Payment channels

Pay Aquarion Water Authority

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 MuniOS is linked by the new Aquarion Water Authority; legacy Aquarion payment processing uses KUBRA for one-time transactions.. Never enter account credentials into a lookalike site reached through an unsolicited message.

Telephone payment

Phone IVR

866-446-2516 for 24/7 one-time Aquarion payments. Customer service is 1-800-732-9678 Monday-Friday 8:00 a.m.-5:30 p.m.; the same customer-service number is used for 24/7 emergencies.

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

A dedicated this detail was not publicly posted. The reviewed Aquarion/Aquarion Water Authority pages publish portal, phone, mail, and assistance channels but do not expose a local text-to-pay keyword or enrollment workflow. The authority’s MuniOS transition may change digital features, so customers should use the current official portal rather than an unsolicited SMS link.

Mail-in address

Legacy Connecticut statements identify Aquarion Water Company of CT, PO Box 3664, Portland, ME 04104-3664, with another statement remittance panel identifying PO Box 9265, Chelsea, MA 02150-9265 depending on the service division. Because the public authority transition completed June 30, 2026, customers should use the remittance address printed on the current bill.

Counters, drop boxes, and office hours

Aquarion provides walk-in payment locations by service territory and directs customers to the official payment/billing pages for the location list. The reviewed current pages do not expose one consolidated 2026 address-and-hours table for every former Aquarion territory; customer service is at 1-800-732-9678 weekdays 8:00 a.m.-5:30 p.m. and emergency assistance continues 24/7.

Accepted digital instruments

What you can use online

The legacy Aquarion portal supports bank-account payment, AutoPay, paperless billing, usage history, and payment reminders. One-time payments accept a checking account or credit card online or by phone; the new authority links MuniOS for the post-transaction customer experience. The reviewed pages do not confirm Apple Pay or Google Pay.

2026 transaction pricing

Convenience fees

KUBRA charges a $1.95 service fee for one-time payments for Massachusetts customers and non-residential Connecticut/New Hampshire customers. The reviewed Connecticut residential pages do not state a universal online card fee; portal bank-account payments are described as free.

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 Authority 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.
