New Rate Structure

Current Status

On July 18, 2018, WSSC Commissioners selected a new, four-tier water and sewer rate structure during the monthly Commission Meeting. The new structure will be effective July 1, 2019.

Bill Impacts

Based on the new four-tier rate structure, the average bill of a three-person household would decrease by $4.83 (based on average per person consumption of 55 gallons per day). Review other bill impacts. Customers are now charged only for the water used in each tier. Previously, customers were charged at the highest tier rate back to the first drop used.

Note: The bill impacts are illustrative only and based on FY18 revenue requirements. Final bill impacts will depend on final rates for FY20, which will be adopted in June 2019.


Public Outreach

Throughout the rate structure development process, WSSC engaged in an extensive public outreach campaign to garner input and feedback from residential and non-residential customers, elected officials and other interested stakeholders in both counties. In total, WSSC held or participated in more than 30 public meetings and/or hearings since spring 2017, which were attended by more than 1,500 customers and generated more than 300 total comments on the proposed rate structures. Additionally, all WSSC meetings were livestreamed and seen by nearly 2,500 viewers.
