Nationwide Plumbers handles water main work in Brooklyn and across New York City: emergency water main breaks, new water mains and taps to the city main, water service connections, private fire hydrants, and sewer connections to the city sewer. Our water main and sewer crew does the street excavation, and we handle the NYC DEP and DOT permits, so property owners and builders deal with one licensed company from the first call to the final inspection.
Emergency water main service, 24/7
When a water main or service connection breaks, water can flood a basement, undermine a sidewalk or shut down a whole building. Call 718-748-2727 any time. Our dispatch sends a crew, the water is shut off at the right valve, the area is made safe, and the repair is planned and permitted.

Permits and city coordination
Water main and street work in New York City needs the right permits before anyone digs. We coordinate the NYC Department of Environmental Protection (DEP) water and sewer connection approvals, the Department of Transportation (DOT) street opening permits, and the Department of Buildings (DOB) plumbing filings when they apply, plus utility mark-outs before excavation.
Who we work for
- Homeowners with a broken water service or a DEP notice
- Builders and developers who need new water and sewer connections for a new building
- Property managers with multifamily, commercial or mixed-use buildings
- General contractors who need a licensed water main and sewer sub on their job
Water main or water service line?
The city water main runs under the street. The water service line is the pipe from that main into your building, and in New York City the property owner is generally responsible for it. For repairs or replacement of the line from the curb to your meter, see our water service line page. For work at the main itself, new taps and street connections, this is the right page.

Water Main Repair, Installation and Emergency Service in NYC: FAQ
What should I do if a water main breaks at my property?
If water is coming up through the sidewalk, street or basement, shut the building's main valve if you can reach it safely and call 718-748-2727 right away, 24/7. If the break is in the street, also report it to 311 so NYC DEP can respond.
