Increasing Demand and Climate Change
The demand for water is expected to almost double in the next 40 years - a result of projected increases in industrial activity and population growth. Coupled with the uncertainty of weather patterns in the face of climate change, we cannot take it for granted that we will always have enough water.
In Singapore, we are lucky to have easy access to clean water from the taps. However, this also makes it easy for us to end up using more water than we really need. When clean water comes at the turn of a tap, it is easy to waste water without noticing.
Water wastage from pipes or water appliances often goes unnoticed as well. Loose tap fittings, malfunctioning toilet cisterns and leaking water pipes can all lead to a huge waste of water.
For instance, a typical leak from a kitchen can amount to 10,000 litres per year, which is over 6600 large bottles.
Steady Reduction in Water Consumption
Through PUB's long-term efforts in water conservation, Singapore's per capita household water consumption dropped from 165 litres per day in 2000 to 141 litres per day in 2019. We aim to reduce it to 130 litres per day by 2030.
Water Conservation Education and Outreach
PUB conducts community outreach efforts to raise awareness. The annual Water Conservation Awareness Programme sends volunteers to households with high water consumption to install water saving devices and share water saving tips. Participating households save up to 5% of their monthly water consumption. PUB’s 10% Challenge benefits the non-domestic sector by encouraging businesses to cut down 10% of their monthly water consumption, which also lowers their operational costs.
Preventing and Detecting Leaks
PUB replaces ageing water mains and pipes over the years to minimise leaks. Regular checks are also conducted on water meter readings to spot leaks.
Pricing Value to Reflect Its True Value
The use of sound economic principles in pricing water is important to keep demand and supply in balance. Under-pricing water leads to over-consumption. As such, the price of water in Singapore comprises what is needed to recover the cost of production and supply and a Water Conservation Tax to reflect the scarcity of water and the importance of conserving it.
Funding Water Efficient Measures
PUB’s Water Efficiency Fund (WEF) co-funds organisations, companies and community groups to implement water saving initiatives.
