Water tanks

Tank Construction
Tank Construction
Water storage is an important issue for a permanent water supply - especially in regions with non-permanent availability of water. That's why people often think that tanks with a high storage capacity are the best solution. But it is not true, because old or stagnant water may pose a health risk. In fact, it is much more important to build an intelligent tank design and an intelligent water supply structure. Learn more about it in this chapter.

Water piping systems

Integrating a tank in a gravity feed water piping system
Integrating a tank in a gravity feed water piping system
In most cases, the location of a water source is different from the point of consumption. Thus, water distribution through pipes is needed. If the water source is at a higher elevation than the consumption point, you can use gravity for transportation. Otherwise it is necessary to include pumps as part of the piping system.

Piping systems are quite expensive and require community mobilization to implement and maintain. However, it is possible to build a water piping system with only a few technical requirements. Learn more about it in this chapter.
