When the Taiwan Environment Protection Agency needed to build two real-time, long-term monitoring stations on the Sun Moon Reservoir, it looked to Hydrolab for the critical measurement instruments. Sun Moon Reservoir, located in the center of Taiwan, is the country’s most important water source for drinking water, agriculture and power generation. The project required one monitoring station at the intake from the source river and another at the discharge to the drinking water treatment plant.

The EPA uses a Hydrolab DataSonde 4a, to measure temperature, DO, conductivity, salinity, total dissolved solid, pH, ammonium, nitrate, Chlorophyll a and transmissivity. In addition, the EPA uses the Carlson Eutrophication Index to improve the quality of drinking water.

The stations are equipped with solar panels and GSM Telemetry, which enable them work fully as unattended monitoring stations, requiring only periodic maintenance and calibration, which is conducted by Panwell Technology Company, Hydrolab’s dealer in Taiwan. The complete system includes Chinese operation software, which was designed and developed by Panwell and is supported by Hydrolab-Hach.
