The Tamil Nadu Pollution Control Board (TNPCB) on Tuesday mandated that even construction projects having a built-up area of less than 20,000 sq. mt. must obtain its consent to establish and operate a sewage treatment plant (STP).
A press release issued on behalf of the Member-Secretary said the directive was meant for effective monitoring of such plants. The TNPCB often received complaints that STPs were not being operated effectively, discharging untreated sewage into the nearby storm-water drain, vacant land and waterbodies, thereby causing pollution.
