Fourteen of Allegheny County Sanitary Authority’s (ALCOSAN) partner municipalities and municipal authorities have been offered over $22.6M in Green Revitalization of our Waterways (GROW) grants in the program’s sixth round. These 15 projects make up the largest collective award amount since GROW’s inception and are modeled to remove 62.8 million gallons of overflow volume.

Created by ALCOSAN in 2016, the GROW program helps the Authority’s customer municipalities and municipal authorities fund meaningful source control projects that help keep water out of the sewer systems.

This year’s group of awards includes a $10M grant to Pittsburgh Water and Sewer Authority (PWSA) for a stream removal project as part of its Four Mile Run Stormwater Improvement Project; and approximately $5.4M to the Borough of Baldwin for a sewer lining project along Streets Run. This project is unique in that it is a partnership between the borough and Brentwood, PWSA, West Mifflin, and Whitehall to improve a multi-municipal sewer line.

“This GROW cycle is a great example of how important it is to work together toward a common goal – keeping excess water out of our sewer systems,” said Arletta Scott Williams, ALCOSAN’s Executive Director. “We are always thrilled to be able to help fund these necessary source control projects in our customer municipalities.”

Including this cycle, ALCOSAN’s GROW program has offered grants in excess of $60M for approximately 140 projects, leveraging an approximate $53M in municipal, authority and third-party funding. In all, those projects are expected to reduce the volume of overflows into the region’s waterways by more than 200 million gallons. 

Any municipality or municipal sewer authority within the ALCOSAN service area is eligible for GROW grants. The seventh cycle will begin later this year, and ALCOSAN already is scheduling informational meetings to assist municipalities in the application process.
