What the buyer is looking for
The purpose of this purchase is to contract a contractor for the realization of a drainage, collection pipeline and discharge system in the Perkpolder area. With these measures, groundwater from the vicinity of the flood defence is collected in a controlled manner and discharged to the Westerschelde. The work contributes to the prevention of a possible negative impact on the ground and surface water quality in the hinterland as a result of possible leaching from the thermally cleaned soil applied in the flood defence (TGG). See the already filled in field regarding short description.
