Disposing of on-site effluent must comply with the Health (Treatment of Sewage and Disposal of Effluent and Liquid Wastes) Regulations 1974. Depending on the site location and conditions, disposal may be done via a conventional septic tank system or through an Aerobic Treatment Unit.
Where septic tanks are to be de-commissioned or removed the work must comply with regulations 20 and 21.
Mechanical equipment wash down bays that discharge waste water on site (ie no sewer connection available) are required to be approved by the City's Environmental Health Services. Please refer to the application form and associated information note for further guidance regarding this process. Information can also be obtained by contacting Environmental Health Services on 9792 7100.
It is well known that asbestos fibres that are not bound together with cement can cause health problems in humans. But when these fibres are not disturbed they are unlikely to be hazardous.
Fibres only become volatile when they are airborne and are inhaled. Individual fibers are generally not visible to the naked eye and must be small enough to overcome the body’s natural defence mechanisms and penetrate into the small air passages of the lungs.
Power tools can disturb fibres when they are used during cutting, drilling, grinding or sawing operations. A hazard may exist for people directly involved in such activities and precautions such as wearing a suitable mask or breathing apparatus should be used. Surface weathering of asbestos cement products may also lead to fibers being released, but the risk to humans from fibres being exposed in the environment is negligible.
