01What is being requested
The contract concerns the removal of exotic aquatic plants such as large bladderwort, water primrose, and water milfoil. The works will be carried out via sub-orders for periods of 4 weeks during a duration of 48 months.
Exotic aquatic plants have been increasingly present in ditches and waterways since approximately 2000. Due to their strong, invasive growth, they obstruct the flow of watercourses. Furthermore, their presence causes oxygen deficiency in the water and displaces other plants. As a result, they pose a threat to other aquatic life.
