Conclusion:My whole team feels that the best and most reliable source of water supply is the NEWater. NEWater is the most reliable to us because we felt that if NEWater comes from used water which is usually from homes.Since Singapore has so many houses,we should not have any worry on not having anymore used water for the NEWater.So my group felt that it was the most reliable.It is also potentially unlimited and is a constant supply.It also enhances national security and self sufficiency.

Conclusion:
                    There are currently 17 such reservoirs  covering two-thirds of the island's landmass.Then there is NEWater which is essentially purified wastewater.There are currently five NEWater Plants in operation and they rpovide 30 percent of Singapore's water needs.Singapore currently has one such plant in opeartion.With competition of a second plant in 2013,desalination hill account for 30 percent of Singapore's freshwater needs.In addition to improving water supply sources,Singapore has also introduced water conservation and efficient-use initiatives.
Tap 3:Desalinated Water
-There is a SingSpring Desalination Plant in Tuas.
-It supplies 136000 million litres of desalinated water daily,which meets about 10% of Singapore's water needs.
-An integral role in Singapore's drive towards self-sufficiency.
-Meet future needs at an affordable cost.
Strength:Very reliable

Tap 2: NEWater
- NEWater is obtained after reclaiming used water.
- Treated used water is further purified, making it suitable for human consumption.
- With the addition of the fifth and largest NEWater plant at Changi, NEWater now meets 30% of Singapore's total water demand.
- It is said that by 2060, NEWater is projected to meet 50% of Singapore's future water demand.
- Strength: There would be a constant supply of NEWater as humans produce waste everyday.

Geography- Water Constraint

 Tap 1: Water from local catchment areas (Reservoirs)
- There are 14 reservoirs island wide.
- Half of Singapore is used as water catchments.
 Strength: There are frequent rainfalls in Singapore.
