A new rate structure for all 1.8 million WSSC customers in Montgomery and Prince George’s counties (Maryland) was approved to go into effect July 1, 2019.
Maryland Public Service Commission (PSC) directed the change after ruling WSSC’s current 16-tier structure to be unreasonable because it was unduly preferential to low-usage customers.
The new, combined water/sewer volumetric rate structure is intended to better align costs with rates, reflect customer and Commission rate-setting policy goals and objectives, and provide a more predictable revenue stream to pay for infrastructure improvements. Additionally, customers will be charged only for the water used in each tier, versus being charged at the highest tier of water used, back to the first drop of water.
Approximately 93 percent of all WSSC bills are for residential customers. Lower quarterly bills are expected for households using the average water consumption of 55 gallons per person, per day. wsscwater.com
