Whenever the yard or court of a house is surrounded by other houses, and it is not possible to give an outlet through the house itself to the rain water collected thereon, the establishment of an easement of drainage can be demanded, giving an outlet to the water at the point of the contiguous lands or tenements where its egress may be easiest, and establishing a conduit for the drainage in such manner as to cause the least damage to the servient estate, after payment of the property indemnity.
