PVC Drain Basin

PVC Drain Basins are used as a junction box when drainage system inlets or outlets change diameter, change pipe type, change elevation or change direction. Drain basins allow for multiple inlets or outlets in one structure and for a water inlet and sediment collection point entering a drainage system.
