Rehabilitation drainage system Töbeli

As an implementation of a large GEP measure, the project "Rehabilitation of the Töbeli drainage system" was realized in Flawil with two stormwater tanks. The core element is the new construction of the Töbeli stormwater tank with a usable volume of 900 m3 and an adjoining control room. The inlet channel to the stormwater basin was designed as a two-level structure in order to re-route a section of the Dorfbach stream above the combined sewerage inflow from the sewerage network.
