Two years and $20 million later, a flood-prone section of Maspeth has a new sewer system.

The city has finished replacing combined sewers, water mains and catch basins along 54th and Maurice avenues, Department of Environmental Protection (DEP) Commissioner Cas Holloway announced June 21.

The infrastructure project, started in August of 2008, targeted the section of 54th Avenue between Maurice Avenue and 58th Street, and Maurice Avenue between 54th and 56th avenues.

It was started in August of 2008, one year after severe flooding hit Maspeth and Middle Village. Since then, civic groups and elected officials have lobbied for a better sewer system.

The upgrade includes 35 new catch basins, 2,692 feet of new combined sewers, and the replacement of 3,392 feet of distribution water mains.

Holloway said it would “substantially reduce flooding in Maspeth, and ensure that the water supply network continues to deliver healthy, great tasting drinking water for years to come.”

The project is part of a larger effort to overhaul aging sewer and water distribution networks in Queens. The DEP has budgeted another $1.7 billion through fiscal year 2014 to carry out the work.

“Investments in our infrastructure make our communities safer, reducing sewage backups and providing our residents with a quality water distribution system they deserve,” said Councilman Jimmy Van Bramer. “The completion of this project marks a great day for Maspeth residents.”
