지난 12월 18일 캘리포니아 남부 물 보충구역(WRD)이 새롭게 활장된 Leo J. Vander Lans  고도 수처리 시설(LVLAWTF)에 대한 헌납식을 개최했다. 이 새 개발로 고도 수처리 시설은 앞으로 하루 생산량 300만 갤런 용량에서 800만 갤런으로 용량이 확대될 전망이다.

WRD 이사회 대표 Sergio Calderon는 이 확장에 대해 “캘리포니아 남부 물 보충구역과 하루하루 우리의 지하수 공급에 의존하는 우리 서비스 구역의 4백만 거주민에게 있어 역사적인 순간을 기록했다”고 말했다.

 

 

 

On Thursday, Dec. 18, the Water Replenishment District of Southern California (WRD) held a dedication ceremony for its newly expanded Leo J. Vander Lans Advanced Water Treatment Facility (LVLAWTF). With the new development, the advanced water treatment facility will now go from producing 3 million gallons of treated wastewater per day to 8 million gallons per day.

 

The expansion "marks an historic moment for the Water Replenishment District of Southern California and for the 4 million residents in our service area who rely on our groundwater supply for daily life," said WRD Board President Sergio Calderon. "With the expanded Leo J. Vander Lans Treatment facility online, the recycled water we now produce brings us ever closer to our goal of 100-percent independence from expensive and unreliable imported water."

 

In addition to the increase of 5 million gallons of recycled water that will be produced each day, the plant has now further reduced waste and raised overall recovery from 77 to 92 percent, propelling VLVLAWTF forward into water efficiency.

 

"This state-of-the-art facility is a leader in advanced water treatment," stated WRD Board Treasurer Albert Robles. "WRD is not just breaking new ground, but leading the water industry into a sustainable future that will shield us from future droughts like the one we are currently facing."

 

The Alamitos Barrier that currently protects the groundwater in the Central Basin from coastal saltwater intrusion will now use 100-percent recycled water produced from LVLAWTF. As water pumpers extract water from the Central Basin, natural water pressures that keep saltwater from entering into and contaminating the groundwater basin are reduced.

 

Consequently, millions of gallons of freshwater needs to be injected into the ground to serve as a barrier and prevent saltwater contamination. The expansion project means that WRD will not need to utilize any imported water in the Alamitos Barrier, thus reducing reliance on water imported from northern California.
