Description: More than 40 million meters of subsurface drains are installed each year in Canada. Studies such as those by April (1967), and Irwin and Ayers (1970) indicate that the drainage improvements needed on land currently being farmed will require installations of approximately 40 million m/yr for another 80 yr. Considering the vast requirements in material, energy and money for the production and installation of these billions of meters of subsurface drains, the need is apparent to refine design and installation techniques to reduce the consumption of material and energy as well as money costs per meter of drain tube installed. Prior to 1974, the smallest drain tile or plastic tube in common use in Canada was 100 mm inside diameter (i.d.). Probably less than 20% of the 100-mm drains installed are ever utilized at their maximum hydraulic capacity. One hundred-mm tile became the accepted minimum lateral drain diameter some years ago because of some of the following factors:
