The Standard gives specific details for septic tanks for domestic all-waste, blackwater and greywater; and specific details for land-application and absorption systems, including conventional trenches and beds, evapo-transpiration systems, mounds and irrigation areas. These are regarded as the current most commonly used systems and are used as examples throughout the Standard.
