Usually seawater intake problems and corrosion are the two primary causes in desalination plants. The water intake systems' design appears simple, but problems often develop in the operation.
    So considering the following factors when design is suggested:
    (a) Identification and evaluation of the effects of seabed conditions;
    (b) Discussion of the primary design features of the waves and currents;
    (c) Consider physical site characteristics, meteorological and oceanographic data;
    (d) Think over the effects of water depth and temperature on intake performance characteristics;
    (f) Analyses of specific of your require water velocity.
