Managing Singapore’s Water Demand
Against the backdrop of climate change, coupled with the increasing
demand for water in tandem with economic and population growth, it is
crucial that we conserve water as it is a limited and invaluable resource.
In Singapore, our water demand is projected to double by 2065, driven
largely by the non-domestic sector, which is expected to account for twothirds of future water needs. Consequently, the non-domestic sector’srole in water conservation and sustainable management has become
increasingly critical. The call for visionary leadership, innovative solutions
and inspiring engagement has never been more urgent.
The Singapore Watermark Awards (SWMA) recognise organisations that
demonstrate outstanding leadership and accomplishments in promoting
the water sustainability agenda in Singapore. Award winners exemplify
the principles of water conservation, stewardship and advocacy, which
are essential for ensuring a sustainable water future. As we honour ourwater champions, we aim to inspire others to pledge their steadfast
commitment to water sustainability and join us in safeguarding
Singapore’s water future.

Mee Toh School is deeply passionate about water
education, advocacy and conservation. With their effective
water conservation measures and educational initiatives,
they have emerged as a trailblazer in the education sector,
winning the prestigious SWMA 2024.

Hands-on Water Conservation
At the core of Mee Toh School’s water conservation
initiatives are its practical and sustainable solutions aimed
at saving and reusing water. One notable example is theirrainwater collection system, which harnesses rainwaterSingapore Watermark Awards
Winners 2024
for use in the cleaning of common spaces, wateringof plants, and even in students’ projects. On campus,
sensors are installed at taps and water coolers to reducewater wastage. In addition, to ensure that undergroundwater leakage does not go undetected, operations staff
monitor water usage by checking water meters daily.
Between 2019 and 2022, the school successfully lowered
their annual water consumption by an impressive 30%,
reflecting their proactive approach to water conservation.

Educating Future Generations
Water sustainability is a part of the school’s Environment
Education curriculum, instilling a sense of water ownershipand responsibility in their young students. For example,
Primary 5 students apply what they learn in the various
subjects and come up with innovative prototypes in theirattempts to address water sustainability issues. A groupof them showcased these prototypes at the Singapore
World Water Day 2023 celebration event. They also
designed posters in their mother tongue languages, andsome of these were put up in school to advocate for water
conservation.
Other initiatives include water rationing exercises topromote responsible water use and nurture an appreciation
for water as a valuable resource among the students.
Parent volunteers, together with Environment Champions,are also involved in supporting the exercises and sharing thewater conservation messages.

Mee Toh School is alsoa recipient of the Water
Efficiency Awards

Empowering Water Advocates
The “Environment Champions” are a group of students
who organise projects for environmental causes andrally the school community on water sustainability.
They reach out to their peers through talks, posters
and facilitate the pledging for water conservation by
fellow schoolmates. Despite the challenging times of
COVID-19, the Environment Champions still reached out
to their peers through online platforms using learning
packages on water conservation that they designed.
A group of Environment Champions even invented the‘Wishy-Washy’ device, a prototype that uses rainwater toclean recyclables without using any additional water. It uses
a sensor and Micro:bits (a pocket-sized computer) to detect
the recyclables before activating the irrigation of rainwater,
ensuring that water is used in the most efficient manner.

Through the school’s Applied Learning Programme, students
develop projects and prototypes like the “Wishy-Washy”,
which uses harvested rainwater to clean recyclables.

“

The award is an affirmation of the effortsof the school community, stakeholders
and partners, put together over theyears. No effort is too small and we takeone step at a time. Our students are in
their formative age. By teaching themthe values, knowledge and skills to form
good habits of water usage from young,we hope to see them grow up with theconfidence to influence many more.

Improving the Efficiency of Bus Washing

Water Recycle System

SBS Transit is the largest public bus operator in
Singapore, operating over 200 bus routes with a fleet
of more than 3,500 buses.

VIS is a wholly own subsidiary of Vitasoy International
Holdings, a leading international manufacturer anddistributor of plant-based food and beverages.

SBS Transit’s bus washing machines were equipped withsystems capable of collecting, filtering and recycling
approximately 80% of the water utilised in the bus
washing process.

VIS developed an innovative Water Recycle System thatuses collection tanks to intercept overflow water fromtheir machines used to manufacture tofu, then channels
this water through a filtration bag system to remove large
impurities from the water. The water that has passed
through the system can then be reused in multiple inhouse activities, such as general cleaning and equipment
washing.

By SBS Transit Ltd

In their quest for continuous improvement, they installed
additional pumps which helped to transfer a greater
volume of filtered recycled water back to the watertank. This significantly reduced the need for fresh water,
leading to a more water-efficient washing process.
They took innovation another step further in their final
wash process by reducing the size of the spray nozzles
to 1/8 inch. This effectively decreased flow rates whileboosting water pressure to facilitate optimal cleanlinesswhile reducing water consumption. By simply switching
the nozzles, they save about 25% of water used per
bus wash, showing that strategic enhancements andinnovative adaptations can go a long way in optimisingresource utilisation and conserving precious water.

By Vitasoy International Singapore (VIS)

In the initial stages, the project encountered roadblocks,
such as frequent choking of the filtration bags, which
compromised the flow and quality of the recycledwater, placing undue stress on the system. Undeterred,
VIS persevered in its vision and came up with effective
solutions. They collaborated with project stakeholders
to develop a cleaning plan that included redundantfilter bags as backups to reduce downtimes. They also
involved engineering control to implement alarm sensors
that would alert operators of system abnormalities fortimely intervention and rectification.
Through diligent implementation and optimisation, VIS’s
Water Recycling System has now achieved the potential
to save up to 30m3 of water every day.

The auto bus wash process uses recycled water for washingand fresh water for the final rinse process, minimising overallwater consumption.
