Water Efficiency Management Plan

Overview

The requirements of Water Efficiency Management Practices, under Part IVA of the Public Utilities (Water Supply) Regulations, came into effect from January 2015.

Und​er the Water Efficiency Management Practices, it is mandatory for large water users with net water consumption of at least 60,000 m3 in the previous year (i.e. qualifying consumers) to:

1. Submit a notification to PUB by 31 March (for specified consumers*) or 30 April (for non-specified consumers) for their different sites meeting this water consumption threshold. 
2. Install private water meters at key water usage areas within their premises by 30 June to track and monitor water usage.
3. Submit their annual Water Efficiency Management Plan (WEMP) to PUB by 30 June for at least three consecutive years.
4. Appoint at least one Water Efficiency Manager by 30 June


* Specified consumers - Consumers who hold one or more water accounts with PUB for water supplied to the site and the volume of water used under these account(s) in the preceding calendar year is at least 60,000 m³.

The Water Efficiency Management Plan allows customers to:

  • 1. Methodologically understand the breakdown of water usage in their premises and develop a

  • 2. Identify areas to further reduce consumption and raise efficiency
  • 3. Establish an action plan which identifies measures in water savings, priorities and implementation timelines
