Water main installation in Yonkers, NY

New water main connections for construction, additions, and bigger supply needs.

New construction, major additions, and conversions to multi-family use often require a new or larger water main connection. Water main installation brings a properly sized supply line to the building, coordinated with the water utility and inspections, so the property has reliable service from day one.

Sizing a new water main

The size of a water service depends on the number and type of fixtures in the building, the distance from the street, elevation changes, and available street pressure. Multi-family buildings, commercial spaces, and homes with extensive irrigation or fire sprinklers may need larger services. Undersizing leads to pressure problems; oversizing adds unnecessary cost.

We calculate demand based on the building's plans and work with the utility's requirements to determine the right size.

Coordinating the work

Water main installation often involves street or sidewalk openings, utility tapping, meter setting, and inspections. Timing depends on permits and utility scheduling. We coordinate with contractors, the utility, and inspectors to keep the project moving.
