Pay your bill or manage your account

Great Salt Bay Sanitary District is excited to offer residents an easy, convenient and secure method to pay your water and sewer bills online through the customer portal (more info below). Make a one-time payment or sign up for autopay with credit/debit card or e-check. Visa, MasterCard, Discover American Express are accepted forms of credit/debit card payment. A convenience fee of 2.25% will be charged for all credit/debit card transactions and $1.25 for all e-checks. Balances over $800.00 will need to be processed as multiple transactions using a credit/debit card, or can be processed in a single transaction using an e-check. Because of the $800.00 transaction cap for using credit/debit cards, autopay will not process balances over $800.00 for this payment method, so it is recommended you use the e-check payment method.
