Abstract
Regional business promotion has been considered by means of resource utilization of deep seawater (DSW) in particular attention to the cost of pumping facility of DSW.
Existing pumping facilities of DSW have been examined their design, construction and cost. Although there is a large scale merit of the pumping facilities in the construction cost, important thing is to chose a suitable maximum size of pumping capacity based upon possible utilization demand of DSW in the area. A business model for regional promotion according to the business scale is proposed under the consideration of construction and running cost of pumping facility.
Choosing a suitable scale for each region, DSW could be used as a resource to support the regional economy.
