The drain in front of the RO Water Plant at Triveni Circle in Kalyangiri is stinking as the water let out from the RO Plant is getting stagnant as it is unable to flow freely in the drain which is clogged. The stagnant water has become a breeding ground for mosquitoes. The authorities could use the waste water from the RO Plant for watering plants at the adjacent park thus utilising the waste water instead of letting it into the drain. Authorities concerned are urged to take steps to clean the drain at the earliest.
