Storm Drainage

Storm drains are drainage systems engineered to redirect excess rain or surface water from impermeable surfaces like roofs, pavements, and roads through underground pipes into rivers or streams. Storm drainage construction involves installing new underground pipes or below-grade ditches/swales to prevent flooding and erosion by channelling excess water away. The construction process encompasses site preparation, excavation, pipe laying, and backfilling. Local authorities regulate the construction of storm drainage systems, ensuring compliance with building codes and regulations.
