How this utility’s billing works
Town of Cary Utilities operates as a municipal department serving Cary, Morrisville, and Research Triangle Park service areas. 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 tiered potable-water pricing plus a meter-size monthly base fee, with separate irrigation and reclaimed-water rates. FY 2026 single-household water usage is $5.46 per 1,000 gallons for 1-5,000 gallons, $6.13 for 5,001-8,000, and $7.74 above 8,000, plus the applicable base and local-government charges..

The published sewer rate is $11.69 per 1,000 gallons, so a 5,000-7,000 gallon water-and-sewer subtotal is approximately $89.84-$125.09 before other bill components.. 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
Cary bills sewer by metered water use at $11.69 per 1,000 gallons in the FY 2026 inside-service rate sheet, plus applicable base or local-government charges. Reclaimed-water usage is separately priced and does not receive the same leak-adjustment treatment as potable water; the reviewed pages do not describe a winter-average sewer cap.
Meter and infrastructure notes
The reviewed Cary pages link customers to Aquastar for usage viewing and alerts but do not identify a single AMI vendor, hourly interval, or route calendar. Customers can monitor usage and alerts in Aquastar and should report unusual readings with the repair date and type when requesting an adjustment.
Emergency water support
Report a leak or water emergency
Dial 311 inside Cary or (919) 469-4000 outside town limits for water, sewer, or reclaimed-water service issues. The reviewed Cary pages use 311 for utility requests and do not expose a separate water-only 24/7 hotline; active public leaks should be reported immediately through the Town's emergency request route.

Reading this profile
A practical reference for Cary, Morrisville, and Research Triangle Park service areas
Town of Cary Utilities is listed here as a municipal department. The profile separates account actions—such as paying a bill or requesting service—from explanatory material about rates, meters, wastewater, leaks, and delinquency.
Because utility rules can vary by account class, meter size, service address, billing date, and local ordinance, treat the published bill and current provider website as the final authority. Use this profile to locate the correct channel and prepare better questions for customer service.
If your issue is urgent, start with the provider’s emergency number or official payment route rather than waiting for an email response. Keep a written record of calls, confirmation numbers, notice dates, and documents you submit.
