Understanding the effect of intermittent water supply on drinking water quality

There are nearly 1 billion people who obtain their drinking water through piped distribution networks that operate intermittently. Intermittent Water Supply (IWS) operations allow for periods of stagnation and depressurization that create conditions favorable for biofilm growth on pipe surface. Biofilms are complex microbial communities that are likely sources of opportunistic waterborne pathogens and can cause disease outbreaks. Flushing of the water pipes and re-pressurization, which occur at the start of each IWS supply cycle, cause the erosion of the biofilm and its transport into the bulk water, which can potentially contaminate the drinking water. This thesis describes the development and proof-testing of an experimental pipe testbed installed on the Nanyang Technological University (NTU) campus in Singapore.
