Green grass on golf courses have been found to help replenish drinking water supplies, according to the South Florida Sun Sentinel. Experts say that the courses use a great deal of water in operating, but help mitigate effects of heavy rains when they occur.
When the severe downpours do occur, the golf courses give back 15 times the water that they use to drinking water aquifers. The long, clear fairways and open green turf provides minimal resistance for rain water as it flows back underground.
The turf grass used on the courses is a coarse plant with a dense root system and also helps filter the water before it goes back into the aquifers. The courses studied, in Florida’s Palm Beach County, collected more than 60 billion gallons of drinking water in just 60 days.
