The calculation of the tank pumping system requires two previous steps; of the calculation of the daily allocation (and pumping flow) and of the total dynamic pumping load. however, the coordination of some parameters is necessary; which are ex dwg
This system consists, for example, of an elevated tank on the roof of the building; with a height that allows the water pressure established according to the regulations on the most unfavorable piece. from the elevated tank a vertical pipe is lowered from which it will emerge for each floor; a branch to the corresponding apartments; thus giving the supply by gravity. this system requires the study of the pressures of each floor; making sure with this that they do not exceed the appropriate values. in the lower part of the building there is a tank; he can be superficial; semi-underground or underground and in which the water that comes from the public supply will be stored. from this tank a set number of pumps (almost always one or two) connected in parallel will drive the water to the elevated tank.
