[미국] Padre 댐 향상된 물 정화 프로젝트 위해 1백5십만 달러 수여

2014년 9월 5일 미 캘리포니아주 샨티에서 산티에고 동부에 물을 공급하고 있는 Padre 댐의 지자체 물 구역 이사회는 새 향상된 물 정화(AWP) 시설 건설 프로젝트에 착수해 통합적인 물 서비스를 제공하기 위해 1백5십만 달러짜리 계약을 승인했다고 밝혔다. 이 프로젝트는 안전하고 믿을 수 있으며, 통제 가능하고 환경적인 지역에 잠재적인 새로운 물 자원을 공급할 것이다.

3백만 달러의 정부 보조금을 받은 이 계약은 새 AWP 기술을 적용한 시범 공장의 건설과 설치를 포함한다. 이 프로젝트는 네 단계의 향상된 물 관리 과정을 거쳐 재활용된 Padre 댐의 물을 사용할 것이다. 단계는 염소 살균소독, 멤브레인 정화, 역삼투, 자외선 산화(UV advanced oxidation) 과정이다.

Padre Dam awards $1.5M contract for advanced water purification project
    
the board of directors for Padre Dam Municipal Water District, serving East San Diego County, Calif., approved a $1.5-million contract for Integrated Water Services to construct a new Advanced Water Purification (AWP) Demonstration Project that will provide a potential new source of water to the region that is safe, reliable, locally-controlled, drought-proof, and environmentally sound.

The contract, funded through a $3-million state grant, includes the construction and installation of a pilot demonstration plant that will use AWP technologies. The project will take Padre Dam's recycled water through four advanced water treatment steps -- free chlorine disinfection, membrane filtration, reverse osmosis (RO) and ultraviolet (UV)/advanced oxidation. The water produced will be tested daily to ensure it meets the public health objectives for the California Public Health Department and will not be used in the drinking water system.

The Demonstration Project will produce water for one year and will not impact water rates. Construction work will begin in the fall of 2014 and is scheduled to be completed by February 2015. At completion of construction, the demonstration treatment facility operations will begin and run at least 12 months. During this time, the Demonstration Project will produce approximately 100,000 gallons per day (GPD) of advanced treated water for demonstration and testing purposes.

If the Padre Dam's Demonstration Project is deemed successful and the AWP project moves forward, the water treatment process would continue with additional steps and be similar to the successful Groundwater Replenishment System in Orange County (see "Orange County's GWRS Exemplifies Power of Collaboration"). After treatment, the water would be injected into the Santee groundwater basin where it would be naturally filtered and then withdrawn and treated again prior to distribution as drinking water. The project would have the potential to distribute up to 3 million gallons per day (MGD) of water or enough to serve approximately 5,500 households and businesses in the Padre Dam's service area each year.
