Summer Water Usage A Closer Look

​A Closer Look At Summer Water Usage

The City of Coppell Water Billing Department​ understands that some Coppell water customers may have concerns regarding water bills and the usage reported for the months of August, September and October.  We would like to provide some information to assist customers when analyzing usage.  

The highest water usage over the course of a year occurs during the summer months. Summer 2015 temperatures were normal for the months of June and July.  However, August, September and October temperatures ran higher than average.  Higher than average temperatures, both night and day, coupled with drier than normal conditions pushed the north Texas area back into severe drought status.  Reference: 

During the month of August 2015, the City experienced an increased demand on the municipal water system.  Because water usage was extremely high, the City had to increase its purchase of daily water to meet the demand.  The daily amount of water Coppell was contractually allowed to purchase from DWU stood at 18 million gallons per day (MGD) until August 2015 when that amount was increased to 18.5 MGD.  The City did not see evidence of a significant reduction in water use by Coppell water customers during the month of September.  

Purchasing additional water from DWU was necessary for a variety of reasons.  Most importantly, low levels of water in the elevated tanks can hamper firefighting efforts.  To ensure public safety, the City’s first course of action was to turn off the irrigation systems throughout the parks and city-owned facilities. The next step was to ask Coppell ISD to limit watering to help conserve.  Usage continued to increase at which point the city officials found it necessary to purchase additional daily water from DWU. 
Several water customers have called the City’s Utility Billing Department this summer to discuss the receipt of what they detect is a higher than average water bill.  Higher than normal bills during the summer months may be affected by summer water conservation rates.  

According to the Texas A&M AgriLife Extension website ( ), “from 50- to 75-percent of a home’s total water use during the growing season may be for outdoor purposes.”  Coppell’s tiered summer water rates come into play after the first 25,000 gallons of water have been consumed.  Approximately 4,600+ residential water accounts actually reached the 25,000+ gallon level this summer, kicking in the summer water conservation rate.  The City has a total of 12,914 service connections.

Higher than normal water usage can be attributed to a variety of factors including drought, addition of a pool or automatic irrigation system, or an undetected leak.  Water irrigation systems can use more water than necessary if not set properly.  Please contact your installer or a local nursery for advice.  Irrigation systems should also be checked regularly for leaks, and remember when the power goes out, your automatic irrigation system may reset to a default setting.  Be sure to check your automatic irrigation system regularly to test the timings, check the zones and look for leaks. 

The American Water Works Association (AWWA) has determined that homes with in-ground automatic irrigation systems use 35% more water than those without irrigation systems. And those households using automatic timers for their irrigation systems use 47% more than their neighbors with in-ground systems operating their systems manually.  If you are interested in ideas on how to save water outdoors, please visit:
