Singapore uses 430 million gallons of water every day, and PUB is responsible for making sure this water is safe to use and adequately supplied. To enhance its oversight and control of the entire national water system, PUB has a multitude of sensors and monitoring systems installed all across the water loop.
With numerous sensors it may be possible to develop intelligent systems that help verify and validate sensor readings to ensure that water plants will always have the most accurate information of its water systems. Such systems can also pin-point potential issues with sensors at the earliest possible opportunity.
Beyond the traditional sensors measuring established physical, chemical and biological parameters in water, PUB is expanding its library of sensor platforms to include newer and more challenging indicators of water monitoring, such as taste and odour detection at low concentrations in real time.
Sensors are also used for process control. One area for significant innovation is in the autonomous control of coagulation dosing due to fluctuating raw water quality. A solution capable of real time assessment of water quality to determine the amount of coagulation dosage could provide significant savings in terms of amount of chemicals that are used and ensure better water quality.
