Plover Cove Reservoir is the biggest freshwater lake in Hong Kong, supply drinking water to Hong Kong citizen. Monitor water quality is one of the most important job for government. It is a big reservoir and cost much labor and time in such routine work. So the Water Supplies Department decides to introduce unmanned vehicle for automatic water sampling and online mobile water quality monitoring.

- ESM30 autonomous boat
- Shore station
- YSI EXO2 Multi-parameters probe
Hong Kong Plover Cove Reservoir
Oceanalpha provide autonomous water sampling and monitoring boat ESM30, Water supplies department offer existing YSI EXO2 probe, whole system integration was developed by Oceanalpha to make sure successful water quality data acquisition.
Boat launch and Base Station PC operation at shore, the boat will follow the preset trajectory under GNSS navigation to collect water samples and acquire online water quality data such as temperature, PH, Dissolved Oxygen, Conductivity and Turbidity etc.(Depend on the configuration of sensors)
Water quality data can be observed in PC and after mission completed, sampling report and water quality contour map will be output.
ESM30 boat is an autonomous platform designed for water quality sampling and monitoring in lake, reservoir and rivers, it can be integrated with different multi parameters probes for water quality monitoring, especially bring great benefit to big area lake and reservoir.
