Pitch Drainage Pipe System

The Pitch Drainage Pipe System is an infrastructure solution comprising perforated pipework, filter aggregate, geotextile and fittings, designed to collect water entering the sub-base of artificial-turf fields and outdoor sports areas and convey it to a controlled outlet. Pipe diameter and perforation, line spacing, installation level and gradient, collector connections, inspection and cleaning access, outlet capacity and surcharge risk are calculated from rainfall data, soil permeability and field geometry. The illustrated build-up is representative and is not a standard trench detail for every project. Pipe class, bedding and surround material, geotextile use and discharge point are defined by the approved drainage design.
