Singapore Consumption Trends
Presently, around 680,000 m3 (or 149.58 million gallons) of Singapore’s water consumption is sourced from catchment areas around the city state. This represents about 60% of the country’s daily needs. As of 2005, there are fourteen raw water reservoirs in Singapore (see map).

Singapore has adopted an ambitious plan to diversify its water sources, so as to minimize the influence of Malaysian water. Its “Four National Taps” program includes purchased water from Malaysia, treated wastewater (used mostly for industry), NEWater (advanced treatment of wastewater for human use), and desalinization. Moreover, Singapore has developed a new relationship with the province of Riau in Indonesia to import water via undersea pipeline. (See table for detailed statistics).
