South Carolina Public Service Authority (Santee Cooper) has selected Stantec, a global leader in sustainable design and engineering, as its engineer to design wastewater treatment systems at two of the state’s power generation facilities. Santee Cooper is South Carolina’s public power and water utility.

Water treated through these best available technology treatment systems, as defined by the U.S. Environmental Protection Agency (EPA), will ensure Santee Cooper is meeting the EPA’s Effluent Limitations Guideline (ELGs). Addressing wastewater is increasingly important for municipalities and utilities as the EPA evolves its guidance.

“This project will play a vital role in treating wastewater at these facilities and make certain that what goes back into the local environment is in compliance with the EPA’s regulations,” said Jim Stone, Stantec project manager. “This effort is an extremely positive development for the community and the surrounding ecosystems.”

This award expands on a previous contract with Santee Cooper. In 2021, Stantec began work on one power generation facility and was recently awarded a second site to install similar technology, doubling Stantec’s scope of work. The Stantec project team will provide process, mechanical, electrical, controls, civil, and structural engineering; design; 3D modeling; and drafting to develop a holistic approach to install the wastewater treatment technology. 

EPA’s rules on ELGs are national wastewater discharge standards that apply to industrial and commercial facilities. They are a part of the Clean Water Act established in 1972 to regulate the discharge of pollutants into the environment.

The Stantec team has deep expertise in industrial water projects and is well versed in designing practical, cost-effective approaches for project delivery success.
