Payment channels

Pay Boston Water and Sewer Commission (BWSC)

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 Paymentus; BWSC also provides a Customer Self-Service portal and QuickPay.. Never enter account credentials into a lookalike site reached through an unsolicited message.

Payment guidance

Choose the payment channel that fits your deadline

The safest payment path is the one published by Boston Water and Sewer Commission (BWSC) 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.
