Mixed water basin in Kirchgarten, Laufen
In the context of the General Drainage Plan (GDP) of the wastewater association for the Laufental-Lüsseltal region, HOLINGER is constructing a mixed water basin in the parish garden of the Herz-Jesu church in Laufen. The retention basin will only be used for wastewater in overflow situations. As soon as the basin is full, excess water will be released into the Birs river via the discharge structure and the newly constructed clean water pipe. The amount of wastewater that is passed on to the Zwingen wastewater treatment plant can be regulated by discharge measurements.
