Small piped drinking water systems pose a unique challenge to the regulatory authorities since the owners/operators of such systems often lack technical expertise, resources and organizational controls to effectively operate their treatment systems, unlike the large utilities that have the economy of scale to address these issues in an optimal manner. With the discovery of new non-conventional sources of water and the continuous development of low-cost water treatment processes, the number of small suppliers is likely to grow worldwide in the future, especially in those remote areas/islands where drinking water is not easily available. In order to ensure that these suppliers are able to detect any health risk to the consumers in a timely manner, it is imperative to develop a water sampling plan that is comprehensive enough, yet flexible and practical to implement. This paper highlights Singapore's regulatory experience in prescribing, developing and monitoring the implementation of piped water sampling plans by small water suppliers.
