It's very important not only to improve the structural capacity against an earthquake but also to secure the drinking water to survive through the situation of interrupted public water supply system just after the big earthquake disaster. It's well known where the places for disaster refuge are but not so known where the strage waters are and whether the strage waters are enough for water demand under the earthquake disaster. In this study, mesh analysis was carried out that was focused on the drinking water demand and supply in the situation of interrupted public water supply system for Miyagi prefecture. Water demand was estimated by population and water supply was surveyed for emergent water supply facilities. As the results, it was clarified that there were many water-insufficient districts, and by analyzing from the viewpoint of water demand density; population density, there were several characteristics of water insufficiency and countermeasures for each of them. Besides, it was shown that analyzing method of this study was convinient for considering effectual measures.
