Danny O’Connell

Senior Compliance Specialist

The operation and maintenance of water and wastewater utilities requires a clear understanding of diverse variables unique to each facility. I enjoy evaluating these variables and creating conditions or systems that enable water treatment and management systems to perform at their highest efficiencies.


Danny O’Connell has over 30 years’ experience in water and wastewater utility compliance and industrial pretreatment programs, including design, development, implementation, administration, and evaluation. Over the course of his career, he has worked for consulting engineers, the City of Houston’s Wastewater Division, the Texas Department of Water Resources, the Massachusetts Water Resources Authority, an international private water/wastewater company, United Water, and (as a consultant) the U.S. Environmental Protection Agency and Department of Justice.

He has evaluated the operation and maintenance of over one hundred POTW collection and treatment systems, and monitored compliance of hundreds of POTWs and their industrial users. He has conducted many sanitary surveys and water system evaluations in the western United States and Guam. He has supported the development and implementation of water-related environmental programs across the nation. This work has included development of standard operating procedures; monitoring of industrial wastewaters; site inspections; data tracking and analysis; estimating wastewater treatment capital, operation, and maintenance costs; assessment of best management practices and pollution prevention approaches and technologies; and development and delivery of training programs. At PG Environmental (part of the ERG Group), he manages NPDES compliance work.

Danny is a certified water (distribution and treatment) and wastewater (collections and treatment) operator; a California-certified Environmental Compliance Inspector; and an EPA-credentialed Clean Water Act and Safe Drinking Water Act Inspector. He holds a B.S. in biology from Bowling Green State University.
