Water Main Installation for New Buildings

Installing a water service for new construction differs from replacing an existing one. New building water service requires approved plans, multiple agency sign-offs and strict adherence to NYC Department of Environmental Protection (DEP) standards. Our specialized team handles:

  • Permit coordination: We manage DEP water tap applications and permits, as well as DOT street opening permits and cross-connection approvals to reduce delays.
  • Capacity planning: Our plumbers review fixture counts to determine proper pipe diameter and tap size for residential or commercial installations.
  • Excavation and installation: We excavate controlled trenches from your building foundation to the city main and install Type K copper or ductile iron piping per specifications.
  • Inspection compliance: DEP field inspections occur at critical stages. Our crew schedules these proactively to avoid holdups.
  • Full restoration: Once inspections are complete, we backfill trenches, perform compaction testing and restore sidewalks.

From initial permit application to final DEP sign-off, our crew maintains consistent communication with your construction team. We coordinate DEP wet connection installations, schedule inspections and manage street opening permits with precision. We’ve completed water main installations for new buildings throughout NYC, including single-family homes, townhome developments, and apartment complexes across Brooklyn, Queens, Manhattan and the Bronx.

Commercial Water Main Installation for Multiunit Projects

Larger developments require coordination of multiple underground utilities, often involving higher-capacity water services with multiple taps or combined mains. These commercial water main installation projects include apartment buildings and properties throughout the city.
