On-Site Sewerage Facilities

A Household Sewerage Treatment Plan (HSTP) and a Septic System are on-site sewerage facilities.  On-site sewerage facilities are facilities installed on the premises for the treatment of sewerage generated on the premises.  The resulting effluent is disposed of on the premises by either surface spray irrigation or by subsurface disposal or off the premises by a common effluent drainage system.  The on-site sewerage facility may also store sewerage generated on premises for disposal off the premises by a licensed contactor.

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 Household Sewerage Treatment Plans are required to be serviced annually or as required by the model approval.

A licensed service person must give Council a report on the condition of the facility within one month after servicing the facility.

For new applications a site and soil assessment is needed to determine which type of on-site sewerage facility and effluent disposal system is appropriate for your premises.

The operation of On-Site Sewerage facilities is governed by Logan City Council's, Local Law No 13 and subordinate Local Law 13.1 (On-Site Sewerage Facilities Operation and Serving) 2012 gazetted 23 November 2012.
