- Industrial Wastewater Treatment Plant Evaluation
Burns & McDonnell provided front-end planning (FEP) services related to Industrial Wastewater Treatment Plant (IWTP) improvements. The Front-End Engineering Planning report recommended replacement of the existing IWTP with a new treatment plant having parallel treatment trains for process redundancy. Each train will have a capacity of 550 gallons per minute (gpm) for a total treatment capacity of 1100 gpm. Following the front-end planning effort, the improvements will be defined, designed and constructed.
The client operates a coal-fired power plant in Indiana. The Industrial Wastewater Treatment Plant (IWTP) treats both dry- and wet-weather flows from process areas within the MGS campus. Effluent from the IWTP is discharged through an NPDES outfall to a reservoir. The reservoir provides non-contact cooling water for the power station.
The IWTP was originally placed in operation in the early 1980s primarily to treat coal pile runoff and other plant wastewater. Burns & McDonnell prepared a capacity and condition assessment was prepared for the IWTP in 2009. A variety of deficiencies were identified. Infrastructure showed excessive signs of wear and equipment was nearing the end of its useful life. NPDES permit excursions during the past decade have been attributed to the poor condition of the IWTP. To treat the current wastewater quality and quantity and maintain compliance with applicable regulations, improvements to the IWTP were recommended by the client's staff and Burns & McDonnell.
