewater for reuse, including future indirect potable reuse via aquifer recharge, and treat up to 0.5 million gallons per day of stormwater and/or brackish or saline-impaired groundwater for reuse. These measures are expected to allow Santa Monica to conserve over 1,680 acre-feet, or 550 million gallons of groundwater or imported water per year.
“We’re excited to help take the city of Santa Monica that much closer to their goal to be water self-sufficient by 2020,” says 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 design phase is underway, and the project is expected to reach completion in 2020.
