Our Water Heroes #5 – Tay Manjun
Our Water Heroes

"Ever-Ready" – Water Quality Department (WQD) Manjun Tay describes her team as having to be alert 24/7 to carry out prompt investigations on water quality issues when needed. As a chemist, Manjun is responsible for water quality testing, where she analyses water samples collected from source to tap – including reservoir, sea, river, treated water, NEWater and desalinated water. Besides water quality testing, Manjun's team perform calibration and quality checks on analytical instruments to ensure data accuracy and reliability. By measuring test parameters such as pH, conductivity and turbidity, she monitors the trend of water quality of each water matrix and highlights anomalies to PUB's operations departments. This comprehensive water quality management programme helps to ensure that Singapore's tap water is well within World health Organisation (WHO) standards.

Never one to settle, Manjun and her team worked together with an external vendor to develop a new integration system that improves work productivity and effectiveness of water testing. The Automated Laboratory System (ALS) was introduced at the end of 2017 to reduce manpower, human error and manual testing time while ensuring data accuracy and reproducibility, hence protecting the integrity of the water samples.

When asked what is her greatest satisfaction at work, Manjun feels blessed that she is playing a big role in safeguarding Singapore's water supply, and highlighted that her recent overseas trips to less developed countries where water is very scarce and not safe for drinking makes her appreciate her work more.

"I feel proud when I see the public and visitors feel safe drinking our water straight from our taps."
