The GeoMat leaching system from Geomatrix Systems consists of a core of fused, entangled plastic filaments surrounded by a high-capillary geotextile fabric. When sized accordingly, it is compatible with pretreated wastewater or septic tank effluent. Uses also include subsurface irrigation and evapotranspiration systems. It is 1 inch high and available in 6-, 12- and 39-inch widths. A pressurized distribution pipe typically runs the length of the lateral for uniform application of wastewater. Additionally, it can be configured with a time-dose pump station for flow equalization. The combination of pressure dosing and flow equalization reduces peak hydraulic loading. The thin, narrow profile, shallow burial depth and uniform hydraulic loading maximize efficiency of oxygen transfer. It has complete surface contact with the soil and is not reliant on complex valving and filtration systems. The distal head pressure is fully adjustable through manual zone valves. 888/764-5247; www.geomatrixsystems.com.
