Also known as a filter box or a dewatering container, dewatering boxes separate liquids from solids in water and wastewater. Dewatering boxes make materials easier to handle, transport and dispose of. You can use a dewatering box to reduce the volume and weight of materials being handled, lower transportation costs and minimize the environmental impact of waste disposal. Our Project Uptime article, Construction Dewatering Q&A with the Experts has more information on dewatering systems and methods.
