The first toilet-to-tap project at Keshopur was inaugurated on Thursday by Delhi CM Arvind Kejriwal, where he drank the water treated by sewage plant to break the stigma attached to it.
The plant uses a bio-filtration Nano membrane filtration technology where the raw sewage is screened and then passes through five- layered biofilter. The treated sewage is then pumped into size 0.001 measuring micron membrane system where water is chlorinated and is made available for drinking.
The same technology we can also use to clean our Tapi River which can ultimately help Surat from many issue like river pollution by industries and many more. The treated sewage water can be reuse. wonderful initiative by Delhi Govt. to sort out their water availability problem.
The project ‘Sujala Dhara’ launched by Delhi Jal Board in collaboration with an NGO Sana, will run on solar energy and can generate 25 million litres of water per year. In a positive effort to fight the “yuck factor” attached with the sewage treated water, the plant water will be first supplied to Delhi Secretariat and offices of Delhi Jal Board.
Potable water is currently being produced from treated sewage water in some countries such as Belgium, the USA (Arizona, California & Washington D.C.) and Singapore.
Today, when water inadequacy is a pertinent issue, water from treated sewage can be a successful way of dealing with the crippling water shortage that many a time leads to drought like conditions.
