Provider briefing

How this utility’s billing works

Corpus Christi Water (City of Corpus Christi Water Utilities) operates as a municipal department serving Corpus Christi and regional wholesale water customers in the Coastal Bend. 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 conservation tiers effective January 1, 2026. Inside-city residential water uses a $17.25 monthly minimum meter charge for a 5/8 x 3/4-inch meter, then $0.75 per 1,000 gallons for the first 2,000 gallons, $4.06 for the next 4,000, $7.11 for the next 9,000, $11.17 for the next 10,000, and $16.24 for consumption over 25,000 gallons. Outside-city minimums and meter charges differ. The rate schedule also separates commercial, irrigation, large-volume, agency-resale, raw-water, and reclaimed-water services.. Bills are generated monthly, based on a 30-day billing-cycle calculation for residential water rates. utility bills carry the metered consumption used for the current water charge and the winter-quarter average used for residential wastewater., and a typical residential cost reference is Using the January 1, 2026 inside-city schedule, a 5,000-gallon household has approximately $30.93 in water charges ($17.25 minimum plus $1.50 for the first 2,000 gallons and $12.18 for the next 3,000). If its winter-quarter wastewater average is also 5,000 gallons, wastewater is approximately $63.52 ($38.29 minimum plus three 1,000-gallon units at $8.41), for an estimated $94.45 water-and-wastewater subtotal before stormwater, solid waste, and other statement charges. At 7,000 gallons, the comparable subtotal is roughly $119.39 before those other municipal charges.. 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

Residential wastewater is not directly metered. Corpus Christi uses Winter Quarter Averaging: three consecutive winter billing cycles based on December, January, and February usage, reflected on the January, February, and March utility bills. The average is converted to a 30-day monthly quantity and remains fixed for one year. Effective January 1, 2026, inside-city single-family and duplex wastewater is $38.29 per month for up to 2,000 gallons, then $8.41 per 1,000 gallons over 2,000, capped at 25,000 gallons and therefore $231.72 maximum per month. Customers moving during the winter period receive an interim average; the City publishes the 2026–2027 interim average as 4,339 gallons.

Meter and infrastructure notes

The City bills from metered consumption and calculates residential rates on a 30-day billing cycle. In 2026 Corpus Christi launched an online Water Usage Portal where customers can view current billing-cycle data, daily usage averages, and a historical breakdown covering the prior year; the City also provides a residential water-charge calculator and a Winter Quarter Average calculator. The public pages do not identify a single AMI/AMR vendor, radio protocol, or guaranteed hourly transmission interval, so the verified description is monthly billing-meter data supplemented by customer-facing usage analytics.
