If you want to enjoy your home swimming pool and still save water, Cal Poly researchers said it’s possible you just need to cover up.

Pool owners can help the state enough water for about half a million people to use each year.

 

Misgana Muleta, associate professor at Cal Poly’s Civil and Environmental Engineering department said, “The number we had was up to 55,000 acres of water can be saved. Which is good enough to provide a city of half a million in population with water for the entire year.”
