To provide an intake facility which can be constructed at low cost without requiring a large scale apparatus and can efficiently collect shellfishes.

The intake facility 1 which introduces seawater from the sea and store the seawater, precipitate and accumulate shellfishes and the like in the seawater, and then suck the seawater by a circulating water pump to supply it for cooling a generating apparatus comprises an intake chamber 2 for introducing and storing seawater, and the circulating water pump 3 for sucking the seawater in the intake chamber 2 to supply it to a condenser and the like of the generating apparatus. A shellfish storage vessel 17 for storing shellfishes is installed in the bottom of an almost center of the intake chamber 2. A wide plate-shaped curtain wall 10 is installed on the base end side than the shellfish storage vessel 17 (at the almost center of a gradually expanding portion 7).
