The polymer pressure composite tower serves to adjust uniformity of water disposal, water consumption, preservation of reserve and fire-fighting water reserves, to supply small enterprises and agricultural facilities. The principle of operation is based on the Act of Communicating Vessels, which is one of the basic laws of hydrostatics. A constant water column height drop is required for maintaining a constant pressure in the pipes. At the same time, water from the tower tank should be distributed through the pipeline to consumers, which means that it should be above the highest point of the water intake.
