Singapore has high water consumption per capita and 45% of it comes from usage. 10% is from the water basins and 16% is from flushing toilets by volume. We aim to reduce the water usage in flushing toilets. Our objective was to make an effective product that recycles water basin greywater to flush toilets, with no changes to their toilet usage. We measured the ability of our product to save water by measuring the amount of time it took to empty our greywater tank and conducted a survey on the receptiveness of our product and supplemented it with a focus group discussion to obtain details on their opinions on our product. 95% of people were satisfied with the ability of our product to save water, 77% reported no changes to their toilet use and our product can save 32L per day. Thus, our product recycles greywater effectly and is convenient for the user.
