가뭄에 강하고(drought-proof) 지역적으로 통제할 수 있는 새로운 잠재적인 수자원을 샌디에고와 주변 도시에 제공하기 위한 노력으로 Padre 댐 자치 용수구역의 이사회가 Helix 용수구역과의 중개기관 합의를 승인했다.

이 연구는 Padre 댐의 Ray Stoyer 물 재활용 시설의 확장과 향상된 물 정화 프로젝트 제안의 가능성에 초점을 맞췄다. 이들 계획은 다른 기관의 서비스 지역으로부터 나온 오수를 수용하고 처리하기 위한 목적을 가진다.

 

 

 

SANTEE, CA, Sept. 29, 2014 -- In an effort to provide a potential new drought-proof, locally-controlled source of water to the city of San Diego and surrounding areas, the Padre Dam Municipal Water District's board of directors has approved an interagency agreement with the Helix Water District, City of El Cajon and County of San Diego to study the feasibility of developing its expanded East County Advanced Water Purification Program.

 

The study will focus on the possibility of expanding Padre Dam's Ray Stoyer Water Recycling Facility and proposed Advanced Water Purification Project to accommodate and treat wastewater from the other agencies' service areas in order to provide a recycled water supply for local and regional groundwater recharge, reservoir augmentation and other potable reuse opportunities. The study will be conducted by Padre Dam with assistance from Kennedy/Jenks Consultants.

 

Approximately 16 million gallons per day (MDG) of wastewater is currently generated in the study area with only 2 MGD of this flow treated for water reuse. The 14 MGD of wastewater not treated for reuse travels approximately 20 miles to San Diego's wastewater treatment plant, where it is treated and then discharged into the ocean.

 

This study will explore the possibility of expanding Padre Dam's water treatment capacity, including its Advanced Water Purification Project, to treat the wastewater otherwise being discharged into the ocean to generate a new reliable and local water supply of approximately 10 MGD for potable reuse.

 

The estimated cost of the study is $275,000. The four agencies will each pay $50,000 with the remaining $75,000 to be paid with a Water Recycling Facilities Planning Grant from the California State Water Resources Control Board.

 

Padre Dam's Advanced Water Purification Demonstration Project will begin construction this fall. The demonstration project will take recycled water through four advanced water treatment steps and will be tested daily to ensure it meets the Division of Drinking Water, State Water Resources Control Board's stringent public health objectives.
