Estimating the cost of product water conveyance from desalination plants

Methods are presented for estimating the costs of transporting, by pipeline, product water from desalination plants. Cost curves are presented for conveying from 19 to 380 x 10/sup 3/ m/sup 3//day (5 to 100 Mgd) to distances to 80 km (50 mile). Sand is used as the reference soil, and adjustment factors are given for earth, shale, hard rock, and swampland. Costs are given as a function of distance and include pipeline construction, pumping stations, power lines, and electrical switchgear.
