1 introduction
The supplying system of water is mainly classified in 2 types that are the up-feed system and the down-feed system.
The performed by pumping water from the bottom storage tank.
The pressure of pumping will supply water to the units at any floors of the building.
this system has no storage tank on the top of the building which is suitable for a building that is not too high.
on the other hand, the down-feed system has the storage tank on the top of the building.
It is performed by pumping the water from the bottom storage tank to be kept in the top storage tank, and then water will be discharged to the units on various floors of the building.
the water flow is enhanced by the gravity force.
the advantage of down-feed system is a lack of energy loss for supplying water at any floors.
