PUB confers two awards: Water Efficiency Awards (WEA) and Water Efficiency Awards (Projects) (WEAP) to recognise the top achievers in water-efficient operations and acknowledge the improvements by organisations in rolling out water-efficient practices.

Launched in 2017, the WEA recognises the most water-efficient organisations in each sector. Awards go to premises with the lowest Water Efficiency Index (WEI) and industrial plants with the highest recycling rates in their respective sectors. The next WEA will be given out in 2028.

The sector-based WEA is not open for nominations. PUB selects recipients internally using organisations’ data submitted each June under Water Efficiency Management Practices (WEMP).

To qualify for the WEA, a site's WEI or recycling rate must rank within the top 10% percentile of its sector. Recipients must also hold the Water Efficient Building Certification.

The Water Efficiency Index (WEI) measures water-efficiency performance by comparing water use with a business activity indicator that reflects the user’s operations.

WEI = Total water consumed ÷ business activity indicator.

Introduced in 2024 alongside the return of the SWMA, the WEA Projects (WEAP) category recognises innovative projects that significantly improve water-efficiency and set higher industry benchmarks. The next WEAP will be given out in 2028.

WEAP nominations were open to all non-domestic water users, including private companies, businesses, educational institutions, town councils and government premises.

Nominees had to be registered in Singapore and could nominate themselves or be nominated by another party. Only one nomination was permitted per project, although organisations could nominate multiple projects.

Eligible projects had to be commissioned between 1January 2025 and 31 December 2026, deliver measurable improvements in water efficiency, operate successfully, and comply with all regulatory requirements in Singapore. This eligibility period ensured that projects had sufficient operating time and data before being submitted for the WEAP.

Nominations were assessed against the criteria below, which may be revised for WEAP 2028.

• Performance: Demonstrated efforts and quantifiable results in reducing water demand from PUB.

• Innovativeness: Demonstrated innovative use of technology and process improvements to reduce water use or promote recycling.

• Project leadership: Demonstrated collaborative efforts to overcome unexpected obstacles and challenges.

• Success of the project: Demonstrated successful operation of the project in accordance with all regulatory requirements.

Notification of Results:
Awards recipients were notified in early August 2026.

On 25 Sep 2026, 34 premises received the Water Efficiency Awards while 4 premises received the Water Efficiency Awards (Projects) from Ms Goh Hanyan, Senior Parliamentary Secretary, Ministry of Sustainability and the Environment.
