Brooklyn Water Main Extension Experts

Sewer & Water Pros is Brooklyn's trusted water main extension contractor. Whether you need a new water tap for new construction, a larger water service for a building expansion, or a water main extension for an ADU, we handle the complete process. Our team has installed hundreds of water main extensions across Brooklyn — from DUMBO to Coney Island, from Greenpoint to Bay Ridge. We work directly with NYC DEP to ensure your water main extension meets all current requirements.

Brooklyn Water Main Extension Process

A water main extension in Brooklyn involves tapping into the city water main in the street and running a new water service line to your property. The process requires a DEP water tap permit, DOT street opening permit, and coordination with existing utilities. Brooklyn's dense infrastructure means careful planning is essential. Our licensed team handles all permitting, excavation, pipe installation (copper or ductile iron), connection to the city main, backfill, and street restoration.

Types of Brooklyn Water Main Extensions

We perform all types of water main extensions in Brooklyn: new water taps for construction, water service upgrades (from 3/4" to 1" or 2"), fire sprinkler water connections, commercial water service installations, multi-family building water mains, and domestic water service extensions. Each project includes a free site survey, detailed estimate, full permitting, professional installation, and DEP inspection coordination.
