Pumping, Storage,

and Dual Water Systems

8.1 PUMPS AND PUMPING STATIONS
Pumps and pumping stations (Figs. 8.1 and 8.2) serve the following purposes in water
systems:
1. Lifting water from its source (surface or ground), either immediately to the com-
munity through high-lift installations, or by low-lift systems to purification works
2. Boosting water from low-service to high-service areas, to separate fire supplies,
and to the upper floors of many-storied buildings
3. Transporting water through treatment works, backwashing filters, draining compo-
nent settling tanks, and other treatment units; withdrawing deposited solids; and
supplying water (especially pressure water) to operating equipment.
