Municipal administration delivery pipe supplies water to low level tank, by low level tank automatic regulation, and the guarantee that supplies water is good: the low-level water tank replenishes water during the low peak of water supply, and the water tank is shut down to feed water during the high peak. When water is supplied to the high-level water tank, the water tank water supply pump operates at rated power frequency, which is the highest efficiency point of the water pump, and is efficient and energy-saving; the water tank stops running after being filled, and because the water tank has certain volume, the interval time of the water supply pump set of the water tank between running and stopping is longer, the problem of frequent starting does not exist, and compared with frequency conversion running, the energy consumption is lowest, and the equipment is not easy to damage. The water supply to the lower layer user is carried out by the high-level water tank, the pressure is not enough due to the fact that the fall is small for the top layer district user of three to five layers close to the high-level water tank, the high-level booster pump can be used for pressurizing and supplying water, the potential energy of the middle zone user which faces downwards can completely meet the water supply pressure through the high-level water tank, the energy consumption is zero, meanwhile, the high-level booster pump can be used for supplying water for the cleaning device, and the full utilization of the equipment is.
