Pilot study pore water extraction
Indiana Pilot study pore water extraction 2022
Ellingson-DTD installed one coal ash dewatering drain within a partially capped and closed mixed ash basin. The HDD was initiated alongside the target basin from the bottom of an excavated adjacent basin. The bore penetrated the target basin wall and trended along the bottom of the unlined basin at an upward 0.5% before terminating at the far edge of the basin.
The drilling returns indicated the bore penetrated clay and then a mix of fly ash and other coal ash residuals. The drain totaled 1,081’ in length and included 936’ of 4” diameter schedule 80 PVC screen.
Upon completion, the well passively discharged 10-20 gpm, and 5 months after installation and intermittent pumping, the drain is still producing 15 gpm.
The Leader in Horizontal Coal Ash Dewatering
Managing groundwater and pore water doesn’t have to mean endless wells, pumps, and costs. Ellingson’s patented horizontal drilling method makes dewatering faster, safer, and more affordable-helping utilities, engineers, and contractors move ash from wet storage to compliant dry landfills with confidence.
With over 30 years of HDD expertise and more than 63,000 feet of coal ash wells installed, we deliver proven results that simplify compliance and protect communities.
If you’re ready for a more innovative approach to coal ash dewatering, Ellingson is the partner who can get it done.
