Water can take its course
The preliminary final piece of the interior work was the attenuation of ‘duct 20’. That is what they called the deep drainage ditch that crossed the Dwingelderveld. The duct was dug during the land cultivation to dewater the agricultural area of the Noordenveld.
The drying out of the heather that was a result of this came to an end. The natural situation is restored; from now on the water finds its own winding way back through the trenches and the water level is rising.
There were two reasons why this attenuation was not scheduled until now. First, the topsoil had to be excavated and removed. And only after all the transports had taken place could the asphalt be removed. Otherwise, there was a risk that other activities, such as the construction of the bike path with platforms, would fall in the water.
Water measures preceded the attenuation of ‘duct 20’. All smaller canals in the Noordenveld closed. Inconspicuous dams were scattered over the heathland that are going to help the water find its way over the next few years. Much more noticeable are the triangular dams at the edges of the area. These ensure that extra water can be temporarily collected in the Dwingelderveld during periods of extreme precipitation.
