 each landowner is expected to protect his or her own land from surface and runoff water. ... If surface water runs from your neighbor's land onto your land, causing more damage than natural, you are still expected to protect your land from this water.

If your neighbor acts unreasonably or carelessly with water on his own property in a way that causes water damage to your property, you can sue for compensation for your losses and also ask the court to order the neighbor to stop the action

The civil law rule, also known as the Natural Flow Rule, imposes liability on any landowner that changes his or her land in a way that changes the natural flow of surface water across the land.

You may consult a local advocate on this and initiate legal action as per law if the tortures do not stop.
