2. Rogerson Intake
Water is taken from the Rogerson river above this concrete structure (weir) and flows through to the reservoir (pond)

3. Reservoir
Water flows through to a turbidity meter (shown as valve chamber) that measures the turbidity. If it’s high then the water is discharged back to the river

4. Treatment Plant Overview
Processing
Water enters the plant from the reservoir (pond)
Water is filtered via 4 sand filters
From the filters the water is pumped to the tank farm having been UV treated
The plant is activated via a flow meter shown by the green line
Water is pumped to tank farms and gravity fed to the township
Operations
If turbidity is high then the water is diverted away from the pond
If the turbidity is high and the ponds are low, water is allowed into the ponds and chlorine dosing commences on the water supply to manage any health risk
If power is lost to the plant the generator activates and the sites continues to run as normal
If the generator fails to start the plant is shutdown and water cannot pass through the treatment plant

5. Future Works Improved Communications
Generator Visibility
Control of Pumps and Reservoir Levels
Remote Site Control
Flocculent Treatment – this is a coagulant that combines small particles together to prevent them passing through the sand filters
Chlorine Dosing Management
FAC and Total Chlorine Monitoring
