We’ve made improvements to the layout of your water/sewer bill to make it easier to read and understand. Our goal is to provide clearer details about what you owe, when it’s due and how your charges are calculated. The updated layout highlights key information, organizes charges more clearly and shows how payments and credits affect your total balance. 

Review the following sample bill to see what’s new and how each section helps you quickly find the information you need.

2026 WSSC Water bill revisions are: Page 1, we added a box for "What Do I Owe and When Do I Pay?" This box includes your last bill balance, previous payments or credits, balance forward, current charges, and total due. Your total due is repeated to the right of this information, in bold black text, along with when this amount is due. On page 2, we've added a box under "Billing Details" that lists your balance forward, last bill balance, previous payment amount and receipt date, and other credits.
