Butler Water Reclamation Facility
Design Consultants:Architect/Engineer-Black & Veatch
The significant cost escalation resulting from skyrocketing material costs and labor shortages resulted in a cost estimate that far exceeded the original project budget. In response, the project team created several design alternatives that could be constructed as a single project with minor adjustments to the program budget.
The team committed to work together to meet the 24 month construction schedule and a Guaranteed Maximum Price based upon treatment plant drawings that were 60% complete and only schematic design of the pipeline and pump station.
When completed, this was the largest capital project in the City of Peoria's history. It was also the largest Membrane Bioreactor (MBR) facility in North America when it was commissioned. The 10 million gallons per day (MGD) facility is expandable to 13 MGD. Flows are delivered via a 25 MGD peak capacity remote pump station that has rough screening capabilities. The new plant features fine screens, nitrogen control, and UV disinfection. Solids are dewatered with three 275 GPM centrifuges. A screw conveyor system conveys dewatered solids to truck containers that haul the waste to a landfill. The dewatering process layout was sited to allow for a future addition of high-level solids treatment to achieve a Class A biosolids suitable for reuse.
The Influent Pump Station (IPS) is located offsite in a prime commercial area that was undergoing concurrent development of high-end retail shops, restaurants and entertainment venues. The adjacent intersection had suffered from odor problems in the past, and one of the primary considerations for the operation of the IPS was that it prevent inherent odors from impacting the adjacent development, as well as to structurally blend aesthetically with the neighborhood. The solution to this problem was to construct the facility with a focus on architectural continuity and the inclusion of a low-profile odor control system.
The project also included approximately 44,000 linear feet of off-site piping that connected the IPS, water reclamation plant and a regional groundwater recharge faciltliy. Installation of the piplines was coordinated with traffic and public access along many city streets including jack and bore crossings of one state highway, one waterway and one city roadway.
