Intermittent water supply

Many people around the world do not have access to water 24-7. The World Health Organisation has estimated that approximately one-third of  piped water is intermittently supplied in Africa and Latin America and more than 50% in Asia[1].  Pressure transients following interruptions can increase the risk of pathogen intrusion and other water contamination events. Understanding the true health impacts of intermittent water supplies are partly constrained by a scarcity of water quality data.

This study is employing citizen science to sustainably establish local data collection networks which will enable real-time, spatial water quality monitoring. Combining citizen science data, modeling and exposure assessment may provide insights which are beneficial for environmental health risk assessment.

Chotiwat obtained a BEng with distinction in Environmental engineering from KMUTT, Thailand. Subsequently, he completed an MEng and was a recipient of “Best thesis award” from the Department of Urban Engineering of the University of Tokyo.

After working for the Sembcorp-NUS corporate laboratory, he then enrolled at Imperial College London as a PhD student under the supervision of Professor Michael Templeton in 2021.
