The design called for a large-scale changeover of the existing 0.50 WWTP, with insufficient capacity and aged equipment, to a modern, efficient 0.9 MGD biological phosphorus removal (BPR) type facility. The facility was designed so that future units could be added, up to a 3.6 MGD future treatment capacity.
It is rarely easy for municipalities to keep up with demand — cost being a primary concern along with the moving target of population. Add to that, ever-more-stringent environmental regulations and a sluggish economy and the result can be exactly what the city of Prairie Grove, Arkansas was facing.
Taking these factors into consideration, MWY not only designed an efficient, expandable new wastewater treatment facility, but guided the city through the maze of permitting, funding and public correspondence necessary to complete a project of great magnitude for that community.
