Construction was recently completed for a new nitrification recirculation pump station for the City of Reno which incorporated a new 400 amp Motor Control Center (MCC) to provide extra capacity for future HVAC and other equipment. This important electrical upgrade to the Truckee Meadows Water Reclamation Facility was designed by Dinter Engineering, working as the City’s Prime Electrical Engineer for both design and construction support services. Dinter provided the MCC with power and controls to the main submersible pumps used to wash and flood the wastewater tanks.
This pump station uses nitrification to convert ammonia from the organic wastes in the waste water to nitrates that can then be safely flushed back into the water without harming downstream ecosystems and aquatic life. Adhering to strict guidelines and timeframes in both design and construction efforts avoided disrupting the important nitrification treatment process.
Dinter’s design included replacing two new Variable Frequency Drives for the pumps, adding a new speed signal for the pump and two new 100 HP submersible pumps for nitrification recirculation, while providing additional power meter monitoring back to the bleach building and adding spray bars and spray valves. Dinter also provided arc flash calculations and labels for the new equipment and a phasing concept to ensure the system can be operational when needed.
