Approved Alternative Effluent Disposal Systems
Approved Alternative Effluent Disposal Systems
Aerobic Treatment Units
Aerobic Treatment Units (ATUs) are small (‘package’) wastewater treatment plants. Due to the treatment and disinfection process, the effluent from several systems may be used for garden irrigation. Some ATUs are also approved for Phosphorus removal. The listed systems have standard approval as domestic models (they may also be used in commercial situations). They are to be installed and operated in accordance with the Health (Treatment of Sewage and Disposal of Effluent and Liquid Waste) Regulations 1974 and the Code of Practice for the Design, Manufacture, Installation and Operation of Aerobic Treatment Units (ATUs) Serving Single Dwellings.
As the conditions of approval can vary between designs, persons interested in installing a particular ATU should confirm it meets their needs and discuss site requirements with the local government.
ATUs have regular service requirements and maintenance must be through an Authorised person or their staff/subcontractors.
More detailed information on ATUs is contained in the Aerobic Treatment Units pamphlet and the Code of Practice.
