Following the disastrous floods of 1953, the Deltaplan was realised in the Netherlands. The estuaries in South-West Netherlands were dammed and the dykes reinforced. The result was a higher water level in the river Lek, making it impossible to discharge the water at Kinderdijk. To be able to pump the water to a higher level, it was decided to replace the pumping stations dating from 1924 and 1953 with a more powerful station. This was taken into use in 1995 and is called the Overwaard pumping station or Ir. G.N. Kok/ Overwaard. It has a capacity of no less than 1,500,000 litres or 1,500 m³ per minute.
