Plumbing

Water in. Waste out. Designed properly.

Domestic water, drainage, storm water, rainwater harvesting and STP/ETP integration — engineered for water budget, code compliance and decades of uninterrupted service.

What we deliver

Plumbing is more than pipes. Get it wrong and you discover, three monsoons in, that the storm drains undersized for actual Indian rainfall.

Indian industrial plumbing sits at the intersection of water-budget pressure, monsoon load, NBC and pollution-control compliance, and operational uptime. We engineer around four real constraints: peak demand, drainage gradient and venting, storm capacity at 1-in-50-year rainfall, and the wastewater scheme the site will actually operate.

Plumbing is integrated with fire-water storage, rainwater harvesting and STP/ETP in one hydraulic strategy — so tanks aren't built twice and pump rooms aren't sized for systems that never run together.

Plumbing scope at a glance

What a typical plumbing EPC scope covers

  • Cold & hot water supplyUnderground & overhead tanks, pumping, distribution, hot water generation and circulation.
  • Drainage & wasteSoil, waste, vent stacks, traps, gradients — IS 1742 / NBC compliant.
  • Storm water & rainwater harvestingRoof drainage, surface drains, recharge pits, percolation, IGBC-compliant water reuse.
  • STP / ETP integrationSewage and effluent treatment plant inlets, pumping, treated-water reuse routing.
Plumbing sub-systems

Six sub-systems, designed as one.

Each sub-system carries different code, capacity and uptime constraints. We engineer them as one hydraulic scheme so they share infrastructure where they should and don't where they shouldn't.

01

Domestic water supply

Underground & overhead tanks, transfer and booster pumping, distribution mains and risers, point-of-use isolation and metering.

02

Hot water generation

Solar, heat-pump, gas-fired or electric — sized to peak demand profile, with recirculation to keep dead-leg temperatures safe.

03

Drainage, waste & venting

Soil, waste and vent stacks, traps, manholes, inspection chambers — gradients and pipe sizing to IS 1742 / NBC.

04

Storm water management

Roof drains, surface drains, retention tanks, discharge connections — sized to local rainfall intensity, not generic catalogue numbers.

05

Rainwater harvesting

Catchment routing, first-flush diverters, filtration, recharge wells, percolation pits — designed for IGBC / LEED credits where the target applies.

06

STP / ETP integration

Sewage and effluent treatment plant inlets, pumping schemes, treated-water distribution for flushing, irrigation and cooling tower make-up.

Standards we engineer to

Codes & standards, including the local pollution control rules.

Plumbing compliance is the most locally-varying of the four disciplines. We design to the national codes and the specific state or municipal rules that govern your site.

NBC 2016 Part 9

Plumbing services chapter of the National Building Code — water supply, drainage, gas, solid waste.

IS 1172, IS 1742, IS 2065

Indian standards for water supply demand, building drainage and pumping practice respectively.

CPCB / SPCB norms

Central and State Pollution Control Board requirements for STP/ETP outlet quality, monitoring and discharge.

IGBC / GRIHA water credits

Rainwater harvesting, low-flow fixtures, treated water reuse — sized to actually achieve the credit.

Uniform Plumbing Code (IAPMO India)

Where the project specifies UPC compliance — applied alongside NBC for hybrid project scopes.

WHO / USFDA cGMP

For pharma facilities — purified water systems, WFI generation interface, dead-leg management in plumbing.

Where this scope is typically deployed

Sectors we deliver plumbing EPC for.

The plumbing brief looks similar across sectors on paper, but in practice the rainfall intensity, hot water demand profile, and effluent treatment requirement differ significantly. We engineer for the specific site, not the spec template.
