New Dutch Rainwater Approach: No Wet Feet, Lots Of Birds And A Beautiful View

peak water disposal system

Water Board let polder Haastrecht deflate again.

We saw it this summer in the Netherlands. The rainfall the last years is extraordinary. Climate is changing and the regular water systems can not always get rit of the rainwater. Therefore, the Netherlands use a relatively new weapon against water: the peak water disposal system.

Normally, when it rained around the village Haastrecht, the pumps around the village excessed the water to the nearby river Hollandsche IJssel. But problems arose when the water in the river reached the highest position. Streets and houses got flooded. Thanks to the peak water disposal system, problems are over.

 

This is how it works

Through a pumping station at the river the excess water is pumped through an underground pipe to a excavated pasture. Once the river regains the ability to work away the water naturally, a second pumping station pumps the green area dry. 70 thousand cubic meters of rainwater (about 30 Olympic swimming pools full) that would normally flow through the South Holland streets, can this way controlled be eliminated.

 

Spectacular nature

Flood was the main goal. But the Dutch Water Board wanted to give nature a chance. During the excavation of the pasture last winter, they therefore choose for a tripartite division of the grassland area into different heights. It looks nicer and attracts other flora and fauna. Birder Dorsman loves it.

Last year there were twenty, maybe thirty snipes here. Now he has counted more than two hundred. Spectacular! As if suddenly a bird magnet appeared in the grass. The appeal of the pasture is because of the 70 thousand cubic meters of water that the local authorities pump to the grassland since Monday morning. You didn’t see those stilts here last year. Now we don’t have to fear wet feet, have lots of birds and a beautiful view.
