(Maspeth, NY - October 7, 2024) The NYC Department of Environmental Protection (DEP) and the NYC Department of Design and Construction (DDC) today announced the completion of a $106 million infrastructure project in Maspeth, Queens that is the second of three that are creating a new drainage network through central Queens. The project also upgraded over a mile of water mains and replaced smaller, local combined and sanitary sewers. DDC managed the project for DEP and DOT, and successfully used micro-tunneling technology throughout large parts of it to minimize construction impacts during work.

The project is the second in a series of three that is creating a major new drainage network through central Queens. And connects at several points to work that was previously completed by DDC in parts of 69th Street and Calamus Avenue in Middle Village. That earlier $19.5 million project, which installed 2,600 feet of new sewer using open trench construction, created excessive noise and disruptions for local residents and was halted early, with the remaining work moved to the recently completed project so that micro-tunneling could be employed.

The third project is currently being designed in-house at DDC and is expected to start construction in mid-2026 with an estimated budget of roughly $80 million. That project will connect with the recently completed work at the Long Island Expressway and extend the new drainage system south to roughly Juniper Boulevard South.

"This $106 million project is part of DEP's commitment to building a new drainage network through Central Queens, which will alleviate the flooding caused by extreme weather," said DEP Commissioner Rohit T. Aggarwala. "We will continue to partner with DDC and DOT to invest in infrastructure upgrades that create more resilient communities, allowing us to better manage stormwater and protect our residents from climate change."

"When the first project in this important new drainage system proved too disruptive to the community, DDC stopped work, changed its approach and used micro-tunneling instead, including in a very sensitive and busy area where crews tunneled under Queens Boulevard," said NYC Department of Design and Construction Commissioner Thomas Foley. "With projects like these, plus the massive Southeast Queens Initiative, DDC, DEP and DOT are investing billions of dollars in Queens drainage and street upgrades."

Overall, the project installed about 3,625 feet of new 96-inch diameter combined sewer plus about 900 feet of new box sewers up to 12 feet by 8 feet and about 300 feet of 84-inch HOBAS sewers. Additionally, approximately 1,300 feet of combined sewer were replaced. About 5,500 feet of water mains up to 90 years old were replaced with new ductile iron pipes, a more durable material.

One location where micro-tunneling was particularly effective is where the new sewer crosses under Queens Boulevard. Engineers estimated it would have taken months and many pedestrian and traffic disruptions to relocate underground utilities that are already in the street and then install the new sewer. Instead, micro-tunneling reduced construction time at the Queens Boulevard location from several months to roughly one week.

Local catch basins and fire hydrants were upgraded and nearly 1.5 miles of local curbs were replaced along with sidewalks in many areas. The project also upgraded 47 pedestrian ramps to be ADA-compliant, and added 18 trees and a bike lane in the area.

"The need to upgrade our sewer infrastructure is more pressing than ever," said Councilmember Robert F. Holden. "Thanks to the City for completing the second phase of this massive sewer project, and I look forward to the third and final phase being completed in the coming years to finally give residents some relief."

"The families of Maspeth deserve to live free from flooding every time it rains, and this critical project will go a long way toward protecting homes and businesses across this community," said Queens Borough President Donovan Richards Jr. "Thank you to our partners at DDC for getting this work done in a way that was as least disruptive to area residents as possible, and I look forward to completing the third and final phase of this project in the years to come."

"I am happy to see the completion of this infrastructure project here in Maspeth," said Assemblymember Steven Raga. "It is incredibly important that our city's design meets the needs of residents, and this new drainage system and additional upgrades will better serve Queens residents. I appreciate DDC responsiveness to community concerns throughout the installation of this new system and look forward to the completion the third and final project in near future."

About the NYC Department of Environmental Protection
DEP manages New York City's water supply, providing approximately 1 billion gallons of high-quality drinking water each day to more than 9 million residents, including 8.3 million in New York City. The water is delivered from a watershed that extends more than 125 miles from the city, comprising 19 reservoirs and three controlled lakes. Approximately 7,000 miles of water mains, tunnels and aqueducts bring water to homes and businesses throughout the five boroughs, and 7,500 miles of sewer lines and 96 pump stations take wastewater to 14 in-city treatment plants. DEP has a robust capital program, with a planned $31.3 billion in investments over the next 10 years that will create up to 3,000 construction-related jobs per year.
