Small scale sediment management solutions

Important results from the project

The project has, from interviews and workshop mapped common handling of stormwater sediments and important needs of stakeholders like Trafikverket, VA-principals and material terminals. The project has customized the it´s solutions after these requirements. The market requests better understanding of how to control and follow-up stormwater dam´s sedimentation situation. This input is needed in order to adjust dredging and dewatering activities and to landfill/reuse dredged sediment. Work is in progress to include Trafikverket and several municipalities to the project.

Expected long term effects

The project has combined developing technologies on three critical points in the management of stormwater sediments: classification, dredging/dewatering and treatment. The project group has handling concept that will be tested and further developed in full scale. Real-time and/or mobile field monitoring combined with technique for sediment dredging and dewatering and also drainage and treatment is estimated to be adjusted after needs. The objective is that together with end users accomplish a number of field trials and show the ability to reduce cost and environmental impact.

Approach and implementation

The project group´s experience from different areas of expertise such as on handling of sediment, stormwater and dewatering, and its large network were important components in the project. This has helped to sharpen the basic ideas and to recruit new actors and end users. The workshop that was organized in the project was fundamental to identifying knowledge needs and to lift the end user´s perspectives and demands. There is work in progress to involve Trafikverket and several municipalities to the project.
