Theresa Connor

Senior Environmental Engineer

Listening closely to ‘what is doable’ in the community is key to forward progress.

Theresa Connor, P.E., has spent over 35 years providing water, wastewater, and stormwater utility service to communities. She started as a survey assistant out of high school and later spent nearly 20 years in executive leadership of local utilities overseeing drinking water, wastewater, reclaimed water, stormwater, solid waste, and electric utility programs. She values the perspective of “boots on the ground” operators and other “on the ground” professionals who provide reliable, safe, and essential utility service to communities. Since joining ERG in 2022, Theresa has supported projects to assist wastewater and drinking water systems. For example, under the U.S. Environmental Protection Agency’s Closing America’s Wastewater Access Gap initiative, she provides communities that need reliable wastewater infrastructure with technical support to develop effective solutions.

Theresa has been involved with over a billion dollars of capital improvement programs and developed multiple master plans for fast-growing communities to keep pace with their water, wastewater, and stormwater infrastructure needs. She has been a champion of one water approaches to water challenges for 30 years and has been deeply involved in green infrastructure, water reuse, and integrated water solutions that benefit the natural systems and a community’s water needs.

Theresa holds an M.B.A. with a finance focus from Webster University, an M.S. and B.S. in environmental engineering from Iowa State University, and a B.A. in mathematics from Simpson College. She is a licensed Professional Engineer in Florida, Colorado, and New Mexico. Theresa lives in Fort Collins, Colorado, where you will most likely find her on a mountain trail, but you may find her in Iowa on her family’s farm or in Florida playing beach volleyball and kayaking the bays looking for ospreys and manatees.
