Water right
Résumé
Water right in water law is the right of a user to use water from a water source, e.g., a river, stream, pond or source of groundwater. In areas with plentiful water and few users, such systems are generally not complicated or contentious. In other areas, especially arid areas where irrigation is practiced, such systems are often the source of conflict, both legal and physical. Some systems treat surface water and ground water in the same manner, while others use different principles for each.
Water rights requires consideration of the context and origin of the right being discussed, or asserted. Traditionally, water rights refers to the utilization of water as an element supporting basic human needs like drinking or irrigation. Water rights could also include the physical occupancy of waterways for purposes of travel, commerce and recreational pursuits. The legal principles and doctrines that form the basis of each type of water rights are not interchangeable and vary according to local and national laws. Therefore, variations among countries and within national subdivisions exist in discussing and acknowledging these rights.
Often, water rights are based on ownership of the land upon which the water rests or flows. For example, under English common law, any rights asserted to "moveable and wandering" water must be based upon rights to the "permanent and immovable" land below.
On streams and rivers, these are referred to as riparian rights or littoral rights, which are protected by property law. Legal principles long recognized under riparian principles involve the right to remove the water - for drinking or irrigation - or to add more water into the channel - for drainage or effluence. Under riparian law, water rights are subject to the test of "reasonable use". The judiciary has defined "reasonable use" principle as follows: "the true test of the principle and extent of the use is whether it is to the injury of the other proprietors or not.
