The purpose of this research is to develop the catchment lid of the precast concrete with the durability and the cost performance. At first, material characteristics of the concrete with which various short fiber was mixed were checked. An impact test of the catchment lid made with short fiber reinforced concrete was performed. It was showed that the concrete reinforced with short fiber increases in the strength to the impact. An experimental result of various short fiber reinforced concretes with the same aspect ratio was compared. The flexural toughness of the concrete mixed with polyvinyl alcohol fiber (PVA-fiber) was increased than others. Furthermore, a bending test of the catchment lid manufactured by PVA-fiber reinforced concrete was performed. It was indicated that this product is excellent in the building performance, the durability and the cost performance as a result of the experiment.
