A new technique to treat dry sewage

The city has been successful in treating sewage water. Nine sewage treatment plants (STP) treat 486 million litres per day. The government earns about Rs 10 lakh per year through the sale of secondary treated sewage. Going a step further, Chennai Metropolitan Water Supply and Sewerage Board is planning to adopt a technology from the Bhabha Atomic Research Centre (BARC) to treat dry sewerage sludge that is left out in the STPs.

Though sewage water is treated and reused, there is no proper method to dispose of the sludge that is left behind. A matter of concern to health and hygiene but it is a rich source of nutrients and organic carbon that are necessary for the soil. The technology from BARC will help kill the pathogens, reduce the odour and make the sludge suitable for other applications. One such facility likely to come up  in Chennai will solve our entire dry sewerage problem. The treated sludge from this process is rich in nutrients and can be used as manure.
