There are so many uses for PTI high-density polyethylene corrugated drainage pipe and fittings in this category of applications that we would need several more pages just to begin. Suffice to say, that these applications are growing faster than we can print. Almost daily, our company is asked how well our products resist chemicals, abrasive wear, sunlight and a host of others. We often refer them to the Corrugated Plastic Piping Association of North America or a major chemical company for the answers they need to properly design their project. Our single-wall products are used in the parks and recreational areas for everything from sand-filled shapes for children's play, to serious water-handling solutions to keep ball fields and soccer fields dry and playable. Golf courses use more sub-surface drainage now than ever before. Water belongs in the hazards, not in the fairways or the sand traps. Good sub-surface drainage systems keep the fairways fair, the greens green and the sand traps sandy. PTI provides both single and double walled corrugated pipes for the recreational environments. For some examples, see the pictures below of an exclusive Golf & Country Club in the Orlando, Florida area.
