Gravity flow water supply system pdf. Pipeline design 5 summary of suggested design guidelines 19 l 1 3 6 11 2 5 10 18 appendices a. 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.

In this module a first section chapter ii is devoted to the functioning of gravity fed system giving definitions of concept such as gravity pressure and head loss. The following are a list of design parameters that are important in the design of gravity flow water systems. The typical layout of a gravity fed water system figure 1 1 includes a water source transmission main reservoir and distribution system. Not applicable in plain or flat terrain where an elevation source of water supply is not available.

Disadvantages of the gravity method. Maximum pressure limits. Every component between the water source and the reservoir will. General system design and design parameters i t.

It can be downloaded as a pdf. This paper will cover every aspect of the design and construction of a water supply system utilizing potential energy gravity for delivery. Chapter 2 presents a basic understanding of hydraulic fundamentals needed to accomplish water supply testing and evaluation accurately and chapter 3 presents water supply system evaluation methods for determining existing water. In order to size a gravity fed system it is important and necessary that a technician knows and understands how gravity fed systems work.
