Excess usage of sodium hypochlorite solution beyond the permitted level by the Tiruchirapalli city municipal corporation resulted in wasteful expenditure of Rs.1.53 crore and also exposed the general public to health hazards for three years, according to the report of the Comptroller and Auditor General of India Compliance Audit for the year ended March 2020.
During a press meet in Chennai, Vishwanath Singh Jadon, Accountant General (Audit-II), Tamil Nadu and Puducherry, said, “Audit noticed (March 2020) that against the norm of 20 litres per MLD laid down by the Directorate of public Health and Preventive Medicine, Chennai, the corporation was using 35 litres of sodium hypochlorite liquid per MLD for treating of water during 2016-17 and increased the same to 52.5 litres/MLD from 2017-18 onwards.” Besides this, stable bleaching powder at 2kg/MLD was also used as secondary disinfectant for 91 tanks at zonal level.
The report of the Comptroller and Auditor General of India, also pointed out that failure to assess the demand before developing new industrial estates resulted in unproductive investment of Rs.28.47 crore.
