There are altogether 17 reservoirs in Singapore. Each of the 17 reservoirs has at least one real-time water quality
sensor. Several aspects have been taken into account: turbidity, temperature, pH, conductivity, chlorophyll A,
dissolved O2. 15 - 20 minutes data point are taken
There is an estimate of 83 real-time sensors across our 17 reservoirs. Altogether, there are 49 real-time water
quality sensors and 34 real-time water level sensors across all our local reservoirs.
