The water pressure of the water supply pipe network is stable and does not change with the change of water consumption, which improves the quality of water supply;

It avoids the phenomenon of running water and water leakage caused by the abnormal increase of water pressure in the water supply pipe network, and reduces the maintenance cost;

The energy-saving effect is remarkable, and the increased investment in the constant pressure water supply system can be fully recovered in more than one year;

The waste of water resources is avoided, and the further expansion of the funnel area of water level drop formed by excessive exploitation of groundwater is prevented.
