Average Residential Water Usage

During the summer months, the District receives calls from a few of its customers who don’t believe that they could have used the amount of water for which they have been billed.  There are a lot of reasons for increased water usage, particularly during the summer months.  Many of our residents are irrigating their landscapes once the warm weather starts.  School-aged children are home and they may not be as mindful of their water usage habits as those of you who pay the water bill.  On an individual basis, there may be other reasons for increased water usage.  A toilet with a stuck open stopper will consume up to two gallons of water per minute.  If it’s stuck open for ten hours, that’s 1,200 gallons of water flowing through your meter.  A toilet stopper that is stuck open for a week will waste over 20,000 gallons of water.

Then there are the not-so-obvious reasons for an increase in water usage: an irrigation zone valve that doesn’t completely close; a silent and invisible toilet leak; or an outside hose bib that’s not completely turned off.

The graph below shows the monthly trends in average water usage among the District’s residential customers.  The lowest average water usage since the April 2016 billing was in March 2017 when the District’s customers used an average of 3,867 gallons of water.  Highest average water usage during the same period was 12,314 gallons that was billed in July 2017.  This reflects the water usage for month previous to the billing month.

There are several resources under Your Resources on this website that will instruct you on how to check for leaks and read your water meter.
