City Council Utility Committee <br />Meeting Minutes <br />Friday, June 22, 2018 <br />Page 3 of 7 <br />plant equipment. Mr. Kowar stated we have a lot of grass to mow as the Reuse <br />ponds are now filled in. Councilmember Stolzmann asked if it would be better to <br />contract this service versus buy the equipment. Mr. Kowar explained each facility <br />needs their own equipment. Mr. Kowar said this project was vetted and was the <br />preferred approach. Additional information on the alternative analysis will be <br />provided prior to the July 12th Council Budget discussion. <br />Drum Thickener <br />Mr. Kowar described this as a critical piece of equipment within the wastewater <br />treatment process. It is an older unit and we are being proactively replacing this <br />one as it has long lead times. <br />Dewatering <br />Mr. Kowar explained this is another replacement that is needed as it's an older <br />unit and has a long lead time as well. <br />Influent Pump <br />Mr. Kowar explained this is the addition of a sixth pump at the influent pump <br />station. This replacement is needed to provide faster recovery and more <br />redundancy at this location. Councilmember Stolzmann asked about the Lift <br />Stations. Mr. Kowar stated that the City has three operational lift stations: Steel <br />Ranch, North End and CTC. Storage Tech is private and not active. Mr. Kowar <br />went on to discuss the recent problems at the Steel Ranch Lift Station and what <br />was required to get it up and running. <br />Probes <br />Mr. Peterson explained how the installation of new probes will allow for better <br />real time information coming back to the system leading to the optimization of the <br />process. Mr. Kowar highlighted his recent tour of the wastewater plant and <br />discussed the automation process. Staff continue to optimize and get more <br />sophisticated in the operations. As an example the wastewater plant is running <br />off MCRT that is providing higher accuracies. <br />A -Basin Mixer <br />Mr. Kowar described the issue of a buildup of a grease layer in the first chamber <br />of the aeration basin prior to be being distributed to any of the three basins. The <br />goal of this project will be to breakup this grease by the addition of new mixers. <br />Vibration and Monitoring <br />Mr. Peterson describes the addition of new monitoring equipment on the various <br />pumps that will provide direct feedback on the pump performance in comparison <br />to their tolerances. This real time data can be tracked within the SCADA System <br />allowing for better asset control. The monitoring also provides a greater level of <br />sensitivity beyond a typical visual inspection improving the timeliness of detection <br />and the subsequent maintenance and repair response. <br />Lights <br />Councilmember Stolzmann asked if we can do this for less and Councilmember <br />Keany asked if there are lights out there now. Mr. Peterson answered the <br />5 <br />
