Ever since the current drought has been confirmed by our Governor, Jerry Brown, the first question I get from everyone is “can I fill my pool?” or “can I build a swimming pool in the drought”.
There are no restrictions on filling and maintaining a pool during a drought.
Here are a couple of little known facts;
Once the swimming pool is full, the only water a swimming pool uses is to refill water from splash-out and evaporation, and this is a minor amount of water. The water recirculates through it’s filtration system and so it is used again and again.
As an example; a lawn that has 4 sprinkler heads @ 2gpm, running for 20 min a day 3 times per week will use 500 gallons per week. In about 9 months your landscaping will use as much water as it takes to fill a swimming pool. And once you fill a swimming pool the pool keeps it’s water for 15+ years.
In other words the best advice is; You can save water by replacing your lawn with a swimming pool.
