Can I appoint you as a plumbing (PHE) consultant only?
Yes. As a plumbing and public-health consultant we take the design alone: water demand and storage, pump sizing, drainage and vent layouts, STP and rainwater sizing, and the BOQ. Execution is quoted separately.
Do you design STP and rainwater harvesting for approvals?
Yes. We design sewage treatment plants (STP), rainwater harvesting and water-supply systems sized to pollution-board and local-authority norms, and obtain the relevant consents so your building is compliant.
What plumbing scope do you cover?
Domestic and flushing water supply, drainage and sewage, hot-water systems, pumps, water treatment, STP and rainwater harvesting — designed, installed, tested and commissioned end to end.
How do you size water tanks and pumps?
We size storage and pumps from occupancy, fixture units and demand per NBC 2016 and IS 1172. Our free water-demand and pump-head calculators give a quick estimate; the final design is engineered for your building.
What is a PHE shaft?
A PHE shaft is the vertical service duct that carries a building's plumbing risers — water-supply lines, soil and waste stacks, vent pipes and rainwater downtakes — from floor to floor, with access panels at each level for inspection and maintenance. It is planned per NBC 2016 Part 9 alongside the architectural layout.
How big should a PHE shaft be?
Shaft size follows the pipes, not a rule of thumb: it is worked out from the number and diameters of risers it carries, their clamping arrangement, insulation where applicable, and the clear access needed to reach every joint. The classic failure is a shaft fixed at architecture stage before the plumbing design exists — we coordinate shaft sizing during design so risers never end up buried or unreachable.
What does PHE stand for in plumbing and MEP?
Public Health Engineering: the water and waste side of a building. It covers domestic water supply and storage, pumping, drainage and sewage, rainwater disposal and harvesting, and treatment (STP/WTP). On MEP drawings the PHE package is the plumbing scope, kept separate from fire-fighting even though both run on pipes and pumps.
What is a PHE pump room?
The plant room for the building's domestic water pumps: transfer pumps from the underground tank, booster or hydro-pneumatic sets that hold pressure on the upper floors, and often filtration and softening. It is kept separate from the fire pump room, which houses the fire-fighting pumps. We size it from the water demand and pump head, then lay it out for maintenance access, floor drainage and noise.
