GROW-ing our Region

ALCOSAN is committed to helping the region GROW. When I say “grow” at ALCOSAN, I’m not just referring to the economic growth and the growth of recreational opportunities that are dependent on the clean water produced at the wastewater treatment plant. I’m talking about GROW, the Green Revitalization of Waterways program.

ALCOSAN’s Board of Directors created the GROW program in June of 2016 and the staff immediately began working with its 83 member municipalities and municipal sewer authorities to make them aware of the program and how to participate. By January of 2017, the first round of GROW grants worth $9 million were awarded for 30 projects in 16 municipalities and including nine Pittsburgh neighborhoods.

Last month, the board issued the second round of grants, also worth $9 million. This time, 29 projects in 25 municipalities, including four Pittsburgh neighborhoods, were included.

Combined, both cycles of GROW grants are expected to remove nearly 110 million gallons of stormwater and groundwater from the ALCOSAN system annually.

The third funding cycle will begin in February 2018, and ALCOSAN already is scheduling informational meetings to assist municipalities that need it in the application process.

The grants may be used to install green storm water reduction technology, remove streams from the sewer system, reduce the amount of water seeping in through groundwater or separate out storm sewers. In addition to new projects, some completed projects that were constructed after 2014 also were eligible for consideration for reimbursement.

In addition to financial support, ALCOSAN provides technical expertise and other assistance to municipalities for the projects, all with the aim of removing unnecessary stormwater and ground water from the system because it triggers unsanitary overflows.

The GROW program is an essential part of ALCOSAN’s long-term, green-first plan to create cleaner waterways in compliance with regulations of the federal Clean Water Act and the Pennsylvania Clean Streams Law and to help the municipalities in the ALCOSAN system fulfill their responsibilities under the Pennsylvania Department of Environmental Protection and the Allegheny County Health Department.
