Product: Geotube® Dewatering Technology
Application: Power & Utility
Location: North Carolina
A coal-fired utility wanted to increase the capacity of their existing ash lagoons with minimal investment.
Geotube® dewatering technology was implemented and provided the utility with two benefits. Not only did this allow for dewatering of the ash lagoons' material, but the filled Geotube® units were then used to build up the sides of the lagoons increasing the height of the containment structures for increased capacity of the ash ponds.
By using Geotube® dewatering technology, the solids increased from 22.5% to 66% in the first 30 days. The filled Geotube® containers were curved to fit the contours of the designated area [photo 2]. The resulting raised berms were credited with lengthening the lagoon life by at least two years.
