Leach Tubing

For leachfield applications, Haviland offers tubing with a 5/8" diameter perforation.  This large amount of inlet area provides greater drainage than conventional slots.  To prevent soil infiltration, a deep understanding of soil types is imperative prior to use.  Check health department regulations for permissible use of this product in your area.  Tubing with 1/2" diameter is available for special applications.

Sock Tubing

Sock tubing is a combination of heavy-duty pipe and a polyester filter wrap.  Primarily used in sandy soils, filter sock ranges in weight from 2.5 to 3.9 ox/yd².  Sock wrap is typically purchased pre-wrapped but is also available separately.
