One of the most basic ways to build a running water system is the gravity fed 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.
The system cost 130 per family and took 30 people 18 days to build.
Maximum pressure limits.
Before the system can be designed the area must be surveyed.
The exercises follow a logical order for designing a distribution system and increase in difficulty.
If this is your first gravity flow water system and you want to begin designing or check if a design will work keep on reading.
