First: town sewer or on-site system?

Gatton has a town sewerage network. Urban Utilities operates the Gatton Sewage Treatment Plant (Queensland WetlandInfo (opens in a new tab)) and is the water and sewerage provider for the Lockyer Valley (Urban Utilities – our geographic area (opens in a new tab)). Whether your lot can connect depends on where the sewer network runs. Before you plan an on-site system, confirm with Urban Utilities whether sewer is available to your lot. If it isn't, you'll need an approved on-site sewerage facility.

Council is local

On-site sewerage permits in the Lockyer Valley are assessed by Lockyer Valley Regional Council's plumbing team, at 26 Railway Street, Gatton (phone 1300 005 872) (council plumbing and drainage (opens in a new tab)). Your plumber normally lodges the application, but you can call council's plumbing team to ask about your property's records, including any existing approved system.

Check flood information before you place a disposal area

Parts of the Lockyer Valley floodplain are flood-prone. Council runs a free online Flood Information Portal: select your lot and points within it, and it emails a report with flood depth, velocity and hazard information for those points (Queensland Reconstruction Authority case study (opens in a new tab); council announcement (opens in a new tab)). It's worth running a report for the spot where a tank or land application area might go and sharing it with your designer.

Once a land application area is approved, don't move or change it without approval. Councils approve its location, and setbacks apply from buildings, boundaries and water sources (QBCC guide (opens in a new tab)).
