Evaluating alternatives to improve plant operations
Garver performed a comprehensive audit and evaluated ways to improve the Bentonville Wastewater Treatment Plant's operations, comply with future potential permit requirements, and accommodate increasing flows. We identified alternatives to replace aged equipment, improve process control and performance, and reduce power costs. The audit provided ways to reduce current costs through operational efficiency and lessen future capital improvements by maximizing the plant's infrastructure. Garver recommended that the identified capital improvements be separated into three phases, beginning by optimizing the biological nutrient removal process, along with implementing automated controls and monitoring. The following two phases will be designed to provide long-range solutions to meet phosphorus limits, first at 5 MGD then followed by a 12 MGD build-out scenario.
