Gresham, Smith and Partners announces that Senior Water Resources Engineer Mike Burgett, P.E., and Water Resources Engineer Amanda Dobbs, P.E., will present at the Tennessee Association of Utility Districts Business Conference on Aug. 9 in Gatlinburg, Tenn. Through a case study on GS&P’s work to rehabilitate the City of Springfield’s sewers, the duo will highlight smart strategies for wastewater management.

“By developing a system-specific approach for rehabilitating the City of Springfield’s wastewater infrastructure, we were able to reduce inflow by approximately 125 million gallons a year, maximize storage and improve capacity—ultimately setting the stage for long-term success,” commented Burgett. “We look forward to sharing the lessons we learned with attendees at the Tennessee Association of Utility Districts Business Conference.”

A summary of the presentation follows.

Sewer System Rehabilitation: Lessons Learned to Improve Construction Quality
Presentation by Mike Burgett, P.E., and Amanda Dobbs, P.E.

Like many cities both large and small, the City of Springfield, Tennessee’s sewer system is aging and in need of repair. In September 2012, the City received an Administrative Order on Consent (AOC) from the United States Environmental Protection Agency, which required the City to ultimately eliminate sanitary sewer overflows. The City called on GS&P to develop and manage the City’s Overflow Abatement Program and help the City comply with the AOC.

Since 2012, GS&P has assisted the City with seven sewer improvement projects to repair defective pipes and restore the collection system’s capacity. Using cured-in-place (CIPP) lining and pipe bursting methods, the team rehabilitated approximately 35 miles of sewer. By the end of the program, it is anticipated that approximately 100 overflows per year will be prevented within the city. This presentation will focus on best practices and lessons learned to improve construction quality during sewer rehabilitation.
