Need to extend your water main to reach a new building, addition, or a different connection point on the city water main? Sewer & Water Pros specializes in water main extensions across all five NYC boroughs. A water main extension involves running new water service pipe — typically copper — from the city water main in the street to your property. This is required for new construction, building additions, properties converting from well water, and situations where the existing water main route needs to be rerouted. We handle the complete process: DEP tap application, DOT street opening permit, excavation from the city main to your building, new copper pipe installation, pressure testing, DEP final inspection, and full street and sidewalk restoration. Our team has completed hundreds of water main extensions in NYC, working through every type of soil condition, around existing utilities, and under busy city streets. We coordinate with Con Edison, National Grid, and other utilities to ensure a safe, efficient installation.
In Manhattan, our team has completed thousands of water main extension projects across all 80 neighborhoods. We understand the unique challenges of working in Manhattan, including the specific underground conditions, local regulations, and the importance of minimizing disruption to residents and businesses. Our Manhattan crews are experienced, efficient, and committed to delivering quality results on every project.

"Sewer backup on a Sunday night — not fun. Called Sewer & Water Pros and they had a crew at our building within 2 hours. They did a camera inspection, found the blockage, and cleared it that night. Then came back Monday to do a full repair. Saved our restaurant from a health code nightmare."
David K. — Upper East Side, Manhattan
"Water main leak was flooding our basement. Sewer & Water Pros responded within an hour, shut off the water, and had the repair done by the next morning. They coordinated with DEP and Con Ed seamlessly. Their emergency service is the real deal — fast, professional, and fairly priced."
