Pipeline
The layout of the pipe lines should be as for as possible straight line. There should not be many bends in the pipe lines, which greatly reduces the discharge due to internal turbulence in the pipes. The metal pipes need to be protected with a coating of anti corrosive paint. Pipe lines passing through dams and marshy lands to be protected by canvas soaked in bituminous materials. The pipe line should be rest on at least 10 cm thick cement concrete bed with proper side packing on soft soil to safe guard against settlement. The diameter of the pipe should be large enough to discharge the required volume of water in specific time. The mouth of the supply inlet should be covered to prevent the entry of trash fish or predatory.
