Partnership for Safe Water

Formed in 1995, the Partnership for Safe Water is a voluntary cooperative effort among the Environmental Protection Agency (EPA), the Pennsylvania Department of Environmental Protection (PA DEP), the American Water Works Association (AWWA), and other drinking-water organizations and water suppliers across the nation. The goal of the Partnership is to enhance the quality of drinking-water safety by optimizing treatment plant performance.

A water supplier that is a member of the Partnership commits to a standard of performance that is higher than that required by federal rules and regulations. Chester Water Authority is a member.

Grassroots Community Outreach: Save CWA

At the May 18, 2017 CWA board meeting, the Authority’s board voted unanimously to reject AQUA’s offer of $320M to buy the Authority. The board has been fighting tirelessly against a hostile takeover ever since, saving ratepayers $276M and counting. Ratepayers across the service area have organized to help Save CWA — delivering yard signs, going to public meetings, canvassing with petitions, writing and visiting elected officials and more. Join other ratepayers in this fight at
Chester Water Authority’s sole purpose is to provide excellent-quality water to our residential, business, and industrial customers. As a municipal authority, CWA does not have stockholders who require dividends. That means our rates are – and can remain – lower than those of private utility companies. Equally important, CWA has a higher percentage of funds to direct into the infrastructure to make capital improvements such as storage tanks, rehabilitating and repairing existing mains and lines, and reinforcing the distribution system.

CWA, as your regional water authority, sets goals that are dedicated to meeting the needs of the communities we serve in Delaware and Chester Counties. Being totally integrated into the region, we transcend county boundaries. Through capital projects and proactive maintenance, CWA invests in our water treatment and distribution infrastructure to deliver quality, service, and value to the community. CWA is part of your community. We are your neighbors and friends.

People Impacted By A Sale

Chester Water Authority has 45,127 direct residential and commercial customers in southern Chester County and western Delaware County including the City of Chester. CWA also provides water to Rising Sun, Maryland and northern Delaware.
