Arcadis, Kiewit to support sustainable water project in US

Arcadis has announced a partnership with Kiewit Infrastructure West and PERC Water to provide design and engineering services for the Sustainable Water Infrastructure Project (SWIP) in the City of Santa Monica, US.

The SWIP project is expected to take Santa Monica closer to becoming water self-sufficient, ensuring sustainable water supply and reducing the costs of importing water.

It will also support existing programmes created to ensure sustainable water supply, including the Clean Beaches Initiatives Project, the Enhanced Watershed Management Program and the City of Santa Monica Sustainable Water Master Plan.

Arcadis North America senior vice-president Christine Cotton said: “We’re excited to help take City of Santa Monica that much closer to their goal to be water self-sufficient by 2020.

“We look forward to partnering once again with Kiewit to bring another new water source to Southern California.”

With a total budget of $56.88m, the SWIP would deliver energy savings and cut greenhouse gas emissions associated with importing drinking water.

It involves the construction of three new water treatment and storage facilities designed to harvest and treat nonconventional water resources, such as stormwater, brackish/saline impaired groundwater, and municipal wastewater, for reuse.

Up to 1.5 million gallons per day (MGD) of new water would be made available for non-potable reuse.

This includes recycling of up to 1MGD of municipal wastewater for reuse, including for future indirect potable reuse (IPR) via aquifer recharge.

In addition, the initiative will help the city to conserve more than 550 million gallons of groundwater or imported water per year.

Arcadis, which serves as a sub-consultant to Kiewit for the project, will lead the design portion alongside PERC Water.

Infrastructure to be built as part of the project includes reverse osmosis technology for the treatment of brackish/saline-impaired groundwater and stormwater at the Santa Monica Urban Runoff Recycling Facility (SMURRF), sewer lift stations and a below-grade stormwater and sewer treatment facility.

Besides, the project will include stormwater lift stations and a stormwater harvesting tank with an aggregate storage capacity of 4.5 million gallons.

The completion of the SWIP project is anticipated to take place in 2020.
