The excessive usage of treated tap water in community gardens is not ideal since tap water treatment in Singapore is energy-intensive and consumes large quantities of chemicals and materials. The objective of the project is to provide community gardeners with a reliable, low cost and water-conservative rainwater harvesting system to complement or replace their existing water source. Our designed system could 1) integrate with the current roof drainage systems; 2) provide gardeners with easy access to high capacity water tanks; 3) filter collected water to allow usage in current irrigation systems. Our focus group, comprising community gardeners from Bukit Batok Cosy Garden, is receptive to the idea as our water collection system could sustain gardens for up to 1 week per full high capacity tank. Hence, we conclude that the construction of this system would act as a useful alternative water source for community gardens.
