Grand Prairie Water Rates and Service Fees

Grand Prairie utility bills can include water usage, a fixed water base fee, wastewater, garbage and recycling, stormwater and applicable service charges. Your actual bill depends on consumption, meter size and account type.

Published Residential Water Charges

The city also publishes a $19.91 monthly water base fee for a residential 5/8-inch meter and a $18.10 wastewater base fee for that meter size. Wastewater consumption is listed at $5.89 per 1,000 gallons, with winter averaging rules affecting eligible accounts.

Common Additional Charges

Amounts are from the city’s published rate schedule, accessed October 2026. A proposed rate change was discussed in January 2026; always compare these figures with your current statement and the official Water Billing Rates page before relying on them for budgeting.

Fixing Common Water Bill and Service Problems

Payment Is Not Showing in Your Account

First review Payment History in the online portal. Match the payment date, amount and confirmation number. If the transaction is missing or the account still shows past due, call 972-237-8200. Avoid paying twice until the first transaction has been checked.

Unexpectedly High Water Usage

Grand Prairie offers H2Know Digital Water Meter, which helps customers check daily water usage and receive unusual-use or possible leak alerts.

1. Visit the city’s H2Know information page.
2. Register or access your water usage account.
3. Compare normal daily consumption with the unusually high period.
4. Check toilets, outdoor faucets, irrigation equipment and underground leaks.
5. Repair confirmed leaks and retain repair documents.
6. Review the official leak-adjustment request instructions if eligible.

The city requires a leak to be repaired before a leak adjustment can be considered. It also instructs applicants to register for H2Know and activate leak alerts.

Water Leak or Sewer Blockage

For water leaks or sewer issues during business hours, use the city’s water-service issue reporting page. For an urgent after-hours leak or sewer blockage, call 972-237-8400.

Give the exact address, nearest cross street, when the problem began and whether it affects your home, yard, street or nearby properties. Avoid contact with sewage and do not operate city-owned valves or meters.

Unable to Pay Before the Due Date?

Contact Water Billing before disconnection. Explain your account balance and ask whether an arrangement or assistance is available. The city has a Water Bill Assistance Program associated with Grand Prairie United Charities.

For assistance inquiries, Grand Prairie United Charities lists 972-262-2014 and 1417 Densman Street, Grand Prairie, TX 75051. Funding and eligibility must be confirmed directly.
