Wichita State audits Augusta's wastewater treatment plant for energy savings and cybersecurity

In the heart of Augusta, Kansas, city officials gathered at the City Council meeting on May 5 to discuss a significant collaboration aimed at enhancing the efficiency of the local wastewater treatment facility. The meeting highlighted a comprehensive energy audit conducted by a team from Wichita State University, which promises to bring both environmental and economic benefits to the community.

As the presentation unfolded, attendees were introduced to key terms essential for understanding the wastewater treatment process. The team explained concepts such as influent and effluent flow, measured in million gallons per day (MGD), and the importance of energy consumption in the facility's operations. The audit's primary goal is to assess energy usage and explore renewable energy options while ensuring cybersecurity measures are in place.

The audit revealed intriguing insights into the facility's operations. Data analysis from 2022 to 2024 indicated that energy usage did not directly correlate with effluent flow, suggesting that other factors, such as microbial activity in the oxidation ditch, play a significant role. Notably, an E. coli outbreak in 2022 led to increased energy demands, prompting the team to investigate potential areas for energy savings.

Three key areas were identified for improvement: the oxidation ditch, influent pump station, and UV disinfection system. The oxidation ditch, where biological processes break down waste, was highlighted for its energy-intensive mixing operations. The team emphasized the need to optimize these processes to align energy consumption with the actual needs of the microorganisms responsible for waste breakdown.

Throughout the presentation, the collaborative spirit between the city and the university was evident. Shane Noland, the facility's operator, was praised for his exceptional management, which made the audit team's task more challenging yet rewarding. The findings from this audit not only aim to enhance the facility's efficiency but also reflect a broader commitment to sustainability and responsible resource management in Augusta.

As the meeting concluded, city officials and residents alike were left with a sense of optimism. The ongoing partnership between Augusta and Wichita State University signifies a proactive approach to addressing environmental challenges while fostering community well-being. With the final report on the energy audit nearing completion, Augusta is poised to take significant strides toward a more sustainable future.
