Gravity Water Supply System

Source the source can be any supply of free water.

Gravity water supply system.

It is a combination of a gravity system and pumping system. An intake that is screened from debris and submerged sufficiently to ensure no air enters the pipeline a properly sized pipe diameter considering the pipeline length the elevation difference the energy available to move water and the water flow required. One way dual system. The distribution network is connected with elevated reservoir but not with direct distribution pumps as shown in the figure above.

Gravity system of water supply is that system in which water flows under gravity without use of any external energy to deliver water from source to tap stand. Of course you may have to deal with some troubleshooting down the road as well. Source intake sediment removal and storage. Gravity water combines rainwater harvesting elevated storage and gravity fed filtration providing schools in developing countries with a source of safe drinking water that is on site self sustaining and 100 energy free.

This is often the only feasible alternative for many rural areas at the present time and in many countries a major portion of the funds available for water systems are allocated to gravity flow systems. There are four basic elements to a gravity water system. In this system water is pumped to the elevated reservoir and then supplied to the consumers by the action of gravity. As the name suggests a gravity fed system relies on gravity to help water flow through your home s pipes.

The mains supply of water enters your property and divides into two pipes. One pipe takes the water to the cold tap in the kitchen and the other passes it to a large water storage tank which is usually stored in the roof space. The gravity flow water supply system is most appropriate for rural sloppy terrain of nepal where the source is usually situated at the uphill and the community is as far down.
