The FloPlast Land Drainage system is used to remove excess water from fields and gardens, or any area where excessive water is a problem. The perforations allow seeping water to ingress the pipe, capillary action then maintains the water within the pipe allowing it to flow to its destination i.e. Stormwater Attenuation Tanks, also known as Modular Plastic Geo Cellular Units (egg crates) or a watercourse (stream, lake etc.).
