Despite the diversity of water sources, imported water still accounts for more than half of Singapore's water supply for now.
Hence, the Government is rightfully concerned about the amount of water that the Linggiu Reservoir in Johor is holding ("Use less water, PM reminds as reservoir dries up"; Sunday).
Prime Minister Lee Hsien Loong has been urging Singaporeans to use less water, and I am heartened that Singaporeans are taking in the message to save water.
However, the focus should be on the non-domestic sector.
National water agency PUB has forecast that the non-domestic sector will account for 70 per cent of Singapore's water demand in 2060, a significant increase from 55 per cent currently.
This means that any practice that encourages water conservation in factories and companies will have a huge impact on Singapore's water usage.
More effort needs to be put into how factories and companies can use water more efficiently.
Nevertheless, water conservation practices start with our daily habits.
If every individual ensures that each drop of water is used wisely and efficiently, this mentality will be carried over to the workplace.
