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 for Aquarion's metered residential bill; Stamford's separate WPCA sewer-user charge uses its own billing cycle and winter-period calculation rules.
- Rate structure
- PURA-approved fixed minimum service charge by meter size plus increasing block consumption rates. The Connecticut schedule effective April 1, 2026 lists a 5/8-inch minimum service charge of $12.89 and residential single-family water rates of $4.343 per CCF for the first 9 CCF, $5.212 for the next 11 CCF, and $6.254 above 20 CCF in the standard division; Stamford's applicable division tariff must be confirmed. The bill also includes 2026 WICA and other regulatory adjustments where applicable.
- Residential cost reference
- For a standard-division 5/8-inch single-family account using about 6,000 gallons per month, the posted April 1, 2026 water schedule implies roughly $40.77 before Stamford WPCA sewer charges and any territory-specific adjustments: $12.89 minimum plus about 8.02 CCF at the first-block rate. Stamford's actual total is higher when its separate sewer-user charge is included.
- Wastewater and sewer calculation
- Aquarion supplies water; Stamford's WPCA separately bills sewer user charges. Stamford states that residential sewer bills are based on winter-period water usage for the dwelling, with a billing/read period distinction, and that water-use questions go to Aquarion while sewer billing appeals go to the WPCA. Repairing leaks and reducing metered winter consumption can therefore affect future sewer charges, but the sewer authority's detailed adjustment rules control.
- Meter reading
- Aquarion bills from metered usage and the account portal provides usage history. The reviewed company pages do not state a universal Stamford read date or hourly AMI schedule; meter technology and replacement work are described through Aquarion's meter program. Customers should use the bill's usage history and high-use indicators to identify leaks.
- New-account deposit
- Residential customers are protected under Connecticut rules from denial solely for inability to pay a security deposit. Commercial tenants must pay a deposit equal to 1.5 months' usage, beginning with $100 and subject to adjustment up to an additional $300 based on actual usage. An excellent credit rating may waive a new-location deposit; after one year with no late notices or fees, the deposit plus interest is credited or returned at final termination.
