Delhi on Wednesday signed an agreement with Singapore to set up waste water treatment plants that will generate ‘new water’ for the city’s consumption. ‘New Water’ as it is popularly called is treated sewage and waste water that is being increasingly used in cities where water is in short supply.

The waste water is treated extensively and made fit for use. Singapore has an expertise in setting up ‘new water’ plants and is considered a successful model of waste water recycling and reuse.
