Lake Gallträsk, situated 15km west of Helsinki, used to be a popular recreational area with beaches and clear water. Unfortunately, it has suffered from major strain caused by habitation and industry. The lake is now being cleaned with a dredging program that it is utilizing Geotubes from TenCate. Roughly 26,000 m3 of silt will be removed from a 2 hectare area and pumped into a network of 12 Geotubes. To date, the lake’s oxygen level is responding very favorably to the treatment.
