Underground reservoirs could be S'pore's "fifth tap" - Channel NewsAsia: Experts said finding underground reservoirs of water could solve Singapore's problem of not having enough space to hold rainwater, and it could also prove to be the country's fifth tap.
The comment follows a recent tender called by national water agency PUB to study the feasibility of extracting groundwater from the southern and western parts of Singapore.
If the three-year study shows promise, Singapore could join a host of countries that source drinking water from the ground.
Groundwater could then add to Singapore's water supply that now depends on four sources -- imported water, catchment water, treated recycled water and desalinated water.
The four sources are referred to as the "four national taps". These sources provide for the nation's current water demand of some 400 million gallons of water each day. PUB said this number is projected to almost double by 2060.
