An Idaho Wastewater Treatment plant was using sand beds at their plant. They were having problems dewatering their biosolids in the winter months. Clearwater Dewatering of Nampa, Idaho the local agent for WaterSolve LLC, worked with the city to solve their problem. The solids would be dewatered and then hauled to a landfill for final disposal by the city. The project was started in December 2007.
