"Waste-water recycling is one of them"

It is.... 2 examples of Big Government in action below. Drip irrigation is another way. IIRC, only 50% of the farms irrigate with drip.

California's Orange County Water District (OCWD), through a pioneering wastewater treatment facility that recycles used water -- or sewage -- and returns it to the drinking supply. The plant is expanding production from 70 to 100 million gallons per day, enough for 850,000 people, around one-third of the county population. As the OWCD output is mixed with the main groundwater supply it reaches over 70% of residents.

Water Recycling Comes Of Age In Silicon Valley

Audio Report by Amy Standen for QUEST Northern California on Jul 19, 2013


This fall, Santa Clara county residents will get a new source of water. This water is local and pristine. In fact, it's cleaner than almost anything coming out of taps today. But – for now at least – no one will drink it.

Instead, water from the $68 million Silicon Valley Advanced Water Purification Center will flow into segregated, purple pipes to irrigate lawns and cool power plants.

That's because the water is recycled from wastewater – sewage – from a wastewater treatment plant across the street. Engineers say it's possible to purify sewage water until it's cleaner than much of what residents drink today. The bigger challenge, they say, is convincing people to drink it.
