Issue

Insufficient water quality

The quality of the water is insufficient.

The water in the lakes near Loosdrecht contains a lot of peat sludge. This causes problems for sunlight to penetrate into the water, which has a negative influence to the water quality. The redundant sludge is being removed from the water by dredging activities. Besides that, the peat fields in the area require maintenance.

Solution

Peat field restoration by using local sludge

A new technique is used which combines peat field restoration with dredging activities. The redundant sludge from the lakes in the area is being used to restore the peat fields. By doing this, two problems are being solved simultaneously.

Pros

  • Sludge from dredging activities can be used instantly and does not have to be processed further. This causes a reduction in CO2 emission.
  • The peat fields are restored by using only naturally degradable materials.
  • The reed banks provide the peat fields with a natural appearance.
