Singapore CP 48 Code of Practice for Water Services
Water is essential for life, health and hygiene. It is also a precious resource that needs to be conserved and used wisely. In Singapore, the Public Utilities Board (PUB) is the national water agency that manages the water supply, water catchment and used water in an integrated way. To ensure the quality and safety of water services in Singapore, PUB has established standards and requirements for water fittings that are used in potable water service installations.


One of the key documents that stipulates these standards and requirements is the Singapore CP 48 Code of Practice for Water Services. This code of practice was first published in 1999 and revised in 2005 and 2018. It covers the design, installation, testing, operation and maintenance of water service systems, including pipes, valves, taps, fittings, tanks, pumps and meters. It also provides guidelines on water conservation, water quality monitoring and water leakage detection.
