Govt Initiatives in US
San Diego has opted to transform recycled wastewater into drinking water. The City Council voted unanimously to advance a $2.5-billion plan to recycle wastewater, the latest example of how California cities are looking for new supplies amid a severe drought.
The plan is to begin with recycling 15 million gallons by 2023 and progress to 83 million gallons a day by 2035. That accounts for almost one-third of the city’s water supply.
The Orange County Water District is known to serve 2.4 million people in California.It is now planning to boost its recycled water from 70 million gallons to 100 million gallons a day. Previously, it had taken a major step by reusing wastewater for drinking since 2008.
The Santa Clara Valley Water District, which serves 1.8 million people in the San Francisco Bay area, decided to pursue construction of facilities that it says could lead to turning wastewater into drinking water for Sunnyvale and western Santa Clara County.
California recycled about 650,000 acre-feet of water per year (ac-ft/yr) in 2010. That’s not the end of their ambition though. They are now planning to increase water recycling, with a minimum of 1 million ac-ft/yr recycled by 2020, and 2 million ac-ft/yr by 2030.
