Anthem Country Club just replaced all 18 greens and fairways. That effort is expected to save around 30,000,000 gallons of water a year. … The course has been closed since last June to make the changes and just reopened last Friday. The Southern Nevada Water Authority is requiring golf courses to reduce their water budgets by 2024 or face a significant penalty. … A water savings of 30,000,000 gallons of water per year is equivalent to filling up 600,000 50-gallon bathtubs. If Anthem Country Club saved that much water a year for 30 years, the Southern Nevada Water Authority says that would about fill up the entire Luxor pyramid.
