Wastewater Management

The Hempfield Township Municipal Authority (THTMA) currently provides sewage service to a total of 13,283 residential, industrial, and commercial customers.

Our goal is to collect, convey, and treat wastewater (aka sewage) – and transform the raw sewage into clean, clear water for discharge back into the environment. 

If you have a question or concern not answered by our website, contact THTMA today. 

For information of general interest to Hempfield residents and businesses, please visit the Hempfield Township website.

Notice Regarding Sewage Backup


To Our Customers:  The Hempfield Township Municipal Authority would like to respectfully notify you that property damage resulting from sewage backing up into your home is the responsibility of the homeowner, not the Authority.

Most insurance companies offer products to protect homeowners from a sewer backup. Protect yourself from a sewer backup by contacting your insurance agent. Furthermore, there are mechanical devices (backwater valves) designed to prevent sewage back-ups available from local plumbers.  

We hope you will take the time to consider your risks and select any options you feel best protect your property. If tenants occupy your building, please advise them of this notice.
