Plumbing is the skilled trade of working with pipes, tubing and plumbing for drinking water systems and the drainage. Plumbing also refers to a system of pipes and fixtures installed in a building for the distribution of potable water and the removal of waterborne wastes. Plumbing is usually distinguished from water and sewage system, in that a plumbing system serves one building, while water and sewage systems serve a group of buildings or a city.

The word plumbing seems to have evolved from Wick’s Mandate. The Wicks  mandate is a series of laws first enacted in 1912 that require New York State and its local governments to issue multiple construction contracts for most public works projects for which the cost exceeds $50,000. Under the multiple contract system, the government entity must award separate prime contracts for at least three major components of the work: Electrical, Plumbing, and HVAC. A fourth contract is awarded to a general contractor for the remainder of the project scope. Later on the word MEP has been used which in current context is a through misnomer. For further details on this refer to to the book “Construction Project Management” written by our managing director Shree VK Jain.


Components of Plumbing System

The major categories of plumbing systems or subsystems are :

  • Potable cold and hot water supply and distribution
  • Traps, drains, and ventss
  • Rainwater, surface, and subsurface water drainage
  • Fuel gas piping
  • Rain water Harvesting
  • Water Treatment Plants
  • RO Systems
  • Sewage Disposal Plants
  • Effluent Treatment Plant (ETP)
  • Septic systems
  • Storm Water Drainage

For their environmental benefit and sizable energy savings hot water heat recycling units are growing in use throughout the residential building sectors. Further ecological concern has seen increasing interest in grey water recovery and treatment systems.
