Provider briefing

How this utility’s billing works

City of Grand Prairie Water Utilities Department operates as a municipal department serving City of Grand Prairie municipal water, wastewater, garbage/recycling, and stormwater service area. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.

The published water-rate framework is described as Tiered conservation billing. Residential 5/8-inch base fee $19.91; 3,000 gallons or less is $0.15 per 1,000 gallons; 3,000–10,000 is $5.06/k; 10,001–20,000 $6.74/k; 20,001–30,000 $10.25/k; over 30,000 $12.82/k. Additional unit fee $3.02. Residential stormwater is a property-area fee.. Bills are generated monthly; current portal transition material states the monthly format continues and the statement due date remains 21 days after the statement date., and a typical residential cost reference is Assuming a 5/8-inch meter, a winter sewer average equal to actual use, a property over 2,500 sq ft, and the 8.25% garbage tax, 5,000 gallons is approximately $45.21 water ($19.91 + 5k×$5.06), $47.55 wastewater ($18.10 + 5k×$5.89), $24.10 garbage/recycling including tax, and $5.43 stormwater, about $122.29/month. At 7,000 gallons, the corresponding estimate is $55.33 water + $59.33 wastewater + $24.10 garbage + $5.43 stormwater, about $144.19. Actual wastewater follows the November–February WMA and the highest winter month is dropped; new accounts use 80% of current water, max 12k, until established.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.

Wastewater and sewer calculation

Standard residential wastewater is $5.89/k plus a $18.10 5/8-inch base. Grand Prairie computes the winter-month average from November, December, January, and February, drops the highest month, and uses the average of the three lowest months for the following 12-month period, updated every April. New residential accounts are billed at 80% of current water use, max 12,000 gallons, until they have qualifying history.

Meter and infrastructure notes

Grand Prairie offers H2Know Digital Water Meter access so customers can view actual use online 24/7 and activate leak alerts. The new SpryPoint portal also displays water usage and bill history. Current public pages do not disclose the hardware vendor, AMI/AMR rollout status, or a universal transmission interval; the record therefore identifies the customer-facing digital usage platform rather than asserting a physical read schedule.
