Gravity Water Supply System

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.

Gravity water supply 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. Source intake sediment removal and storage. As the name suggests a gravity fed system relies on gravity to help water flow through your home s pipes. So it is called the dual system.

It is a combination of a gravity system and pumping system. The mains supply of water enters your property and divides into two pipes. One way dual system. 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.

These deaign notes primarily coyer simple gravity flow water systems. In this system water is pumped to the elevated reservoir and then supplied to the consumers by the action of gravity. Gravity fed water systems require the following. 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.

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. Source the source can be any supply of free water. The distribution network is connected with elevated reservoir but not with direct distribution pumps as shown in the figure above.
