On-Site Sewerage Facilities
Domestic treatment plants are facilities installed on premises for treating sewage generated on the premises. The resulting effluent is disposed of either on or off the premises by common effluent drainage or collection from a tank located on the premises. The on-site facility may also store sewage generated on the premises for its subsequent disposal off the premises by collection. A domestic treatment plant is an on-site sewerage facility.
A person must not install, change or take away an on-site sewerage facility without the approval of Council.
The owner of an on-site sewerage facility must take all reasonable steps to keep the facility in good working order. Standard domestic treatment plants are required to be serviced every three months. Sand filter facilities are required to be serviced annually.
The service person must give the Council a report on the condition of the facility within one month after servicing the facility.
A site and soil assessment is needed to determine which type of on-site sewerage facility is appropriate for your premise.

Sewer access chambers
A sewer access chamber is a below ground level structure, with a cover, built in the line of a sewer or sanitary drain, through which a person, authorised by Council, may enter the sewer or drain.
A person must not without the approval of Council place any material or change the surface of land in a way causing ponding of water over a sewer access chamber.
