Randy E. Hayman, a partner in a Washington environmental law firm, has been appointed Philadelphia’s next water commissioner, Mayor Jim Kenney announced Monday.

Starting June 24, Randy E. Hayman will run the Water Department and oversee its 2,000-member staff. The department provides drinking water from the Schuylkill and Delaware River to city residents from three plants. It also treats sewage and storm water, oversees operations of 3,200 miles of water mains, 3,700 miles of sewers, and 25,000 fire hydrants.

Hayman is a partner at Beveridge & Diamond. He has also served as an attorney for the District of Columbia Water and Sewer Authority and the Metropolitan St. Louis Sewer District.

Hayman will replace Debra McCarty, who retired April 5. He will be paid $200,000 a year.

“I am thrilled to welcome Randy to Philadelphia to take the helm at the Philadelphia Water Department,” Kenney said in a statement. “Our Water Department provides residents with top-quality tap water and is a regional champion in the protection and enhancement of the Schuylkill and Delaware Rivers, the city’s drinking water sources. I am confident Randy will be able to continue the department’s record of success, and I look forward to working with him to continue to maintain our high-quality water infrastructure.”

Hayman said he was “honored to be given the opportunity to lead the Philadelphia Water Department” and called it a "national leader in water, wastewater and storm-water management.”
