Brooklyn's $150M upgrade to 26th-Ward WWTP garners ISI Envision award
The Institute for Sustainable Infrastructure has recognized the New York City Department of Environmental Protection's ongoing $150-million upgrade of the Brooklyn 26th-Ward Wastewater Treatment Plant with the Envision sustainable infrastructure rating system's Silver award.
Aug. 25, 2015 -- Today, the Institute for Sustainable Infrastructure (ISI) announced that it has recognized the New York City Department of Environmental Protection's (DEP) ongoing $150-million upgrade of the Brooklyn 26th-Ward Wastewater Treatment Plant (WWTP) with the Envision sustainable infrastructure rating system's Silver award. The upgrade serves as the first WWTP 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 endeavor is providing critical redundancies to ensure that the plant 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 26th-Ward WWTP is located in southeastern Brooklyn on a 57.3-acre site and serves approximately 283,000 residents in East New York, Canarsie and Brownsville. It has the capacity to receive, clean and disinfect up to 170 million gallons per day of combined sanitary and stormwater flow. As part of an agreement with DEC, DEP engaged Greeley and Hansen to design the project that would add to the plant's preliminary treatment tanks and modify the high-level sewage pumps, pump and blower house, sludge de-gritting wing, and other work.
The main objective 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.
