RigolenSysteme

RigolenSysteme refers to a family of modular drainage and infiltration solutions that use underground trenches filled with porous media to manage water and improve groundwater recharge. The term is commonly used in German-speaking regions and other parts of Europe to describe engineered systems that emulate natural infiltration processes while providing controlled drainage for stormwater, wastewater effluent, or agricultural drainage.

Design and components

RigolenSysteme typically consist of a trench or chamber within a porous backfill, sometimes paired with perforated pipes, geotextile fabrics, and a surface cover. Inlets collect water from roofs, pavements, or drainage networks, which then percolates through the filter media before entering the soil. Sizing depends on site conditions, including rainfall intensity or effluent volume, soil hydraulic conductivity, and desired residence or recharge time. The systems aim to minimize sediment transport and protect groundwater by using filtration layers and appropriate backfill materials.

Applications

Common applications include decentralized stormwater management, urban and rural infiltration wells, and agricultural drainage improvements. They are used to reduce surface runoff, promote groundwater recharge, and provide a decentralized alternative to surface detention basins or centralized treatment facilities. RigolenSysteme can be integrated with existing drainage networks or used in new developments where space is limited or where permeable landscaping is prioritized.

Maintenance and performance

Performance hinges on proper design, installation, and ongoing maintenance. Regular inspection, sediment and clogging control, and filter replacement or cleaning are essential to prevent reduced infiltration capacity. Local regulations and environmental standards govern materials, installation, and monitoring requirements.

History and context

RigolenSysteme emerged in the context of sustainable drainage and low-impact development, reflecting a shift toward infiltrative, nature-based approaches in European civil engineering. They continue to be refined through research and practice to balance efficiency, cost, and ecological impact.
