PROBLEM TO BE SOLVED: To provide water intake and discharge equipment which discharges water, taken into a water intake channel from the outside, to the outside via a water discharge channel communicating with the water intake channel, and which rapidly damps surging even when an area of a free water surface of a surge tank is small. SOLUTION: In this water intake and discharge equipment 1, the water intake channel 2 takes the water from the sea, and leads the water to a water intake tank 3. The water of the water intake channel 2 is stored in the water intake tank 3. The surge tank ST is provided on the water intake channel 2 and the water intake tank 3, and the surging is damped by the free water surface. An intake pipe 4 leads the water to a condenser 5 from the water intake tank 3. The condenser 5 cools water vapor after work is taken out in a turbine etc. by cooling water of the intake pipe 4, and discharges the warmed water to a water discharge pipe 6. The water discharge pipe 6 leads the water to a water discharge tank 7 from the condenser 5. In the water discharge tank 7, the water for being discharged to the sea is stored. A water discharge channel 8 makes the water of the water discharge tank 7 flow out to the sea. A surplus water channel 9 communicates a predetermined height position of the surge tank ST with the water discharge tank 7, and discharges the water, running over the predetermined height position in the surge tank ST, into the water discharge tank 7.
