Upon presenting the water usage reduction potential of Implementing Eco-Solution 1 resulted in a notable
Eco-Solution 1 to the Starlight management team, their reduction in monthly water consumption for the workshop
willingness to implement the eco-solution was evident, by approximately 50%, equating to approximately 28m³/
driven by the perceived business benefits and anticipated month (Table 4). This reduction in water usage translated to
cost savings in operational expenses. Encouraged by the an annual carbon emissions reduction of 480.48kg CO2/m³
supportive feedback from management, the ESI team was (see Table 3). This reduction in water usage translated to a

The ESI team conducted multiple company visits to Table 4: Comparison of water usage before and after

and dimensions. Subsequently, the team dedicated two
weeks to design the product. Figure 11 and 12 illustrate the
design drawings developed by the students.

According to PUB water pricing (7), water prices for industry
are $2.13/ m3, and annual cost savings therefore = 336 m³ x
Figure 11: Tank Dimension. $2.13 = $715.68.

Eco-solution 1 was fabricated based on the ESI Team's
design sketches, as shown in Figure 13. Before installation,
the ESI team recorded the water usage readings to
establish a baseline. On 15 Feb 2023, the product was
successfully installed and operated, as shown in Figures 14
and 15. During the installation, the ESI team encountered
challenges in joining and fitting the piping layout from the
central hose. However, with assistance from the fabrication
vendor, they overcame these obstacles and installed the
product according to the planned design. Subsequently,
the team conducted monthly visits to monitor water usage
and documented their findings over two months.
