Harassment from society

The problem is about leakage faced by the flat below us because of the rains which are collecting in the balconies. More than a year back, the society took a decission to do external repair of the building because they claimed that 95% of the flats were facing leakage. Once the work started, the workers came to my house in order to break the drainage pipes in my balconies. I asked them what was the reason for that and they mentioned that it was the society's decission. I called up the seceratory to discuss the matter as removal of drainage from the balconies would lead to flooding in the monsoons. He didn't seem to care and said to install a sheets at my own expense to prevent flodding in my balconies. I did not do that ofcourse. As a replacement of the drains, the society installed external pipes for the AC and for the washing machine. The joke is that the pipe for the washing machine is installed half a foot high like as if water drained from the washing machine will fly up to the outlet. Honestly, this is a total waste of money and foolish decission made by the society. The monsoons came and as predicted, water started flooding in my balconies and the below flat began to face leakage problems. They came to me to fix it. I advised to take the matter up with the society as the problem has been caused because of them. They did that and the seceratory kept sending workers to apply cement to seal any cracks in my balcony. I told them to stop doing this and to provide permission to drill a drainage outlet from my balconies and fix a pipe, which they refused on grounds of it damaging the beam. The society refuses to take responsibility for this and asked the below flat members to solve the problem between ourselves. So the owner of that flat asked me to install the sheets as suggested earlier by the seceratory, in all my balconies at my own cost. He refused to bear any cost of the same. I bluntly told him that if he wants to get the sheets fixed in my balconies, to pay for it in full or forget it. I'm not going to pay anything. The reason I refused bluntly, is because the society refuses to take responsibility for it and the below flat members, supported the society in the decission of removing the drainage pipes. So these people are working together against me. Now, I want to highlight another important thing here. The seceratory runs a business of modifyling the flat interiors. He has taken contracts from many members in the building to extend their rooms into the balconies. This involved breaking the wall that stands between them. As part of this, the building has taken a consistant hammering due to breaking of walls in those flats which could be a possible cause of weakening the building structure and leading to leakages. He even shamelessly suggested that I do the same in my house. Now, from this, I see this all as a money making racket. They create problems and sell solutions. The owner threatens me with law suit. Kindly advise.
