The Allegheny County Sanitary Authority (ALCOSAN) Board of Directors created the Green Revitalization of Our Waterways (GROW) program in a system-wide effort to reduce excess water from entering an already overloaded sewer collection system. The GROW program is now an essential part of ALCOSAN’s long-term plan to create cleaner waterways in compliance with regulations of the federal Clean Water Act and the Pennsylvania Clean Streams Law.

Immediately after the GROW program’s creation, the Authority began working with its 83-member municipalities and municipal sewer authorities that send wastewater to its treatment facility. Under the program, any municipality or municipal sewer authority within the ALCOSAN service area is eligible to submit a source control project for grant funding consideration.

The grants may be used to install green storm water infrastructure, remove streams from the sewer system, reduce the amount of water seeping in through groundwater or to separate out storm sewers. In addition to financial support, ALCOSAN provides technical expertise and other assistance to municipalities for the projects, all with the aim of removing unnecessary storm water and ground water from the system.

Since 2016, the GROW program has provided over $30 million in grant funding towards 105 projects that will reduce sewer overflow by an estimated 142 million gallons. 

When and How to Apply

Any municipality or municipal sewer authority within the ALCOSAN service area is eligible for GROW grants. New grant cycles typically begin in the Fall season.  ALCOSAN will schedule information meetings before each cycle to assist municipalities that need it for the application process. Application documents are available via the municipal portal

Green Stormwater Infrastructure Guidance Documents

ALCOSAN is committed to taking a proactive approach to stormwater management. ALCOSAN and its customer municipalities and authorities have completed significant work throughout the service area to understand the scope and challenges of preventing extraneous source flow from entering the Regional Conveyance System. Building on these efforts, ALCOSAN created guidance documents to support the successful implementation of Green Stormwater Infrastructure (GSI).  This document is intended to provide guidelines for private and public entities in constructing GSI, from initial planning stages to post-construction maintenance.
