IMPROVEMENTS IN SOIL ABSORPTION TRENCH DESIGN

An unique modification of the soil absorption system is the capillary seepage trench (CST). The CST has an impermeable liner at the bottom of the trench and partially up the sidewalls, which prevents direct percolation. An exploratory experiment has been conducted to investigate the effect of the impermeable liner on the removal performance of soluble organic matter. The findings of this preliminary experiment are presented here. The results show that the CST may be a viable alternative to the conventinal soil absorption system. Removal of organic matter was significantly better in the CST than in the conventional system. Conclusions drawn from the study are discussed.
