SINGAPORE- Indian national worker T. Rameshkumar, 31, spends three hours every week speaking to other workers in his dormitory about the importance of saving water.

He is among 20 workers living in Leo Dormitory in Kaki Bukit who have been selected to share water saving tips with some 4,300 residents.

The dorm has also installed water efficient taps, showers and urinals. Some $2.2 million was spent on these and other green features.

The dorm management says it is now spending 20 per cent less on utilities compared to its three other dorms which do not have these green features.

These efforts have allowed it to receive the Water Efficient Building (Web) (Basic) certification by the PUB.

Introduced in 2004, the certification programme aims to get businesses to incorporate water efficient systems in their premises. More than 2,600 buildings are part of the programme.

Second Minister for the Environment and Water Resources Grace Fu said Saturday that that Leo Dormitory is the second foreign worker dorm in Singapore to receive the certification.

Westlite dorm in Tuas got the Web (Basic) certificate last year (2014).

"(water efficient measures) will help the dormitories save a lot of water and money... I would like to encourage more dormitories to come on board," said Ms Fu.

She was speaking at the official opening of Leo Dormitory.

The original complex was torn down and rebuilt.

It re-opened in May last year after 17 months of construction which cost Leo's operator MES Group $42 million.
