A Plant in New Delhi will turn Sewage into 66,000 Litres of Drinking Water Daily

The sewage water treatment plant will treat the water in five layers and can produce 66,000 litres of drinking water everyday. To make more people open to the idea, the treated drinking water will be sent to government offices.

With the never dying water crisis and keeping in consideration how precious every drop of water is, Delhi has taken an impressive step to treat sewage water and turn it to drinking water quality.

A decentralized waste water treatment plant in Keshopur will treat the water and supply to nearby areas. The pilot project by Arvind Kejriwal government is named ‘Sujala Dhara’ and was launched in collaboration with NGO SANA.

The technology is already being used in the US and will be replicated in India to purify water. It involves treating water through five levels to make it of drinking quality. The plant can run 24 hours a day producing 4,000 litres of drinking water every hour. The technology has been designed by Absolute Water, an integrated water management company.

The plant that uses bio-filtration nano membrane filtration technology will run on solar power and has a capacity of 25 million litres per year.

Raw sewage will be screened and then pumped through the biofilter. The water will be treated in five layers of organic and inorganic material including earthworms, cotton extracts, bacteria, organic sand, pebbles, stones, etc.

The treated water will then be sent to a membrane system which will make chlorinated and it will then be available for drinking.

The plant which was set up at a cost of Rs. 55 lakhs can produce 66,000 litres of drinking water every day.

As people might show resistance in accepting the treated water, the government has planned to package the water in bottles and send it to government offices. Once people see the CM and other senior government officials drinking the water, they will eventually be open to the idea.

The government plans to set up six more plants by the end of the year. Though some of them might not have the same technology but the water will be treated to get bathing quality water from these units.
