Green Infrastructure for Combined Sewer Systems

GI technologies treat stormwater as a resource, not something to eliminate. Also known as low-impact development or adaptive management, these techniques capture, infiltrate, treat and reuse polluted runoff before it enters the sewer system. GI offers environmental, social, and economic benefits. It can increase property values, beautify neighborhoods, cool extreme summer temperatures, support natural habitat, create local green jobs, and enhance public space.

Green Infrastructure practices include:

  • rain gardens

  • porous pavement/asphalt

  • green roofs

  • infiltration planters

  • trees and tree boxes

  • rain barrels

  • rainwater harvesting for non-potable uses such as toilet flushing and landscape irrigation

Green Infrastructure Municipal Outreach and Technical Assistance Program

The GI Municipal Outreach And Technical Assistance Program is a partnership between the Passaic Valley Sewerage Commission (PVSC) and Rutgers University Cooperative Extension Water Resources Program to pilot an outreach and technical assistance program providing guidance and direction to the 48 municipalities in the PVSC service area regarding the benefits and opportunities of implementing green infrastructure practices.

Targeted efforts are needed for the management of stormwater runoff using green infrastructure so that municipalities can begin to alleviate localized flooding, protect and improve water quality, reduce inflow and infiltration and combined sewer overflows to local waterways. Through education, outreach, and community-driven demonstration projects, the program partners are providing municipalities with information they can use to make practical, science-based, and cost-effective decisions about water, wastewater, and stormwater management to improve the quality of life of residents while protecting the water resources of the region.
