Our flexible sediment management comprises three important areas of work:
Maintenance: This includes the maintenance and upkeep of waterways and harbor basins by continuously surveying the bottom of the waterway, sampling and analyzing the sediment, dredging and transporting the excess sediment as well as the environmentally friendly removal of the sediment. The excess dredged material is relocated to suitable places in the watercourse or taken ashore for treatment and disposal.</p
<p>Remediation: In order to further improve the sediment quality and thus expand the possibilities for resource-conserving handling of dredged material, we are committed to remediating the sources of pollution on the upper Elbe. At the same time, we have been relieving the Elbe and North Sea of large quantities of pollutants, most of which do not originate in Hamburg, for almost 30 years through our removal, treatment and disposal of contaminated used sediments on land.
<p
<p>Current engineering: Current-influencing, current engineering measures such as the creation of shallow water areas are suitable for reducing sedimentation in principle. The approximately 30-hectare shallow water area Kreetsand has now been completed. It is a new, natural flooding area that is intended to reduce the accumulation of sediment in Hamburg's port area to a certain extent.</p
<p>Our overall strategy shows how all three areas of work interact and what else is needed to keep the port permanently at depth.
