Kote mariappa Lane, shri Dharmaraya Temple Street, near abbas Khan College bangalore 560002
Every 15 days or once in month we face chamber blockage in our road this is happening from more than 2 years. Only temporary solution is provided.
There are 3 chambers in the road. If the first chamber get fixed, second one get blocked, next third one. We need to raise complaint regularly for each one. It takes almost a week to resolve problem.
Sewage water gets mixed with borewell water.
Mosquitoes in the evening, very bad smell.
In the same road we have abbas khan college and lourdes school .
Underground water is very precious for our country mixing with sewage is loss for nation.
Request the authority to provide a permanent solution for this on behalf of residents of kote mariappa lane, shri Dharmaraya Temple Street, Bangalore
