Maryland American Water Granted New Rates by Maryland Public Service Commission
Increase Supports $22 Million in Completed Infrastructure Investments;
First Rate Adjustment Since 2019
Bel Air, Md. (March 2, 2026) –The Maryland Public Service Commission (PSC) has approved a settlement for new water rates for Maryland American Water. The approved rates represent a total annualized revenue increase of approximately $2 million.
The company’s rate request was filed on August 1, 2025, and supports approximately $22 million in completed capital and infrastructure investments in treatment system and distribution improvements since its last approved rate request in 2019.
“We are committed to making the necessary investments to continue the high-quality service our customers expect and deserve and ensure compliance with state and federal regulations,” said Laura Runkle, President, Maryland American Water. “Our capital planning approach to consistent and efficient investment helps improve water service reliability for the 24,000 people we serve.”
The new rates will be implemented over two years. Effective February 26, 2026, residential customers in the Town of Bel Air using 4,000 gallons per month will see their average bill increase by approximately $10 per month. On January 1, 2027, their bill will increase by another $10 per month. In the Severn District, residential customers previously billed a quarterly flat fee will transition to a monthly flat fee, which will increase by approximately $1.50 per month effective February 26, 2026. This is the first rate adjustment since 2019.
Maryland American Water also supports various important customer affordability programs by providing customers with bill paying assistance programs, payment arrangements and budget billing options, all available on the customer MyWater portal at marylandamwater.com. Income-eligible customers may also apply for assistance through the company’s H2O Help to Others program, administered by Dollar Energy Fund.
