37 housing societies get notice for 'flouting' STP rules in Greater Noida
Residents of different societies had complained to the GNIDA CEO that sewerage was being discharged into the drain without being treated through STP. In Greater Noida, it is mandatory for all the projects being built on an area of 20,000 square metres or more to build their own STP and keep it functional, the authority said.
