During a violent wind storm accompanied by heavy rains, the production site of a power plant was hit by an 80 cm water wave.
Administrative buildings, workshops, company canteens and the cooling water pumping system were all flooded. A part of the pit housing the pipes was submerged and the drip collection tank overflowed due to excess water. According to the operator, 90,000 m³ of water was pumped out and emptied into the Gironde river. The water that seeped into the underground tunnels led to the failure of equipment and circuits vital for safety (total failure of the emergency injection pump and enclosure sprinkler pump and partial failure of the emergency raw water pump).
