Leading the Nation in Horizontal Drilling Solutions Since 1996

Ellingson-DTD has been a leader in horizontal directional drilling (HDD) for environmental remediation across the United States for three decades. Our team specializes in designing and installing horizontal wells for some of the industry’s most complex challenges, including coal ash dewatering, groundwater control, and management.

Innovative Solutions for Safer, Faster CCR Dewatering

We pioneered and patented a horizontal methodology that allows utilities and engineers to dewater coal combustion residual (CCR) sites more effectively than traditional vertical wells. By combining custom-engineered tools, patented equipment, and a multidisciplinary team of geological engineers, environmental scientists, and drill crews, Ellingson-DTD delivers safer, faster, and more cost-efficient results.

A Trusted Partner in Coal Ash Management

When you work with Ellingson-DTD, you’re not just hiring drillers; you’re gaining a partner who understands the science and risks of coal ash management. We collaborate closely with consultants, owners, and regulatory partners to design wells that meet site-specific needs while protecting people and the environment.
