Wastewater from the paper mill’s process system was being stored and treated in an on-site impoundment that was nearing capacity. The earthen dikes, which had been constructed over soft soils, needed to be raised to both increase capacity and provide protection from flooding of nearby rivers and streams. Due to property constraints, a portion of the project required constructing the dike raise on the inboard side. Geogrids were used to provide slope stability for the areas where inboard construction was necessary. The project was completed in May 1994 and was placed in service.
