**2.7 Planning the establishment of a seawater farm**

The most important factor required for the establishment of a seawater farm is that there is a source available, close to seawater and at a low cost. The cost of seawater supply is the largest investment in this type of project, and it exceeds the other factors such as irrigation method, quantity of water required, and agricultural practices required.

Usually, in the case of direct supply of seawater, it is a sea pier extending into the sea where pipes are drawn to fetch water by pumps. Irrigation channels must be constructed in the fields of the project, all of which affect the coast in terms of appearance and other uses of the coast. The movement of water and various marine organisms and the properties and effect of seawater on the rust of metals used in these marine environmental installations and the movement of waves, winds, and hurricanes are many difficult problems that must be considered and taken into account when designing. Solutions are usually expensive.

The alternative approach is indirect supply through wells to collect seawater, thus avoiding many of the above problems. Therefore, in the case of a groundwater reservoir, seawater wells are the best solution, but the limited capacity of the well may be a problem (many of these wells have been discovered despite their presence on the seashore in many studies). After a source of seawater is found, the next task is to connect the water to the root area, which can take many forms according to the irrigation method used. In the case of small spaces that can be used, simple irrigation method of watering where a system can be characterized by the rapid flow of water in open channels or light PVC pipes or plastic tubes can be folded. In the case of larger areas, the sprinklers can be used with either the axial or the lateral spray where the water is distributed homogenously on the ground even if the ground is not precisely leveled.
