A soakaway (or infiltration trench) is a subsurface structure designed to disperse stormwater or treated effluent into the surrounding soil, thereby reducing surface runoff and recharging groundwater. When a soakaway becomes blocked, its infiltration capacity drops drastically, leading to surface flooding, structural damage, and environmental hazards. This paper examines the primary causes of soakaway blockage—namely sedimentation, biological clogging, and inappropriate waste disposal—and outlines diagnostic techniques and remedial strategies.
