The objective of this Water Industry Standard is to provide design, manufacturing and performance requirements for manufacturers of plastics collection tanks for storage of sewage in pressure and vacuum sewerage systems and which are specifically designed for buried installation. Given that a standard for this product is not available from Standards Australia and other overseas standards organisations, it is likely that further improvements to this initial standard may be necessary as experience is gained with its use. Performance requirements in this Standard have been drawn from AS/NZS 1546.1, AS/NZS 4766, AS 3571.1 (ISO 10467) and other published standards, wherever practicable
