The purpose of this study is designing of the Water-Pot which made of Porous Concrete (POC) for Graywater Purification. By the water plants are set with Water-Pot POC, the graywater is purified and the life environment is kept clean. At first, to find the ability of POC, some experiments were implemented. As a result, the following effects were obtained : 1)POC have some abilities of graywater purification polluted by organic, nitrogen compound, phosphorus compound and so on. 2)Water life, they can purify graywater, were identified on the surface of POC. And the more high ability were expected in the warm days. 3) Water changes alkarine water when POC is set. The best method of protection is the coating with polyurethane if we want the highest efficient, with lye remover if we want the highest economy.
