This Australian Technical Specification sets out requirements and a design methodology for inline sewer dosing units (SDUs) and the minimum requirements for the connection within the sewer line. These products are intended to temporarily store and batch wise deliver measured volumes of waste water to the sewer line.

This Australian Technical Specification sets out requirements and a design methodology for inline sewer dosing units (SDUs) and the minimum requirements for the connection within the sewer line. These products are intended to temporarily store and batch wise deliver measured volumes of waste water to the sewer line.The basis for both the use of the unit and the design methodology is to supplement reduced water closet (WC) water usage with water from other plumbing fixtures to provide volumes that are similar to the historical design volumes for WCs.The SDU allows reduced water usage throughout the dwelling while at the same time maintaining sufficient transport volume as to match the original design intent of the sewer line system.An SDU is used to allow for the delivery of a minimum dosage of waste from the water closet and wastewater carrying medium from throughout the dwelling.The minimum dosage allows for the application of all water saving devices throughout the dwelling while at the same time ensuring that wastes from the water closet have sufficient carry medium.The application of an SDU ensures that the sewer line does not receive less than a minimum measured dose. This has positive implications to the design charts and minimum grades as noted in AS/NZS 3500.2 and AS/NZS 3500.5.The SDU also has applications as - - a greywater and blackwater mixing device prior to the transport stage through the sewer line to the sewer main; and- a greywater dosing system for re-use systems to ensure volumetric carry distance and dosage volume consistency.
