Drain time: update on corrugated pipe


Innovations in corrugated pipe include an inline inspection system, a new model to produce larger pipe and an underground drainage and heating system for a sports stadium


Corrugated pipe is used in a wide variety of applications – ranging from small domestic projects up to large culverts and, sometimes, a unique project. For instance, the University of Alabama’s


Crimson Tide stadium recently received an upgrade that allows grass to grow on it in cooler months. This was needed because the pitch is often used for play-off games in the winter. An underground SubAir drainage system – using twin-wall pipe from Prinsco – was used to achieve this. As well as performing drainage, it provides heat to support grass growth until later in the year. “The SubAir system will have forced heat and


suction, so is a unique project,” said Brandon Wilson, project manager at Precision Turf.

The project used hundreds of feet of perforated and non-perforated high-density polyethylene (HDPE) Goldflo dual-wall pipe from Prinsco. The drainage division of the Plastic Pipe Institute (PPI) named it among the projects of the year at its recent awards. The underground system includes 30in, 24in and 6in pipe. “The 30-inch pipe is taking the bulk of the water and pushing air volume into the field,” said Wilson. “There’s a pretty dense drainage layer there, but the system will handle any amount of rainfall. You’ll never see a drop of water on the surface.” The project also needed a watertight, sealed coupling system, which Prinsco provided – and this included some custom fittings.
