Onsite Sewage Management and Greywater Use
In this section you will find general information on the septic safe programme, connection to sewer, types of systems, grey water usage, pollution, and the protection of groundwater.
In 1999 poorly managed septic systems were identified as being a major contributing factor in several cases of hepatitis, and food poisoning. Additionally, leaking septic effluent can contaminate groundwater supplies, soils and vegetation, as well as surface waters potentially leading to recreational areas such as rivers, creeks, dams and other swimming holes. Badly managed septics can cause human health and environmental hazards up to 50kms downstream of the system.
This hazard identification spurred the launch of the 'Septic Safe Programme', for which Council is the regulator.
The installation and operation of on-site sewage management systems in the unsewered areas of the City is a major function performed by Council's Sustainability and Better Living Division and involves the assessment and approval of new and existing septic tanks, aerobic treatment plants, composting toilets and cesspits.
For any property owners or occupants operating or using an on site waste water management system, the Department of Local Governments 'Septic Safe Guide' should be read, and may be downloaded below.
Users and operators of Sewage Management Facilities should ensure that their household water usage is moderated and stringently monitored to prevent overloading the system pre-maturely. Additionally, chemical agents such as bleaches / ammonias should be avoided, and household cleaning products low in sodium and phosphorus should be selected for use.
Remember - when it comes to operation of an on site waste water management system, one ounce of prevention is equal to one tonne of cure.
Greywater
Greywater is the wastewater generated from your washing machine, shower, bath and basins which, when used safely, can replace drinking water for watering lawns and gardens. Water from your kitchen can also be reused as greywater if the correct treatment process is put in place. The NSW Government has also published a great website
greywater reuse for households and five easy to follow
fact sheets.
