Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- 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.
- Rate structure
- 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.
- Residential cost reference
- 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.
- 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 reading
- 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 documented; the utility bill and Customer Service Division control the account’s actual read and estimated-read notices.
- New-account deposit
- Current service-request instructions require a completed application, proof of legal tenancy or ownership, photo ID, payment of past-due balances, a $100 security deposit, and a $35 residential or commercial connection fee. The deposit is applied to the final bill when service terminates; if a current customer transfers without a $100 deposit, the difference must be paid. New construction and specialty meters can have separate connection, tap, meter, or hydrant deposits.
- Activation or transfer fee
- The current service-fee schedule lists a $35 residential or commercial connection fee and a $30 transfer-service fee. The transfer process permits the old account to remain active for up to 30 days after the new account connects, requires proof of tenancy/ownership and payment of past-due balances, and requires the deposit to be brought to $100 if the old account lacked that deposit.
