Water disconnection for non payment of maintenance

I am a tenant in vashi navi Mumbai living in a rented apartment my room owner has not paid building maintenance for past 1 and half year due to a dispute wherein the society repair work Was done to overhead water tank and new pipeline was fitted wherein they had to break the terrace which my room owner had waterproofed a month back society at that point and time had assured that once the desired work is finished the terrace would be rebuilt properly but nothing as such was done and since the property is on top floor below the tank pipeline gets over flooded due to leakage in tank mechanism. My room owner had asked compensation from society regarding the same but none of it was given now the old committee has changed and they are trying to recover the dues and have sent a letter stating that water supply would be disconnected. My room owner is not ready to pay the dues since society never did any repair work (till then my room owner has paid regular dues) and my room owner had to shell out money to get the terrace fixed which actually costed more than the pending dues so he is not ready to pay it till the society comes for a settlement. Since I am a tenant I am worried about water disconnection and to shift my house I need to get my deposit back for which I have to give a month notice period as per rent agreement. I m stuck Pease advise the society is not registered. Kindly advise.
