The work includes, but is not limited to: 

• Smoke testing of: 
  • Property storm and sewer connection to Council sewer infrastructure 
  • Storm infrastructure and interconnection between storm and sewer infrastructure of Council 
• Infiltration into sewer collection system including: 
  • Investigation of sewer infrastructure failures 
  • Inspections at properties for plumbing compliance 
  • Dye testing for confirmation of significant inflow points. 

Inspections will be performed by: 

• Introducing non-toxic smoke into the sanitary sewer pipes using a high-capacity blower  
• Observing smoke exiting vent stacks at defect locations and documenting defects 

What to expect  
Each individual smoke test will last only long enough to identify the points of smoke exfiltration (less than one hour).  

Smoke is non-toxic. It may be visible at residences which could be an indicator of faulty plumbing. 

The smoke does not cause harm to people, animals or the environment. 

Authorised government officers will require entry to each property to perform external plumbing inspections and potentially identify any points of smoke exfiltration. 

Contact Council on 4970 0700 if special arrangements are required due to animals and/or locked gates.
