What the buyer is looking for
This contract is part of the tasks assigned to the Blue Mesh Department, relating to the maintenance, ecological management and enhancement of ponds located in the Brussels-Capital Region. More specifically, it aims to carry out bathymetric surveys of regional ponds. These services are essential in order to have objective and up-to-date data on the morphological status of water bodies, in particular as regards the level of siltation. This information is an essential technical prerequisite for assessing the ecological status of ponds and for defining, planning and prioritising appropriate management measures, such as clean-up, ecological restoration or adaptation of management methods.
