The present invention provides a leveling differential-pressure diversion peak-shaving water tank with a function of preventing stagnant water and stale water, which comprises a water storage and distribution tank, a water inlet pipeline, a water outlet pipeline and a front tank. The water inlet pipeline is arranged at the upper portion of the water storage and distribution tank and used for feeding water into the water storage and distribution tank. The water outlet pipeline is arranged at the lower portion of the water storage and distribution tank and comprises a main water outlet pipe and a plurality of water outlet branch pipes. One end of each water outlet branch pipe is connected with the main water outlet pipe. The front tank comprises a front tank water box, a front tank water inlet pipeline and a front tank water outlet pipeline. The present invention further provides a water supply pumping station.
