On Friday, September 15, twelve students from the Water Quality Engineering Laboratory spent six hours at the Springfield Regional Wastewater Treatment Facility conducting settling tests and performing calculations to evaluate the facility's clarifier (settling tank) capacity. The Springfield sewer collection system combines street drainage and domestic sewage so that flow through the treatment plant can increase by six-fold in a very short time period during rain events. Operators need to understand how their clarifiers will perform so that they can prevent solids from washing out of the plant to the Connecticut River during these high-flow events.
Two professional engineers from Woodard & Curran who specialize in wastewater treatment plant design and troubleshooting trained the group in how to perform the tests and analyze the results. Professors Brown and Dean Pines accompanied the group. Suez NA, operators of the plant, hosted the event.
