a few hours. Once installed, configuring the system took
approximately 10 minutes to program.

Table 4 shows a 66% reduction in associated annual CO2
emissions is possible for a single garden bed by incorporating
rainwater collection and implementing drip irrigation
instead of manual watering.

savings in labour costs as volunteers could be redeployed for
other tasks within the mosque.
Furthermore, the simplicity of the eco-solutions
demonstrated the feasibility of adopting drip irrigation
systems at other mosques in Singapore. This initiative is easily
scalable, with approximately 50% of Singapore’s 69 mosques
potentially able to undertake similar initiatives. Such
widespread adoption could lead to a substantial reduction
in associated CO2 emissions. Moreover, this project raises
