This method is much suitable when the source is the river or impounded reservoir at sufficient height than the target community. When the distribution reservoir is located at a higher elevation than the target community then water can be supplied with the gravity flow. The distribution systems can be classified as follows: Therefore, the same pressure in the pipelines is necessary which should force the water to reach every place. Methods of Water Distribution Systemįor efficient distribution, it is required that water should reach every consumer with the required rate of flow. So, it is called an intermittent system.ġ.3. The water flows in the consumer’s tap at certain intervals. If adequate water is not available, the whole community is divided into several zones, and water is supplied in each zone for a fixed time in a day or alternate days. In this system, a sufficient amount of water is always available for consumers to use and also for an emergency like fire fighting.ĭue to the continuous circulation water remains fresh but the losses will be more if there are leakages in the system. This is the best method in which the water is supplied to the community during all 24 hours of the day. There are two types of water supply systems. The distribution layout should be such that it should supply water even during repair and maintenance time. The system should have adequate pressure but the pressure should not be high causing the bursting of pipes and fittings.Ĩ. It should not be laid below the sewer lines as far as possible.ħ. Any type of contamination of water should not occur during the distribution.Ħ. The system should be watertight and leakage should be least as possible.ĥ. It should be able to draw enough water during an emergency like fire fighting.Ĥ. Sufficient water should reach all consumers.ģ. The system should be economical to maintain and operate.Ģ. Requirements of the good water distribution systemġ.
The cost of the distribution system is about 40-70 % of the total of the entire scheme.Ī good water distribution system aims to supply water to all the consumers whenever required in sufficient quantity with required pressure without any leakage.ġ.1. The distribution system includes pumps, reservoirs, valves, water meters, pipe fittings, etc. The process of distributing treated water to the consumers is called a water distribution system.
