What is the current area of water catchment in Singapore?

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 NEWater not used for drinking?

However, the high cost of production and unproven reliability meant it could not be rolled out. By the 1990s, the cost and performance of membrane technology improved by leaps and bounds. In 2000, PUB commissioned a full-scale demonstration plant that could produce 10,000 cubic metres reclaimed water a day.

Does Singapore still buy water from Malaysia?

Do we still import water from Johor? Yes. Under the 1962 Water Agreement, we continue to draw 250 million gallons of raw water per day from the Johor River. In return, we are obliged to provide Malaysia with a daily supply of treated water up to 2% (or 5 mgd) of the water supplied to Singapore.

How is catchment area calculated?

This capacity can be calculated using the following formula: Annual rainfall (in millimetres) x Roof surface area (in square metres) = Roof catchment capacity. This is an important figure to understand so you can design a Rain Harvesting system and choose a tank size that will meet your water volume requirements.

What is a protected catchment area?

Protected Catchments In 1971, a Water Planning Unit was set up under the Prime Minister’s Office to study the scope and feasibility of new conventional water sources such as harnessing yield from unprotected catchments and unconventional water sources such as water reuse and desalination.

Is Singapore water made from pee?

Turning urine into beer in Singapore: NewBrew is made out of a liquid which is recycled from sewage, filtered, and pumped into Singapore’s water supply. NewBrew is made out of a liquid which is recycled from sewage.

Does Singapore recycle sewage water?

Recycled wastewater can now meet 40% of Singapore’s water demand, a figure that is expected to rise to 55% by 2060, according to the country’s water agency. While most is used for industrial purposes, some of it is added to drinking water supplies in reservoirs in the city-state of 5.7 million people.

Can Singapore sustain water?

Singapore has NO large rivers, natural springs or glaciers. Through careful planning, we have been able to grow our water supply to meet our needs over the years. Nevertheless, we have to continue planning ahead, innovating and investing in research and development.
