Basic Wastewater Operations

Basic Wastewater Operations

About the Program

Wastewater treatment facilities throughout the United States must achieve water quality standards with the best management practices available for handling wastewater flows from residential, commercial and industrial establishments. Wastewater operators play an essential role to make water safe for beneficial purposes through a series of treatment processes and water reclamation stages in human and environmental health. HCC’s Industrial Technology and Energy Wastewater Operations program prepares students for standard procedures and other techniques used to manage equipment as well as other sections of the Wastewater treatment system. The program helps students fulfill industry requirements, including the Class D licensing requirement by the Texas Commission of Environmental Quality (TCEQ). An individual holding a Class D license can work in the public works department of a municipality and companies in the private sector.
