Municipal Office Badangpet — Open drainage problem

I resident of sai Gokul nivas (beside bheesma nagar) colony..
The open drainage nala in our colony is totally filled and there is no flow.. The river is flooded near the colony due to heavy rains. Due to this water remains stagnant and mosquitoes are increasing.. It even results in faul smell.I kindly request you to clean the surroundings
