Siruthuli launched a project named ‘Nalla Thanni,’ an initiative aimed at treating the water bodies which has been contaminated and polluted by the entry of sewage water and making the water reusable.
The initiative was announced by Vanitha Mohan, Managing Trustee of Siruthuli, during a press meet held on April 9, 2025. Sathish, Trustee of Siruthuli, and Krishnaswamy, Steering Committee Member, were also present and emphasized the need to prevent sewage waste from entering water bodies and urged people to reuse water.
In the press meet, they mentioned that Siruthuli has been working to rejuvenate the Noyyal River System and has been engaged in desilting several system tanks, village ponds, and check dams. Despite these efforts, they expressed concern that their work is being undermined by the ingress of sewage into the river system.
Siruthuli highlighted the consequences of the current situation, stating that the Noyyal River System is plagued with sewage, and all the system tanks are filled with sewage. A high level of fecal coliform (up to 90,000 MPN/100 mL) was recorded in one of the water bodies.
With water sources being polluted, all agricultural products are at risk of contamination. Additionally, the presence of large deposits of sludge in water bodies prevents percolation, which affects the augmentation of groundwater resources.
By mentioning the above, Siruthuli stated that it is imperative to make efforts to treat all sewage and reuse it for non-potable applications, which would help reduce the extraction of groundwater. This led to the creation of Project ‘Nalla Thanni’, aimed at treating sewage for reuse.
They also mentioned that the Coimbatore City Municipal Corporation (CCMC) has initiated efforts to treat sewage at several centralized locations by installing the necessary underground sanitary sewer systems.
Dispose the Waste Properly

“Hospital waste is a great threat in polluting water bodies, as it contains pathogens that spread viruses and can lead to diseases among communities,” said Vanitha Mohan. She also mentioned that reusing water is achievable if people are disciplined. She emphasized that people should be aware of the importance of segregating waste and disposing of it properly. With the support of the government, if people follow such cautious practices, this goal could be achieved with great success.
She also emphasized that the government should place more focus on the influx of waste into water bodies.
She also highlighted that newspapers should dedicate a separate column to the topic of waste, which would raise awareness among people and help in achieving the aim of ‘Nalla Thanni.’ Vanitha Mohan further suggested that we can commercialize water reuse, which is highly capital-generating and supports the environment.
