AFS Distribution Valve Basins are designed to house the Orenco Systems distribution valve for zoned on-site wastewater dispersal. The distribution valve allows splitting large systems into manageable zones which can be dosed with smaller, more efficient pumps. The Distribution Valve Basin includes either a 24" or 30" PVC basin with a sealed bottom and fiberglass lid.
