Sweetwater는 미국 출라 비스타(Chula Vista)에 위치한 Richard Reynolds 지하수 담수화 시설의 확장을 시작했으며, 사업은 4천200만 달러 규모다. 이번 확장은 1999년 지어진 Richard Reynolds RO 플랜트의 생산량을 하루 식수생산량 40Ml까지, 두 배 가까이 끌어올릴 것으로 기대되고 있다.

급수는 대수층에서 제공받게 되며, 이번 프로젝트는 2017년 늦은 봄께 완공될 예정이다.

 

 

 

Sweetwater Authority has begun its US$ 42 million expansion of the Richard Reynolds Groundwater Desalination facility in Chula Vista.

 

The expansion will double the output of the reverse osmosis plant - built in 1999 - to produce drinking water at 40 Ml/d a day. An aquifer will provide its feed water. The project is scheduled for completion in late spring 2017 when it will serve 30% of the water demand in the Sweetwater District, which includes National City, Chula Vista and Bonita.

 

"The cost of this water is going to be quite a bit cheaper than imported water. It's locally controlled and it's drought proof," said Halla Razak, director of public utilities for the city of San Diego.

 

The expansion is funded in part by grants from the US Bureau of Reclamation and the state of California. The city of San Diego and the Sweetwater Authority will split the remaining cost for The Sweetwater Authority serves western and central Chula Vista, National City and Bonita.
