Singapore's Water Supply

Singapore does not have much water supply but over the years,it has increased its water supply with many ways.
The water resources of Singapore are especially precious given the small amount of land and territory in Singapore's geography while having a large urban population in the city-state. Without natural freshwater lakes, Singapore relies on four water sources:

• rainfall, collected in reservoirs or water catchment areas (about 20% of supply in 2010),
• Imported water from Malaysia (about 40% of supply),
• Reclaimed water (producing NEWater) (30% of supply), and
• Seawater desalination (10% of supply).

This "four tap" strategy aims to reduce reliance on supply from Malaysia by increasing the volume supplied from the three other sources, or "national taps".Let us look at these 4 sources closely.
