PUB explores groundwater in western and southern Singapore

SINGAPORE - National water agency PUB is looking into the potential of tapping underground water sources.

The agency said on Friday that it has called a tender for consultancy services to study the potential of tapping aquifers and other underground water sources in the western and southern parts of the island, in an area known as the Jurong Formation.

The three-year Groundwater resource assessment in Jurong Formation study will be awarded in July 2013.

Here is the press release from PUB:

SINGAPORE - National water agency PUB has called a tender for consultancy services to study the potential of tapping aquifersand other underground water sources in the western and southern part of the island, in an area known as the Jurong Formation.

Titled "Groundwater resource assessment in Jurong Formation", this three year study will be awarded in July 2013.

The study comprises three key areas:

  • a. Development of groundwater flow model of Jurong Formation
  • b. Field Investigation Programme
  • c. Validation Study

Over the last 50 years, through integrated water management, and investments in R&D, PUB has put in place a long - term water supply strategy called the Four National Taps.

The Four National Taps comprise local catchment water, imported water, ultra-clean, high-grade reclaimed water branded as NEWater, and desalinated water.

The Four National Taps has ensured a robust and sustainable water supply for Singapore. Singapore's water demand currently stands at approximately 400 million gallons a day (mgd), and is projected to almost double by 2060.

With competing demands for land for other uses such as housing, industries and other services, it will be increasingly challenging to build new reservoirs to meet our water needs. To enhance the long term sustainability of Singapore's water resources, PUB is always on the lookout for new water sources.

There are potential solutions in the form of naturally occurring aquifers and groundwater.

"Through this study, we are exploring the presence of deep aquifers within Singapore's geology and if it is possible for us to tap on this water source," said Mr Harry Seah, PUB's Chief Technology Officer.
