Water pressure in pipes changes by water use. Water is used less by night than by day, so water pressure is higher. The change in water pressure, without proper resolution, may break the pipes, cause local redundancy or shortage of water and increase costs. In the past, to harmonize water pressure, high water towers were built. When water is redundant, pipe pressure is increased, so water is pumped into the tower. When water in the pipes is weak, water from the tower will be pushed back to the pipes to even pressure. With inverters, water can be poured into pipes enough for use. Water demand can be set by daytime and nighttime levels and the control system will make corresponding changes in the volumes of raw and treated water in the supply system. Water use can also be set automatically: the system operates by water demand, making changes in the water pressure in the pipes and impacting the control system to keep water pressure stable at a required level. This technology helps save energy by 30-35%, reduce production costs, avoid damage risk when turning on/off the pumps and valves as before.
