Harassment by local corporator/Nagarsevak

Hi, I am staying in Tehsil place where I own plot and home for residence. At one side of my plot, agricultural land is there and at other side homes of other members in society. Earlier, drainage and sewage water was going to that agricultural land. Since last 3 years that has been blocked by land owner and now sewage water has been accumulated on road in front of my plot and home. Registered written and verbal complaints many times in last 3 years to municipality but no action was taken and my plot has been severely damaged. Also it has become hazardous to health. So I decided to block the gutter from other end so sewage water will not come in from of my place. But local corporator and other society members are threatening and harassing me. And enforcing me to allow to dig a big pit to accumulate water in front of my place. So my questions are 1) Is it legal to allow to accumulate sewage and drainage water in residence area? 2) Is it legal to dig such pit on road in front of residential place? 3) What legal action can be taken against this bullying and harassment by other society members and corporator? Many thanks for your advice on this!!
