The length of the capturing canal is made as 1.5-2.5 times more than the width of the contaminated area. The capturing canal and the water facility are connected by a discharge canal. The discharge canal is equipped with a water outlet and a semi-submerged shield. The lower slope of the banked capturing canal is equipped with an anti-filtration screen. The banked part of the capturing canal is sown with oil-tolerant perennial herbs. The discharge canal water area is sown with surface water plants - water hyacinth Eichhornia.
