GeoTubes – Dewatering Lagoons

In Chesley, Ontario, Geotubes are being used to dewatering sewage lagoons. It is the first cleaning of the lagoons in 25 years and the first municipal use of geosynthetic dewatering tubes in the Grey-Bruce region. This simple process uses permeable geotextile bags that retain solids while usable lagoon water leaks back into the facility. The Geotube brand is manufactured by TenCate. The Chesley project uses 100-ft-long, 30-ft-circumference tubes capable of holding 38,000 litres. Dewatering is being conducted by Eganville-based Bishop Water Technologies Inc. Other nearby communities are considering the same lagoon cleanup plan.
