Presby septic systems have been tested and proven to be more effective at treating unhealthy effluent contaminants than other leaching systems. Since groundwater is the source of many households' drinking water, eliminating these unhealthy contaminants is crucial. The Presby system includes Enviro-Septic leaching pipe and Presby Maze septic tank inserts. We are proud to be a preferred supplier of Presby Environmental. Click on one of the many Presby links located on this page for additional information on all their pipe products. If you prefer, come to our store and ask for a Presby pipe specialist.

We feature a variety of Hancor wetland structures and pipe systems. We stock Hancor Smoothwall pipe in 10' (3m) lengths and 4" diameter. Hancor pipe fastens with a simple, secure bell-and-spigot connection. It is made with a white, high density polyethylene layer around a black polyethylene core to form a lightweight pipe with excellent stiffness. Smoothwall is very popular for sanitary leach field use because of its low cost, large perforations, and high strength. Because Smoothwall pipe is relatively stiff in the longitudinal direction, it can easily be laid straight and "true to line and grade". Smoothwall pipe requires a stone backfill envelope to allow it to function effectively for leach field applications.
The Hancor pipe provides for safe, easy, efficient installations without breaking, splitting or cracking, and is more impact-resistant that PVC, ABS or styrene.
Smoothwall pipe can be used for all your turf drainage needs as well as sidewalk culverts and on-site waste management systems.
Polylok has combined the best features of concrete and plastic risers to create their patented riser system. These stackable risers hold their shape, screw together, and are both water resistant and air tight. Structural ribs located inside prevent frost from adhering to the riser in frost prone areas. Polylok covers give you easy access to any depth tank regardless of the season.
