The Phengu Archipelago in the Taiwan Straits is composed of Pleistocene basalt with the accumulation of coral reefs without any significantly mountainous terrain on any of the islands. The fresh water supply on the islands is in dire need of help in every possible way. The proposed Paisha underground reservoir is one of the most effective measures which could cheaply and practically provide fresh water for the use of the islands. This paper presents the investigation and planning of the proposed Paisha underground reservoir, including hydrological, geological, and operational studies in conjunction with the future perspective of water resources on the islands. After the completion of all of the possible reservoirs on surface and underground, the only way to meet the water demand in the future will be sea water conversion with tidal energy development. A preliminary analysis of the potential tidal energy in the Penghu atoll is also presented.
