Water Scarcity would become a history in Delhi as Singapore water re-use model, in which waste water is filtered and used again, is being studied to be replicated here, Chief Minister Arvind Kejriwal said on Monday.

Interacting with reporters at Rashtrapati Bhavan after attending the Padma awards presentation ceremony, Kejriwal said his government has already sent teams to Singapore to study its water supply model.

“Singapore does not have any water of its own. Almost 95 per cent of water comes from outside,” he said, adding it has developed a system where used water is filtered and re-used and in such a way water used in toilets goes to toilets after it is filtered and similarly waste water from kitchen goes to kitchen again.

“We have been studying how it is done. We plan to begin with 10 to 15 pilot projects on the same in Delhi in a month or so,” he said.

The water quality, after it is filtered, is as good as of mineral water, Kejriwal said.

If it could work in Delhi, “which I think it would”, there would be no water shortage in the city, the chief minister said.

The concept of recycling wastewater certainly isn’t new, with long-running initiatives already well underway in Israel, Spain, Scandinavian countries and the US. But with water re-use model, Singapore has quickly gained an international reputation for efficient recycling of wastewater. The initiative already supplies around one third of the country’s water demand, and that number is expected to grow to more than half by the year 2060.

Singapore’s water project has become an important model for the entire Asia Pacific region. Australia, too, has been purifying wastewater for years, though partially for different reasons.

Great Barrier Reef Faces Australian Floods Dirty Water

Dirty water from a flood crisis in north Australia has spread to parts of the Great Barrier Reef, placing it under stress, scientists have said. The floods are the result of weeks of devastating rain in Queensland. Some regions experienced the equivalent of a year’s rainfall in 10 days.

Aerial pictures show that run-off from one river has blanketed some reef areas more than 60 kilometres from shore, the BBC reported on Friday.

The UN calls the Great Barrier Reef, located in the Coral Sea off the coast of Queensland, the “most biodiverse” of all the World Heritage sites, and of “enormous scientific and intrinsic importance”.

Scientists fear the sediment-laden waters may be blocking out light and effectively “smothering” coral.

In recent weeks, run-off from several rivers has coalesced to affect an approximately 600 kilometre stretch of the reef’s outer edges, scientists said. The water has not dispersed due to its size and a recent lack of wind.

Frederieke Kroon from the Australian Institute of Marine Science said the nutrient-rich water had also sparked algae growth in some areas, turning waters “a thick blanket of green”.

The reef is already facing threats to its survival such as coral bleaching caused by warmer sea temperatures. It has also been damaged by cyclones. (IANS)
