To reduce the risk of toxic substances ingression into the soil, ground and surface waters, it is proposed to protect the bed and slope ramps of the earth embankment for sludge collectors (sediment tanks) with reliable waterproofing – soil-concrete. It has been recommended to perform the screen soil compacted layers inclined towards the tail bay at an angle to the structure base surface, what is more, the angle value is determined by the permissible values of filtration flow’s parameters. The proposed technical solution allows increase the reliability of sludge collectors, as well as minimize the risk of an emergency situation as a result of the ingression of toxic effluents into the soil and water.
