Just a little info about golf courses and water. Just FYI..........................there's definitely some controversy as to why golf courses are allowed to use as much water as they do.
San Diego Municipal courses (2015 story, might have changed a bit since, and my BOLD)
The Torrey Pines Golf Course uses recycled water. But the city's other two courses, at Balboa Park and Mission Bay, used about 116 million gallons of tap water during the ten months ending April 30, records show.
Phoenix, a bit more recent news. They use a mix of water including a lot of groundwater and CAP water:
State records show there are 165 golf courses in the Phoenix area. They use various sources of water, including treated wastewater and Colorado River water. But more than half of the area's courses rely at least partially on groundwater, together pumping roughly as much from wells as the average consumption of 130,000 single-family homes.
Las Vegas, 2017. Seems they use brown water primarily, but something to think about is that treated effluent is not going back into the Colorado River as it would be if it wasn't used on a golf course
The water itself is “brown” — effluent water straight from the county wastewater treatment plant, not drinking water from Lake Mead. It’s high-quality re-use, but it still contains salts that course superintendents have to deal with.
One golf course in Utah, story from March this year. "Cutting back" to +/- 100 Million gallons used per year (enough for about 1000 households at the ave. of 300 gal/day/household) Multiply that by 120 or so courses in Utah. And Utah ranks as one of the fastest growing States in the West.
That’s why the course is upgrading the irrigation system, which previously used about 145 million gallons per year. Golf course managers, players and ordinary citizens alike are realizing that such numbers aren’t sustainable. Entrada hopes to get down to somewhere in the range of 105 million to 115 million gallons a year using the most innovative methods, and not a moment too soon.
