世界上最大的再生污水间接回用饮用水工程近期完成扩建！

A final expansion to the world’s largest indirect potable water reuse facility, the Groundwater Replenishment System (GWRS) is complete, producing 130 million gallons of water a day – enough water to serve nearly one million people in Orange County.

世界上最大的间接饮用水再利用设施——地下水补给系统(GWRS)的最后一次扩建已经完成，每天生产1.3亿加仑的水——足以为奥兰治县近100万人提供用水。

The GWRS now recycles 100 percent of local reclaimable wastewater flows. This expansion maximizes water recycling efforts and increases drinking water supplies for the region.

GWRS现在100%回收当地可回收的废水。这一扩建最大限度地发挥了水循环利用的作用，并增加了该地区的饮用水供应。
这一历史性的里程碑是由项目合作伙伴Orange County Water District (OCWD)和Orange County Sanitation District (OC San)共同完成的  

This historic milestone was achieved by project partners Orange County Water District (OCWD) and Orange County Sanitation District (OC San).

“We are proud to make history once again with the completion of the Groundwater Replenishment System,” said OCWD Board President Cathy Green. “The GWRS is a premier example of vision, innovation, and collaboration – all which are key components of the project’s successes over the years, further cementing our pioneering role in water reuse.” 

The GWRS takes highly treated wastewater that would otherwise be discharged to the ocean and purifies it using a three-step advanced treatment process consisting of microfiltration, reverse osmosis, and ultraviolet light with hydrogen peroxide. The result is high-quality water that is pumped to recharge basins in Anaheim where it naturally percolates into the Orange County Groundwater Basin (Basin) and becomes part of the drinking water supply for 2.5 million people in north and central Orange County. GWRS water is also sent to injection wells located along Orange County’s coast to create a seawater intrusion barrier that protects groundwater supplies.

GWRS将原本排入海洋的经过高度处理的废水，通过微过滤、反渗透和过氧化氢紫外线三步高级处理过程进行净化。其结果是高质量的水被泵送到阿纳海姆的盆地，在那里它自然渗透到橙县地下水盆地(盆地)，并成为橙县北部和中部250万人饮用水供应的一部分。GWRS的水也被送到奥兰治县沿海的注入井中，作为海水入侵屏障，保护地下水供应。

“WateReuse congratulates OCWD and OC San for proving that regional partnership can reap great rewards for the community,” said WateReuse Association Executive Director Patricia Sinicropi. Both OCWD and OC San are longtime leading members of the WateReuse Association (WateReuse). Together with local partners including OCWD and OC San, WateReuse advances laws, policies, funding, and public acceptance of water recycling to improve the resilience, health, and prosperity of communities across the United States.

Craig W. Lichty P.E., WateReuse Association President, and vice president with Black & Veatch, attended a celebration for the completed project. “The Groundwater Replenishment System is a remarkable project. It will benefit the people and environment of Orange County for generations,” he said.

The GWRS first made history when it came online in 2008, bringing water reliability to Orange County. It started producing 70 million gallons of water per day (MGD) in January 2008, increased production to 100 MGD after an initial expansion was completed in May 2015, and since inception has produced more than 400 billion gallons of water and counting. In 2023, the GWRS celebrated its 15 th  “crystal” anniversary.

GWRS于2008年投入使用，首次创造了历史，为奥兰治县带来了可靠的供水。2008年1月，该项目开始每天生产7000万加仑的水，2015年5月完成初步扩建后，产量增加到每天100万加仑。自成立以来，该项目已经生产了超过4000亿加仑的水。2023年，GWRS迎来了15周年“水晶”纪念。  

GWRS water is pumped to recharge basins in Anaheim where it naturally percolates into the Orange County Groundwater Basin, managed by OCWD, and becomes part of the drinking water supply for 2.5 million people in north and central Orange County. GWRS water is also sent to injection wells located along Orange County’s coast to create a seawater intrusion barrier that protects groundwater supplies. It creates a new, drought-proof water supply, decreases the region’s dependence on imported water, and reduces the amount of treated wastewater sent to the ocean.

GWRS的水被抽到阿纳海姆的补给盆地，在那里它自然渗透到奥兰治县地下水盆地，由OCWD管理，成为奥兰治县北部和中部250万人饮用水供应的一部分。GWRS的水也被送到奥兰治县沿海的注入井，以形成海水入侵屏障，保护地下水供应。它创造了一种新的抗旱供水方式，减少了该地区对进口水的依赖，并减少了排入海洋的经处理废水的数量。
