Integrated Water Quality Monitoring System and IoT Technology for Surface Water Monitoring

Abstract

Frequent water supply disruptions have been a nightmare to consumers especially in Malaysia. These recurring events occurred due to river contaminations at water intakes. The condition becomes worst during the spread of Covid-19 pandemic and the implementation of stay-at-home or lockdown order. The recent water supply disruptions badly affected about 1.2 million consumers in Klang Valley. Therefore, the water management system needs to be improved to prevent repetitive of massive water supply disruptions in the future. One of the approaches that can be implemented is by continuous monitoring of river water quality in real time basis, in order to assist the authority in monitoring river water quality, especially at the water intakes. Thus, the purpose of this study was to develop and validate a functional prototype to monitor real time surface water quality using IoT technology. This prototype potentially assists the authority to monitor the water quality, provide early pollution detection and warning, and plan mitigations of the river water pollution events.
