For any aboveground system to operate correctly, a pressure distribution system is required. Any such system has four interdependent components: a pump tank and pump, pump controls, pipes that deliver
effluent, and orifices that discharge effluent into the treatment area.For many years the pump made pressure distribution systems alternative or advanced technologies. Now, pressure distribution is used in subsurface trenches and beds, aboveground systems, and advanced media filter systems. Because the use of all these systems is increasing, installers need to understand where to apply pressure distribution, how the components work together, and the keys to installing the systems properly.
