This calculator will only work for customers who receive a bill for both water and sewer service. - en Español
Effective July 1, 2019 a new, modern and simplified rate structure will change the way WSSC charges for water and sewer. We’re also improving the way your bill looks so it is easier to understand.
A rate structure is how you are charged for water and sewer. The amount charged is the rate. To fund needed infrastructure repair and replacement, a proposed revenue increase will accompany the rate structure change effective July 1, 2019. Most customers will see an increase in their bills, but about 30 percent of WSSC customers will see a decrease. The decrease is because the new rate structure charges for water used within each tier instead of charging for all water use at the highest tier.
A typical residential customer (family of three using 15,000 gallons over 91 days) will see their bill go up by about $4. This calculator will help you compare your current bill to what a bill for the same amount of water use will be after July 1, 2019.
Instructions: To use the calculator, you’ll need a copy of a current bill you received between July 1, 2018 and June 30, 2019. Using your bill, fill in the five blanks below — just like you see them on your bill. Then scroll down to see what your bill will be in the future.
You may have questions, and we’re here to help. We’re available to talk through the changes at 301-206-WSSC (9772). For water-only customers, and customers with submeters, please call Customer Service to talk with an agent to help you estimate your bill.
Disclaimer: This online calculator is provided as a convenience to help you better understand how your bill will be impacted by the new rate structure effective July 1, 2019. The fiscal year 2020 rates have not yet been adopted by the Commission. Therefore, your actual water and sewer charges may differ from those displayed in this calculator. In the case of any discrepancy between your actual bill and that calculated by this tool, the amount indicated on your bill prevails.
