Maximum pressure limits.
Gravity flow water supply system.
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.

If power is a problem gravity may be your best bet for a reliable water supply.
Long before there were complicated electric pump systems for rural properties there was gravity.
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.

No pump is required.
The following are a list of design parameters that are important in the design of gravity flow water systems.
The slope of the incline which determines how fast and how easy the water flows.
In gravity flow water systems the velocity is very low and the velocity component can be ignored.
The type of the terrain.
And today in many parts of new zealand where access to power is uneconomic or impossible gravity fed water systems are still used to keep water flowing to troughs and homes.
It sounds like such a simple theory too.
