West Mifflin Sanitary Sewer & Stormwater Authority is currently servicing 146 miles of sanitary lines and 50 miles of stormwater lines. We also service and manage 14 different pump stations, and 2 sewage treatment plants.
The purpose of these pumping stations is to receive the sewage from local areas and pump it onward toward our treatment plants, that will then begin to process the sewage. You can learn more about the treatment processes, and how it all works on the Wastewater Tab.
WMSSSA and our Engineers are continually working to evaluate our infrastructure to help prevent and reduce emergency repairs, improve system reliability, protect the environment, and provide dependable service to all of our customers.
We are currently working on different projects within the Borough. Some of which were made possible with the help of Grant Funding. WMSSSA is actively pursuing available grant opportunities to assist in some of these upgrades and improvements. While grant funding can provide support, not all projects receive this type of funding. The Authority continues to prioritize necessary upgrades and improvements to our systems to maintain reliable, efficient, and sustainable services for the community.
Please continue to check back for updates on ongoing projects and awarded grants.
