Combined sanitary drains

A combined sanitary drain is a private sanitary drain which connects two or more properties to one common Queensland Urban Utilities (QUU) sewer connection point. The first property on the combined sanitary drain will usually have the QUU sewer connection with a private drain running through this and neighbouring connected properties.

Am I on a combined sanitary drain?

To find out if you have a combined sanitary drain on your property, contact Council's Plumbing Services on 07 3403 8888. Copies of the sanitary drainage plan for the property and/or adjoining properties may be available for purchase from Council.

Maintenance responsibilities

Combined sanitary drains are not owned by Council or QUU. The ongoing maintenance of a combined sanitary drain is the responsibility of the owners of the properties serviced by the drain. Each owner must ensure that the section of the combined sanitary drain located within the boundaries of their property complies with the requirements of the Plumbing and Drainage Act 2018 s70, and is kept in good condition and operating properly. Any defects that occur in the combined sanitary drain must be rectified by the owner of the property that contains the defective section of a drain.

How do I come off a combined sanitary drain?

Before deciding to come off a combined sanitary drain, the property owner should find out where their property is on the drain. Where there are other upstream properties connected to the drain, the property owner wishing to disconnect may be required to provide a new sewer connection to those properties as well as their own. For further information relating to new sewer connections contact QUU on 13 26 57.
