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 Brooklyn, our team has completed thousands of water main extension projects across all 84 neighborhoods.

"Our 80-year-old sewer line collapsed and we were in a panic. Sewer & Water Pros came out the same day, got the DEP permits fast, and had a brand new line installed in 4 days. The street restoration was perfect — you can't even tell they were there. Best contractor experience I've ever had in NYC."

"I was dreading having my whole yard dug up for a sewer repair. Sewer & Water Pros suggested trenchless pipe lining and it was a game changer. They fixed the entire line through just two small access points. Saved my landscaping and it cost less than traditional excavation. Amazing technology and skilled crew."
