City of Denison Utilities Customer Service Division

Provider briefing

How this utility’s billing works

City of Denison Utilities Customer Service Division operates as a municipal department serving Denison and the City of Denison water, wastewater, and refuse service area in Grayson County, including inside- and outside-city customers. 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 Increasing block tiers with a meter-size base charge and inside/outside-city schedules. Effective December 1, 2025, an inside-city residential account with a 1-inch-or-smaller meter has a $36.73 base covering the first 1,000 gallons, then $4.3387 per 1,000 gallons for 1,001–5,000, $5.4234 for 5,001–10,000, and $6.7793 above 10,000. Outside-city residential rates are higher.. Bills are generated monthly billing for water, wastewater, and refuse. denison publishes billing-cycle dates and states that the bill is due 25 days after the bill date., and a typical residential cost reference is For a 1-inch-or-smaller inside-city residential account using 6,000 gallons, the current water component is about $59.51: $36.73 base plus 4,000 gallons at $4.3387 and 1,000 gallons at $5.4234. Using a 6,000-gallon sewer average, sewer is about $64.49: $42.20 base plus 5,000 gallons at $4.4581. Water plus sewer is therefore approximately $124.00 before refuse, taxes, card fees, or other charges; the City’s published minimum combined utility total is lower because it assumes only the base consumption.. 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

Each April, residential sewer is re-averaged from January, February, and March water consumption, and the resulting average controls the sewer rate for the year. The first 1,000 gallons are included in the meter-size base; inside-city residential sewer for a 1-inch-or-smaller meter is $42.20 plus $4.4581 per 1,000 gallons over the base. If a leak adjustment occurred during January–March, the City can re-average before updating the annual sewer average. New accounts remain on the base rate until the next averaging year.

Meter and infrastructure notes

The City’s utility division performs meter reading, meter-leak repair, testing, billing audits, new installs, and disconnects, and the FY2026 budget identifies a dedicated Meter Services division. The current public pages do not state whether residential meters use AMI, AMR, drive-by radio, or manual reads, nor do they publish a read interval. Treat the exact technology and schedule as not publicly stated; the utility bill and Customer Service Division control the account’s actual read and estimated-read notices.
