First Envision-verified Wastewater Treatment Plant in the U.S. Receives Envision Silver Award

The Institute for Sustainable Infrastructure (ISI) announced today that the New York City Department of Environmental Protection’s (DEP) ongoing $150 million upgrade of Brooklyn’s 26th Ward Wastewater Treatment Plant (WWTP) recently earned the Envision sustainable infrastructure rating system’s Silver award. The DEP project is the first wastewater treatment plant project in the U.S. to receive an ISI Envision rating system award, and is the seventh Envision-verified infrastructure project overall in North America.

The DEP 26th Ward Wastewater Treatment Plant’s $150 million project upgrades the plant and provides critical redundancies to ensure it remains in a state of good repair for decades to come. New York City’s DEP will be adding a fifth preliminary treatment tank and will be installing new energy efficient and durable main sewage pumps, process air blowers and LED lighting. Additionally, a green roof will be added to the facility, large blowers will be put indoors to reduce noise, and all materials will be reused and recycled whenever possible. As the facility is located adjacent to Hendrix Creek and Jamaica Bay, the design for all the new structures, as well as the location and installation of critical equipment, follows guidelines outlined in DEP’s Wastewater Resiliency Plan and meets stringent and updated FEMA Advisory Base Flood Elevation regulations. The ongoing project work is taking place pursuant to an agreement between the New York State Department of Environmental Conservation (DEC) and New York City, with Greeley and Hansen as the design lead on the project.

The main objective of the project is to provide primary treatment redundancy and uniform grit distribution at the preliminary settling tanks during wet weather events, along with associated structural, architectural, electrical and instrumentation upgrades.

For complete details including specifics about the four highest-rated Envision measurement categories the project scored (Climate and Risk, Quality of Life, Leadership, and Natural World), read the press release.
