Challenge the client faced:
The Lilly Road Tank has the capacity to hold 15ML of potable water, and supplies water to Margaret River and surrounding schemes in the south-west region of Western Australia.
Due to the scheme usage, fluctuations in flows from the tank meant that inconstant chlorine residual readings were occurring within the tank holdings across the day.
Solution provided:
The Water Corporation engaged WestWater to design, manufacture and install a free-standing Chlorine Analyser cabinet, including sample feed and sample return lines.
Sample water is taken from the outlet of the Lilly Road tank and fed through the new Chlorine Analyser, to continuously monitor chlorine residual levels in the tank.
WestWater also completed the integration of this new Chlorine Analyser cabinet into the existing site control and SCADA system.
Conclusion / project outcome:
Prior to the Chlorine Analyser cabinet being installed, operational intervention was required twice daily to monitor and adjust chlorine dosage levels accordingly to maintain safe chlorine residuals within the tank.
This was a drain on the limited resourcing capacity of the region and posed the risk of causing water quality compliance issues.
The new Chlorine Analyser cabinet has been installed on the outlet of the tank, and continuously monitors the chlorine residual levels of the water in the tank.
Integration with the existing site control and SCADA system also provides local operators with remote access to this data.
