Stipulated Standards & Requirements of PUB, Singapore’s National Water Agency on Mandatory Water Efficiency Practices.

The wafer fabrication, electronics, biomedical and pharmaceutical industries are among the largest water users in Singapore, accounting for about 20% of the current non-domestic water demand. There is also high potential for water recycling in these industries, as their used water streams can be effectively recycled when segregated at source. In addition, some wastewater streams are fairly clean, making them both technically feasible and commercially viable to recycle with minimal treatment required.
This PUB’s Stipulated Standards & Requirements on Mandatory Water Efficiency Practices is issued under Section 40 of Public Utilities Act (PUA) and under the Public Utilities (Water Supply) Regulations. It specifies the recycling requirements for new facilities in the Wafer Fabrication, Electronics, Biomedical and Pharmaceutical industries, at both the design stage and operation stage.
