Biodiversity & Ecosystem Restoration

Going the Extra Mile to Protect Local Habitats

Local ecosystems are highly interrelated and delicate structures. Our commitment to biodiversity promotes restoration of ecosystems and protection of threatened and endangered plants and animals in and around our treatment sites and intake structures.

44 acres of our New Jersey property will be used to restore wetland functions

236 sensitive sites have been identified for further study

Wetland Mitigation Project at Closter & Haworth, NJ

Several years ago, Hurricane Sandy caused significant damage to the wetlands in our Closter and Haworth, NJ locations. The wooded properties had been impacted by wind damage to trees, which can spread insects and disease. We felt an obligation to help restore the lands to their natural state, so we engaged an environmental consulting group called Greenvest to help us come up with a plan.

The improvements we have been making to the area include controlling invasive and toxic vegetation, clearing debris and planting trees and shrubs—as well as annual visits to monitor and maintain the land. Our goal is to restore the impacted wetlands, preserving their rich biodiversity and even improving the quality of the water.

Connecticut River Action Plan by Springfield, MA

Our Springfield, MA operation has developed a sustainable action plan for the Connecticut River corridor, with activities necessary to respond to overflow events at the combined sewer overflow (CSO) stations.

To reduce overflow discharges to the Connecticut River, we have installed a CSO monitoring system that provides remote real-time monitoring of wastewater depths and flow velocities at individual CSO stations throughout the system.

These data allow us to analyze the condition of the sewer collection system, enabling early identification of warning events and estimation of quantity and frequency of discharges. This allows SUEZ North America to set appropriate emergency response measures to stop the overflow condition and restore normal system function.

Broadening the Definition of Sensitive Sites

In order to deepen our commitment to the environment, we chose to broaden our definition of what constitutes an environmentally sensitive site. In 2014 we made a huge step forward in protecting local biodiversity and ecosystems by increasing the number of environmental action plans tenfold—from 18 to 124!
