General Guidelines While Designing Water Supply Pipe Lines

Designing pipe lines in a house or building needs careful vision. There is no cross connection between pipes for drinking water and pipes containing impure and waste water. Pipe work is accessible for inspection, replacement and repair. All joints of pipes are completely water tight.

• Vertical pipes are fixed in such a way that they should be away from window, ventilator and cabinets etc.
• All joints of pipe work should completely be water tight.
• Provision of direct supply of water should be kept in kitchen for drinking and cooking etc.
• No pipes should be laid or fixed to pass above/below or adjoining any sewer line, scour outlet or drain or any man hole.
• Under ground pipe line should be laid at such a depth that it can not be damaged by traffic load etc.
• To reduce friction losses, change in direction and in diameter of pipes should be gradual and not abrupt.
