How does Singapore ensure there is enough water supply for all?

Singapore depends on four sources for its water supply – local catchment water, imported water, NEWater and desalinated water. Known as the Four National Taps, this diversified water supply strategy ensures Singaporeans of a robust supply of water for generations to come.

How does Singapore manage water supply?

In 2005 Singapore opened its first desalination plant, which is one of the largest in the world and provides 10% of the city’s water supply. … With campaigns and economic incentives per capita water consumption is continuously being reduced and is now down to 155 litres per person per day.

How does Singapore ensure water sustainability?

Reservoir in the City

NEWater, Singapore’s success story and a pillar of water sustainability, is a high-grade reclaimed water produced from treated used water that is further purified using advanced membrane technologies and ultra-violet disinfection, hence making it ultra-clean and safe to drink.

How does Singapore increase water supply?

With separate rainwater and used water collection systems, good land use planning policies and strong environmental controls, the collected rainwater is protected from pollution. 2.

How does Singapore used water?

Singapore is 100 per cent served by modern sanitation today. Used water is collected through a network of sewers that leads to the water reclamation plants. Currently, there are four water reclamation plants serving a population of over 5 million.

To keep Singapore’s water clean, soil pollution must also be controlled, as pollutants in the soil can enter the water system as run-off or groundwater.

How does Singapore recycle water?

NEWater is recycled from treated sewage (‘used water’) and produced using a rigorous 3-step purification process involving ultrafiltration/microfiltration, reverse osmosis (RO) and ultraviolet (UV) disinfection.

Why is there a need for Singapore to have sufficient catchment areas?

With an area of about 710 km2 and growing urban areas, Singapore lacks the space to collect and store all the rain that falls on it. Through a network of rivers, canals and drains, rain that falls on two-thirds of Singapore’s land area is channelled to our 17 reservoirs.

Why is desalination important to Singapore?

Desalination is an energy-intensive water source. Singapore currently uses reverse osmosis for its desalination, which uses about 3.5kWh/m3 of energy to make seawater drinkable. This process produces pure drinking water by pushing seawater through membranes to remove dissolved salts and minerals.
