PUB, together with SPRING Singapore and industry stakeholders, have developed a national standard Singapore Standard SS 577:2012 on water efficiency management systems. The Standard includes a set of framework and guidelines as well as suggested tools and best practices for water users to adopt and improve on their water usage and efficiency.

It specifies requirements applicable to water usage, including monitoring, measurement, documentation and reporting, design and procurement practices for equipment, systems, processes and personnel that contribute to water efficiency. The standard facilitates organisations in preparing their Water Efficiency Management Plan (WEMP).

Purchase the Standard from the Singapore Standards eShop.

PUB has also worked with the Singapore Accreditation Council (SAC) to develop a programme to accredit certification bodies to certify water users meeting the SS 577. Organisations are encouraged to adopt SS 577 and apply for certification. They can apply for funding under PUB’s Water Efficiency Fund (WEF).
