Coraopolis Water and Sewer Authority (CWSA)


In Coraopolis, we like to stay informed and up-to-date on what is happening. Understanding water rates and water quality reports can be complicated, so we have amassed as much information as we could find, below. In addition to this information, the CWSA holds monthly meetings at the borough building which are open to the public. These are held on the 3rd Wednesday of each month starting at 6:30 p.m.

Water Quality

Everyone wants to be sure that the water they are using is safe. The CWSA is fully compliant with the EPA's Safe Water Drinking Act (SWDA) and provides annual reports detailing exactly what is in the water we drink. These can be found here:

If you would like some background on what you should be looking for when you read these water quality reports, the National Sanitation Foundation website does a great job of explaining how an average citizen can best understand these reports here.

Understanding your rate


When you get your bill, the number at the bottom is actually the amount you owe for water, sewer, and garbage combined. When comparing your rate to other water authorities in Allegheny County, be careful because some of them may bill these charges out separately. In 2014, Robinson Twp published a comparison which can be found here and shows that, while Coraopolis has the highest rate in the area for water cost, we have one of the lower rates for sewage.

Borough Of Coraopolis Pollutant Reduction Plan

As part of compliance with the Coraopolis Water and Sewer Authority Separate Storm Sewer System (MS4) Permit, a Pollutant Reduction Plan (PRP) has been developed for submission to the Pennsylvania Department of Environmental Protection.  The PRP proposes implementation of Best Management Practices to reduce discharge of sediment and/or nutrients to impaired surface waters within the municipality.  Once implemented, it is anticipated that the cost of complying with this state-mandated plan will need to be funded via a stormwater fee assessed to borough residents. The PRP was made available for public review and comment at the Coraopolis Water and Sewer Authority Office, 1012 Fifth Avenue from July 31 through August 30, 2017, during which time written comments were accepted.
