Handpump on abadi land where i am constructing my house as well

If you are having a clear and marketable title to the property by the virtue of registered title document on your name then you can file a suit for mandatory injunction against the authorities concerned praying for direction to remove the hand pump from your property.

Whether the handpump is installed by authorities or it is a private pump ?

Yes the Handpump was installed by authority, under the then Sarpanch. It isn't private.

Do you have a registered document to prove your title to the abadi land on your name.

The abadi land was allotted to your grandfather and subsequently it devolved on the legal heirs of the next generation.  Now you say that it has been allotted to you by your brothers, if so whether they had any authority to give this property to you, if so did they execute any registered release deed in your name.

Thus if you have a registered document in your favor to establish that this property belongs to you, you can file a suit for mandatory injunction against the local civic body to remove the hand pump of the borewell underneath the hand pump and also to close the said borewell. 

First of all establish your rights and then fight for your further rights in this connection.

Sure I am working on the legal documents through the regional Lekhpal and will file the suite accordingly but in case it happens that the handpump stops working, since it already is not working properly, before my case is resolved then would the authorities remove it or no action would be taken until and unless a final judgment is passed?

This is not your property and it is a government property and causing a hindrance or obstruction to you.

But you cannot remove or uninstall it.

You can be booked under theft offence if you are removing the government property on your own.

Therefore you may better follow the due process of law.

No I won't ever remove it on my own and will follow the due process of law only.

Thank you for your suggestions and comments.
