Coraopolis Water & Sewer Authority

Welcome to Coraopolis Water & Sewer Authority

The Coraopolis Water and Sewer Authority (CWSA) was formed in 2005 to oversee the operation, maintenance and improvement of the Borough’s water and sewer system. While CWSA owns the drinking water treatment facility, the sewage treatment plant—the Riverview Sanitary Authority facility—is jointly owned by Moon Township and the Borough of Coraopolis.
