Water flushing
Flushing is when water is released from a fire hydrant or access point at a high flow rate and is used to clean our water mains. Water is released and tested until it either returns to a clear appearance or the turbidity levels are within the Australian Drinking Water Guidelines.

Stormwater out of sewer - inflow and infiltration testing
Our sewerage network is not designed to manage the inflow and infiltration of stormwater during rainfall. Inflow is where stormwater enters the sewerage network, generally via private plumbing that is incorrectly connected to the sewer.
Infiltration is stormwater entering the sewerage network, generally by seeping through cracked, or unsealed underground infrastructure.
