Payment channels

Pay Aquarion Water Company of Connecticut - Stamford Division

Use the provider’s verified online, telephone, mail, or counter instructions. Check the final confirmation screen for the amount, processing date, and any transaction fee before submitting.

Primary online route

Use the official payment portal

The direct portal is the fastest route when it is available. The provider identifies its payment gateway as KUBRA payment processing through Aquarion's secure customer portal. Never enter account credentials into a lookalike site reached through an unsolicited message.

Telephone payment

Phone IVR

866-446-2516 for 24/7 automated one-time payment; Aquarion customer service and emergencies are 1-800-732-9678.

Have your account number and payment instrument ready. Follow the provider’s recorded prompts and retain the confirmation number.

Alternative channels

Mail, text, and in-person payment instructions

Pay by text

Aquarion documents portal reminder notifications and mobile-app account management, but the reviewed Connecticut pages do not publish a text-to-pay keyword or dedicated SMS payment enrollment sequence. Customers can enroll in the portal using the account number and mailing ZIP code and configure available reminder notifications; carrier charges may apply.

Mail-in address

Aquarion Water Company of CT, P.O. Box 3664, Portland, ME 04104-3664 for the Stamford-format bill. Include the account number and payment stub; do not send cash. The bill also shows correspondence remittance through Aquarion Water Company of CT, P.O. Box 9265, Chelsea, MA 02150-9265, so customers should follow the address printed on their current bill.

Counters, drop boxes, and office hours

Aquarion's reviewed billing page emphasizes online, phone, bank-account, and Auto Pay options and does not publish a stable Stamford counter location or current payment-center hours. Stamford sewer-user charges are administered separately by the Stamford WPCA, whose customer service office at Stamford Government Center, 10th floor, accepts in-person sewer payments Monday-Friday 8:30 a.m.-3:30 p.m.; customers should not confuse that sewer office with Aquarion water billing.

Accepted digital instruments

What you can use online

Aquarion's portal and one-time payment path accept checking-account payments and credit cards; Auto Pay and paperless billing are available. The Stamford service can use the Aquarion mobile app. Apple Pay, Google Pay, debit-card brand acceptance, and text-to-pay were not specifically identified for this division.

2026 transaction pricing

Convenience fees

For Connecticut residential customers, Aquarion's current billing page does not list a one-time KUBRA fee; the $1.95 KUBRA service fee is expressly identified for Massachusetts and nonresidential Connecticut/New Hampshire customers. A credit-card single transaction is limited to $1,000. Customers should confirm any current residential card fee at checkout.

Fees can vary by payment type, channel, account class, and processor terms. The checkout screen is the final fee disclosure.

Payment guidance

Choose the payment channel that fits your deadline

The safest payment path is the one published by Aquarion Water Company of Connecticut - Stamford Division and matched to the account information on your bill. Online portals are convenient, but telephone, mail, counter, and drop-box options may follow different posting schedules and may use different fees.

For a routine payment, save the final confirmation page or IVR number and check when the transaction will post. For a same-day shut-off notice, do not assume that submitting a card payment automatically stops a field order; ask the provider what amount and confirmation are required.

Never send your account number, password, card details, or bank information to Water Ledger. Those details belong only on the provider’s verified payment channel or at an authorized counter.
