Inefficient solid waste management results in waste piles that contribute to urban flooding in cities like Chennai. While most citizens blame civic authorities for the lapse, are they doing their bit?

Come November, along with swollen waterways and flooded streets, another prominent image flashed repeatedly on television screens is that of mountains of mixed garbage. Chennai’s solid waste headache is by no means entirely monsoon-related. But the issue manages to capture the media’s attention around this time of the year mostly because unregulated dumping tends to disrupt waterways in many parts. Intensified waterlogging and heightened public health concerns closely follow.

My apartment is in Madambakkam near Tambaram, Chennai and there is no drainage facility in my area. We have 3 soak pits around my flat for the sewage water (from bathroom and washing machine). However, a pit at one corner is adjacent (11 feet) located from my neighbour's borewell. The borewell is about 350ft deep. There have been no issues for the past 4 years. But, now they are complaining that their borewell water is getting contaminated because of my pit. Will it get contaminated? Is it okay for me to continue with the pit? Or what remedial action should I undertake?

Background: Our Flat is based in Tambaram, Chennai. There are 6 flats in an apartment. We share common overhead concrete tank. During summer we face acute water shortage problem. Even after starting the pump and it is running for half an hour, we won't get a drop of water. We are living in ground floor. Since there is lot of suffering especially on Sunday where all the members of family will be present and water needs will be more, I went inside the overhead tank to check what is wrong.

I live in Chennai. Our borewell is not yielding water and many of my neighbors face the same issue. plumber suggested us to drill another borewell. We do not have space , as our first floor extends to cover the entire plot area, hence the only way which our plumber suggests is to drill hole in the roof in order for the drilling machine to fit. Is there any other option instead of drilling a hole in our roof? Appreciate the help.

We presently have BRIM media over coarse aggregate of sand and pebbles in a 200 litre drum. Well water is pumped into this drum and the clean filterate from the bottom goes into our water tank by gravity. However this installation is over 10 years old and I think the BRIM media is not effective. If simply changing the BRIM media should resolve the problem, I will try that. I am not sure that this is the best solution since most vendors I call are only keen on selling a more expensive solution involving tanks and pumps.
