Marler Flood Project Reaches Key Milestone as Climate Risks Mount, June 01

The Lippeverband met in Essen this week to review the HaLiMa flood-control project in Marler and Haltern-Lippramsdorf. Rising extreme weather events are driving the need for stronger flood defenses. The dike rebuild serves both safety and nature protection, with the next major milestone expected in 2026.

Why Flood Protection Matters Now

Michael Kalthoff linked the project directly to worsening weather patterns. Rising numbers of extreme weather events are making flood protection more important for residents along the Lippe. The river now carries more water more often, forcing engineers to balance flood safety with ecological needs.

Scale of Investment and Progress

The Lippeverband is planning annual investments averaging 150 million euros across the Lippe region. By the end of 2025, the Nordaue section had completed 3.7 kilometers of dikes and created a 42-hectare floodplain area. The new dike paths are now open to the public, turning a civil engineering project into a visible community asset.

The project aims to deliver around three million cubic meters of additional retention volume. The Südaue section remains under construction, with a new dike body being built over around 500 meters and another 18 hectares of floodplain area being created.

Blending Infrastructure with Nature

The HaLiMa project fits into the Lippeverband’s broader strategy for a blaugrüne Zukunft in the Lippe region. The program Lebendige Lippe, funded by North Rhine-Westphalia, aims to give the river significantly more room by moving dikes farther inland. This approach protects communities while restoring natural floodplain habitat.

Final Thoughts

The Marler flood project represents a shift toward combining climate resilience with environmental restoration. With 150 million euros in annual investment and visible progress in dike construction, the Lippeverband is building infrastructure that serves both human safety and ecological recovery.
