If you're trying to get a new water connection under the pagdi system, the BMC may put your application on hold if the landlord hasn't paid property tax. This is because property tax is essential, and the BMC is justified in demanding it before releasing an additional water supply connection. The best approach is to negotiate with your landlord to pay the arrears, possibly splitting the cost and deducting it from your rent, as legal action against the BMC is unlikely to be successful.
