In collaboration with a group of SMU undergraduates, the Restroom Association of Singapore (RAS) celebrated World Toilet Day 2007 on 19 November by paying tribute to "Toilet Cleaners- The Unsung Heroes".

Spun off from a Community Service Project initiated by a group of SMU students, the appreciation event was specially held for SMU's toilet cleaners from A & P Maintenance Services Pte. Ltd to commemorate this day. Highlights of the event include a montage made by SMU students in tribute to the toilet cleaners and a plaque presentation to SMU's toilet cleaners.
