What is the city's response to high water bills?
Grand Prairie Water takes your concerns seriously and has investigated possible causes of higher-than-expected bills. We look at water usage patterns and historical trends; and study for possible leaks, billing errors and meter issues.
As promised, the City of Grand Prairie has conducted an independent audit of its water metering and billing operations. View water audit results.
So why are bills so high?
Higher water bills can occur for one or more of three reasons:
- customer consumed more water
- misread meter
The most common causes of high water use are irrigation systems and/or leaks.
High Water Consumption and Tiered Billing Structure
Grand Prairie, along with cities across the country, uses a tiered water rate structure for all residential water customers. This structure is part of the city’s Water Conservation Plan, mandated by the State, designed to encourage water conservation. Customers who use less water not only buy fewer gallons, but also enjoy lower rates on what they do buy. The more water a customer uses, the more gallons they must buy and if that total exceeds 20,000 gallons in a month, the water rate goes up too. High levels of water usage can get expensive quickly.
The City of Grand Prairie is a water customer of the Dallas Water Utilities and Fort Worth Water, which provide the city with treated water. As the city purchases water in higher volumes for its customers, rates charged to the city rise proportionally for raw water purchases, water treatment, chemicals, debt service to fund federal environmental mandates, and infrastructure—in addition to any additional rate increases levied by Dallas or Fort Worth. As with other cities, these costs are passed through to the retail customer.
