Inquiries about the tour can be sent to our volunteer symposium tour coordinator Bryan Sinkler.
Symposium attendees are invited to tour the Polk County Northeast Regional Water Reclamation Facility. The Northeast region wastewater treatment facility NER WWTF is the newest and largest regional plant currently in Polk County. The original plant was constructed in 2001 with a capacity of 2 mgd. In 2012 the facility was expanded to a 6 mgd facility with a build out capacity of 9 mgd. The facility is a state of the art BNR/Oxidation Ditch treatment facility consisting of the following: an influent lift station, a screening structure (with two mechanical perforated plate screens, one manual bar screen, one biological nutrient removal tank (with grit removal and flow equalization capability) of 3.5 million gallons, two oxidation ditch aeration basins, three clarifiers, a standby polymer feed system, four deep bed filters, six chlorine contact chambers, ten aerobic digesters, two screw presses, and a docking area for a mobile sludge centrifuge. Also included is a RAS/WAS pump station with three pumps and a blower building with five positive displacement blowers. This plant is operated to meet secondary treatment with high level disinfection and meets Class I reliability.
Tour attendees will have the opportunity to learn about the plant’s treatment process and its fully automated control system. Major pieces of equipment will be explained, and insight will be offered as to how the plant’s automated control system works. The tour will comprise of a walking tour where attendees will have the chance to “walk through the process.” In addition to walking through the plant, attendees will also have the opportunity to see the plant’s central control room and see how the operators use the plant’s SCADA system to remotely control the various parts of the plant. Hosted by the PCU’s Northeast Regional WWTF Supervisor, the tour will give symposium attendees a glimpse into the facility’s extensive instrumentation and SCADA control system which provides continuous monitoring of the plant processes and data collection to maintain compliance with regulatory agencies.
The plant has a fully automated control system consisting of redundant iFIX HMI servers with Historian and terminal server based clients communicating to distributed Siemens PLCs over a fiber optic Profibus DP network. Instrumentation and valve actuators at the plant are “smart” type having Profibus DP and PA communications back to the system PLCs to provide additional data to the control system. This facility also utilizes WiFi hotspots throughout the plant to provide operations staff access to the SCADA system while working out in the plant environment. Additionally, the facility has an integrated Electronic Security System allowing viewing of CCTV cameras and gate controls from the operations building. Other County systems can also be viewed from the operations building across the County Wide Area Network.
