Gravity Based Water Supply System

The theory of water system design is extensively covered in other publications.

Gravity based water supply system.

These design notes present simple examples and explanations to illustrate some of the basic principles of gravity flow systems. Each household contributes rs 10 per month for the upkeep of the system. Though the gravity based water supply system is a low cost implementation and low on maintenance funds required for its maintenance are raised by formation of a corpus village development fund vdf. A water and sanitation committee is formed from among the beneficiaries.

Geo politically the project area was always neglected till the exploitation started in 1980s. Disadvantages of the gravity method. Not applicable in plain or flat terrain where an elevation source of water supply is not available. The project focused on creation of gravity based water supply systems gbwss using natural springs and providing water to the tribal villages through pipelines.

Community water plus a research project has investigated twenty case studies of successful community managed rural water supply programmes across 17 states in india. Suggested guidelines for design parameters are also presented. Gravity flow water distribution systems are reliable and cost effective over pumping systems as no external power is required to maintain the flow. Water loss by leakage is comparatively higher as the system remains under constant pressure.

Generally the gravitational networks are designed as branched systems and in order to maintain their looped configuration the missing links are joined by pipes of nominal diameters. Gravity based water supply system in sikkim. Through these case studies the research has gained insight into the type and amount of support to community organisations that is. Of water system 1 2.
