1. Council area: rules may vary between councils.
2. The number of bedrooms is the way in which the number of people occupying any residence is calculated by the AS/NZS Standard ‘On-site Wastewater Treatment’. Volume of water to be treated is calculated by the number of potential occupants. Most councils and the AS/NZS Standard also count any other rooms that could be used as bedrooms such as media rooms, libraries or even sunrooms.
3. The water source you have determines the volume of water each person is likely to use. If you have a bore or a reticulated supply the volume will be more than if you have supply from a rainwater storage tank.
4. Most new homes now customarily install standard water reduction fixtures which include dual flush toilets, shower flow restrictors, aerator taps and water-conserving washing machines. These fittings use less water so the use per person goes down and this reduces the size of your AES treatment system.
5. What is the type of soil underground say 1 metre deep in the area where you could construct an AES treatment bed? Loam is usually dark-coloured, organic-rich soil but unlikely to be 1 metre deep, clay soils are those that stick to your shoes or boots and do not allow water to drain away quickly after rain.
