The following are of private ownership:
(1) Continuous or intermittent waters rising on lands of private ownership, while running through the same;
(2) Lakes and lagoons, and their beds, formed by Nature on such lands;
(3) Subterranean waters found on the same;
(4) Rain waters falling on said lands, as long as they remain within the boundaries;
(5) The beds of flowing waters, continuous or intermittent, formed by rain water, and those of brooks, crossing lands which are not of public dominion.
In every drain or aqueduct, the water, bed, banks and floodgates shall be considered as an integral part of the land of building for which the waters are intended. The owners of lands, through which or along the boundaries of which the aqueduct passes, cannot claim ownership over it, or any right to the use of its bed or banks, unless the claim is based on titles of ownership specifying the right or ownership claimed.
