Lockyer and Mid Brisbane River integrated sensor network for source water monitoring of a drinking water treatment plant

The source water for one of SEQWater’s drinking water treatment plants shows large variations in turbidity and organic loads as well as hardness and salinity, related to high- or low-flow conditions. The ability of the treatment plant to continue and manage supply through this high salinity or high turbidity events is partially reliant on the early detection of poor water quality issues in the river, and the subsequently increased dilution of poorer quality water with higher quality water.

Significant savings could have been made if a more robust and resilient installation design had been selected at the start of the project.
