What is Unaccounted-for-water? What caused it?
UFW refers to water lost in the network of pipelines between the drinking water treatment plants and the consumers. This water lost could be due to leakage or other reasons but often it is the lack of maintenance which causes the network to deteriorate over time.
In Singapore, we adhere to a comprehensive maintenance regime with all built facilities and infrastructure. We plan our system carefully and implement accurate metering at drinking water plants. We fix and replace pipelines on a regular basis.
