Abstract
The seawater pumped- storage pilot plant (maximum output 30MW) was recently completed in Okinawa Prefecture, Japan. The site is located in the northern part of Okinawa Main Island, where the rich environment still remains. Many valuable, even endangered species are also found on and nearby the plant site. However, the land is covered with thick layer of red soil making a serious impact on the coral reefs when discharged. The point of environmental conservation measures was, therefore, that both the protection of valuable species and the prevention of sediment yield of red soil should be taken into great account during the plant construction and after its completion as well.As for the actual countermeasures, small plastic fences and trapezoid-shaped gutters were installed around the construction site so that small animals could not intrude into the site and could easily bail out when trapped in the gutters. Sediment yield was also effectively reduced throuh catch drains, weirs, and sedimentation ponds. Environmental monitoring was carried out over the construction period. The plant site was fully restored to the native condition after its completion.
