New Rate Structure

A rate structure is how you are charged for water/sewer services. A rate is the amount charged. Effective July 1, 2019, we are implementing a new, modern and simplified rate structure that more closely aligns customer rates with the cost of providing service.

Understanding Your Bill

A modern, simplified rate structure that’s equitable for all 

The new four-tier rate structure replaces the 16-tier structure, which has been in place for more than 25 years. A lot has changed in that time – water use habits, average demand, peak day water usage – so we modified the rate structure to reflect how customers use water today. We changed the amount of water use in each tier and the price per tier so that:

  • The first tier captures what a family of three uses for basic sanitary household needs.
  • The second tier captures what a family of three uses for an average of 55 gallons per person/day consumption, enough for basic sanitary household needs and outdoor water use (or 165 gallons/day for the household).
  • The third tier supplies enough water for a 5-person household.

Our efforts to change our rate structure began in 2012 with a rate study and several changes, but in 2017 the Maryland Public Service Commission determined that the old rate structure was unfair to customers who use greater than average amounts of water. Our new rate structure ensures rates are fair and equitable for all WSSC Water customers and aligns more closely with the cost of providing service.

Your water bill funds safe, reliable water


On a per person basis, WSSC Water customers have reduced the amount of water they use over the past 25 years, and we expect to see per capita water use continue to decline in the future. The new rate structure was developed to accommodate changing customer demand while also helping customers save money by encouraging wise water use.

The new tiered rate structure is commonly used by water utilities across the country to encourage conservation because the more water customers use the more they pay. The Maryland Department of the Environment specifically encourages an increasing block rate structure for water conservation.
