Our water bottom in a broader perspective

Our water bottom in a broader perspective

The implementation of the Dutch Water Act (the Waterwet) provides a new field of influence over tasks and responsibilities for water bottoms focused around the district water boards and the Ministry of Infrastructure and the Environment. This change is having an impact on existing policy but also requires new policy. Antea Group supports organizations in this change process with knowledge and experience in shaping and implementing new policy.

Business Lines:

Design, installation, monitoring and management of storage sites for dredging material

For temporary and long-term storage of dredging spoil on land, Antea Group designs storage sites for everything from uncontaminated silt to unusable silt. Factors at play here include water removal, soil protection (whether or not a subseal is present), grounds development and landscape integration. In addition to this, we map out the impact of the storage facility on the environment (soil, groundwater, air, noise).

Regeneration of natural areas, water quality improvement

Natural areas are often home to special flora and fauna. Several policy initiatives (Natura 2000, EHS, WFD) endorse regeneration of natural values and improvement of water quality. Antea Group maps out the sticking points and provides advice on suitable measures.

These projects typically involve several stakeholders. Communication between stakeholders and the environment is vital to the success of the project.  Antea Group's environment managers are always ready to advise and assist our consultants and clients.

Sustainable reuse of dredging spoil

Reuse of dredging spoil helps reduce consumption of primary raw materials. Antea Group analyses the possibilities and devises plans to maximize reuse of dredging spoil, whether contaminated or not. For instance: by immobilizing silt or incorporating it into infrastructure projects. One key component is an analysis of the players involved in the project and the environment and creating a base of support.
Through our contacts with both dredging spoil disposal specialists and infrastructure project developers, we bring parties together.

Drafting water bottom quality maps

As part of an environmental hygienic quality provision for a dredging spoil party, a water bottom quality map can be used as documentary evidence. Under certain location-specific policies (the Dutch Soil Quality Decree), a water bottom quality map is even a required document. Antea Group can map out the water bottom quality for you.
