Chester Water Authority Announces New Executive Manager, Celebrates One-Year Anniversary of Award-Winning, Affordable Water Under Minority Majority Board

Chester Water Authority (CWA) is proud to commemorate the one-year anniversary of its groundbreaking minority majority board, a milestone that coincides with the organization’s continued commitment to providing award-winning, affordable public water services to its over 200,000 residents and businesses in Chester County, Delaware County, and the City of Chester. 

In November 2022, a new CWA board was appointed with a majority composed of individuals from underrepresented backgrounds (6 of the 9 board members), a decision that has proven instrumental in steering the organization toward inclusivity, equity and innovation. This diverse board has been invaluable in contributing to CWA’s mission of ensuring affordable public water is accessible for all residents, taking into consideration the special needs of ratepayers of color.
