Storm water infiltration is a viable and practical solution to manage storm water runoff when the soil drains well and the water table is low enough. It is cost efficient and an ecological approach. Acting as a natural filter medium it removes contaminants and protects ground water from pollution. After accumulating in a basin (a vegetated depression), the water percolates into the subsoil that acts as a natural filter adding the benefit to reduce water table reductions and soil erosion. Storm water infiltration helps to meet township requirements when impervious surface coverage increased.
