PUB looking for smart devices to monitor water usage during showers

Today Online 28 Apr 17;

SINGAPORE — National water agency PUB has called for proposals to mass produce devices that can provide real-time information on water usage during showers, as part of a demonstration project involving 10,000 households to show this method’s effectiveness in reducing water usage.

Through the request for proposals, which will close at the end of next month, PUB also aims to improve the features of current smart shower devices in the market, such as allowing data on water usage to be ported to personal smart devices, so that progress can be monitored over a period.

The Smart Shower Programme, set to begin in the first quarter next year, comes in the wake of a study conducted from July 2015 to March last year showing that each person uses five litres less water per day when there is real-time information on water usage during showers. Yesterday, PUB said such devices can potentially help households save about 3 per cent of their monthly water bill.

“Showering typically comprises 29 per cent of a household’s monthly water consumption. There is great potential to achieve substantial savings if we can change the user’s behaviour during his/her shower time,” said Mr Michael Toh, PUB’s director of Water Supply (Network).

Last year, households used 148 litres of water per capita per day. This figure is lower than the previous reported level of about 151 litres and just shy of Singapore’s target of 147 litres by 2020, although still a stretch from the 2030 target of 140 litres.

Water prices are scheduled to go up by 30 per cent over two rounds on July 1 this year and next year, with help being provided to most households.
