Trotter and Associates, Inc. (TAI) is collaborating with the City of Plano to assess the performance and capacity of their 2.44 MGD Biological Nutrient Removal Facility with aerobic digestion. As part of the evaluation, TAI addresses a key challenge: the City’s septic receiving station, which handles up to 10,000 gallons of septage per day during peak season.

The additional solids load affects the facility’s overall capacity, especially in the aerobic digester. Our team is performing influent sampling and utilizing BioWin modeling to gain a thorough understanding of the facility’s operational dynamics.

TAI is also developing an updated Basis of Design to reflect the impact of the septage receiving station, helping to determine the aerobic digester's remaining capacity. The result will guide recommendations for improvements to the solids handling system, ensuring long-term efficiency and performance, which is critical to infrastructure, and optimizing the wastewater treatment processes.
