캘리포니아의 Woodland-Davis Clean Water Agency(WDCWA)는 악화된 지하수 제공자를 더 안전하고 믿을 수 있는 지표수 공급자로 대체된 새로운 지역 지표수 처리 플랜트의 건설을 관찰하기 위해 획기적인 행사를 개최했다.   

WDCWA는 세계적인 컨설팅과 설계, 건설, 운영 회사인 CH2M HILL 채택했다. CH2M HILL는 2013년 10월 시설의 장기간 운영과 건설 설계를 위한 1억4천100만 달러를 계약했다. 강으로부터 매년 4만5천 acre-feet를 우회시키고 완전하게 하기 위한design-build-operate(DBO)프로젝트의 건설과 운영비용은 적합하게 책정됐다. 또한, 프로젝트는 두 도시와 잠재적인 UC Davis의 고객에게 매일 3천 갤런의 물을 공급한다.

California's Woodland-Davis Clean Water Agency (WDCWA) hosted a groundbreaking event to observe the start of construction on the new regional surface water treatment plant, which will replace deteriorating groundwater supplies with safe, more reliable surface water supplies from the Sacramento River.

WDCWA awarded CH2M HILL, a global full-service consulting, design, construction, and operations firm, a $141-million contract for the design, construction and long-term operation of the facility in October 2013. The design-build-operate (DBO) project will optimize construction and operation costs for the cities of Woodland and Davis and when complete, divert approximately 45,000 acre-feet of water per year from the river. In addition, the project will supply 30 million gallons of water per day to water customers in the two cities and potentially UC Davis, with future expansion capabilities to 34 mgd.

The surface water treatment system includes construction of a jointly-owned and operated water intake on the Sacramento River, raw water pipelines connecting the intake to a new regional water treatment plant, and separate pipelines delivering treated water to Woodland and Davis. Additional improvements to the cities' existing water supply systems, including distribution pipelines, water storage tanks, and pump stations, are also included in the project scope. The new regional surface water treatment plant is expected to open in the fall of 2016.
