A sub-drain is an underground drainage system installed beneath roads, pavements, or landscaped areas to collect and remove excess groundwater or subsurface water. It typically consists of perforated pipes surrounded by gravel or filter material, allowing water to enter the pipe while preventing soil intrusion. Sub-drains help reduce hydrostatic pressure, prevent soil saturation, protect infrastructure from water-related damage, and direct collected water to storm sewers or natural drainage channels. |
