  INTRODUCTION A water pipeis any pipe or tube designed to transport treated drinking water to consumers. The varieties include large diameter main pipes, which supply entire towns, smaller branch lines that supply a street or group of buildings, or small diameter pipes located within individual buildings. Materials commonly used to construct water pipes include cast iron, polyvinyl chloride (PVC), copper, steel or concrete.

  TYPES OF PIPES •Steel Pipes • Galvanised pipes or iron Pipes • Cast Iron Pipes • Concrete Pipes • PVC Pipes
• 5.
  STEEL PIPE • Steelpipes are comparatively expensive, but they are the strongest and most durable of all water supply pipes • They can withstand high water pressure, come in convenient (longer) lengths than most other pipes and thus incur lower installation/transportation costs.
• 6.
  GALVANISED PIPE • Usedseveral years ago. • Less frequent used now as rust can build up inside small diameter pipes. • Can be used to transport grey water. • Use for high temperature or pressure manufacturing processes.
• 7.
  CAST IRON PIPE •Cast iron pipes are quite stable and well suited for high water pressure. • However, cast iron pipes are heavy, which makes them unsuitable for inaccessible places due to transportation problems. • In addition, due to their weight they generally come in short lengths increasing costs for layout and jointing.
• 8.
  CONCRETE PIPES • Concretecement pipes are expensive but non-corrosive by nature. • Their advantage is that they are extremely strong and durable. • However, being bulky and heavy, they are harder and more costly to handle, install and transport

  PVC PIPE • PVCfull name is Poly Vinyl Chloride. • Used for hot and cold potable water as well with sewage application. • Vary on their thickness and configuration depending on the application where to be used. • Example : pressure water pipes are not the same as sewer pipes and not the same as the ones used on storm drainage systems.
