Disconnection of water connection

My family lives in a one room kitchen under pagdi system. We are six members in a family. We are staying there since my grandfather's time about 50 Years. Firstly the land lord was a other fellow who used to take the rent including the water bill. Later he sold the property to another fellow who used to tk rent but water Bill section Was not written in it. But from About past 30 Yes. The water line is used by me and my neighbor. He is the land lord. Sudden in December The water stopped. When we called the water department he said the water bills are not being paid. We spoke to the landlord so he said due to increase in tax we have to pay 200rs extra. We even agreed for it but still the water was not started. Two days back my father And my neighbor went to tlk to him again so he Said that we wil have to pay 30000rs each . I am even ready to take a new connection of water line but I am sure that he won't giv me an NOC. For information the landlord want me to vacant the place since 10-15 yrs. Bt he is giving us less than half the value of d property n so we have denied him. Kindly advice what to do because it has been 20 days since no water.
