Modifying structures for fish migration (Construction Team Agreement)
Waterschap Brabantse Delta intends to modify seven structures (weirs, pumping stations, and other water-regulating constructions) in an open procedure to promote the migration of various fish species. The works are aimed at creating fish-migratory passages, allowing fish to move freely between spawning, nursery, foraging, and overwintering areas. The modifications must maintain water level regulation, comply with environmental and safety standards, and be technically feasible within the existing infrastructure. The assignment falls under the works category, using a construction team agreement as the contract form. The contracting authority expects a transparent, open procurement process with clear specifications and a realistic schedule. The works are essential for preserving biodiversity and the ecological health of the delta area.

Waterschap Brabantse Delta installed weirs and pumping stations to regulate water levels. However, weirs, pumping stations, and other structures impede fish migration. As a result, fish cannot move freely. Resolving fish migration bottlenecks is important. Various fish species swim between (parts of) waters to be able to reproduce successfully. Migration is therefore a necessity for the survival of these species. We define the term fish migration as the movement of fish between spawning, nursery, foraging, and overwintering areas. The water authority intends to make a total of 7 structures fis
