Rigofill®ST is a solution for the retention or infiltration of underground rainwater. The water is intercepted in the modules before being gradually returned, in nature or in the network. In addition to or as a replacement for alternative conventional infiltration techniques such as drainage networks, gravel or valleys, Rigofill®ST offers a fully modular system with a perfectly optimized storage / infiltration volume.
The useful volume optimization ratio ranges from one to three compared to gravel ponds for example, which considerably saves space and excavation operations. The modularity and ease of installation of Rigofill®STs have many advantages, both for the client and the installer.
