BACKGROUND: The city operates seven production wells to provide potable water to the community. Each year, the above-ground components are visually inspected. More thorough inspections are completed every 6-8 years. These inspections include pulling the pump from the well, opening the pump and testing the electrical components, televising the drop pipe and well bowl, and identifying necessary repairs. These repairs can range from routine pump maintenance, to well casing replacement, to full rehabilitation. Earlier this year, staff solicited quotes from Traut Companies and Bergerson Caswell to perform the initial inspection and televising of Well 5, which was built in 1988 and last rehabilitated in 2016. Bergerson Caswell was selected for the inspection and televising phase of the project. Based on their evaluation, they have provided a quote for recommended maintenance in the amount of $26,105. The scope of work includes: • Replacing 7 pieces of drop pipe • Replacing 14 line shaft bearings • Replacing head shaft • Rebuilding of the discharge head • Rebuilding of pump bowl assembly • Reconditioning motor and replacing oil • Epoxy coating on pipe • Shop labor Bergerson Caswell has been the contractor on previous well rehabilitation projects for the city and is familiar with the critical components of our water delivery system. Staff is recommending the execution of the city standard contract with Bergerson Caswell in the amount of $26,105 to complete the recommended maintenance on Well 5. FINANCIAL IMPACT: Money is budgeted every year for this type of annual well maintenance. The 2023 Water CIP includes $52,500 for this project (601-49400.00-55530.00 Infrastructure).

As requested we are supplying a quote to perform the requested repairs/reconditioning to well pump #5. This pump currently is due for maintenance and was Removed a couple of weeks ago, we have disassembled and inspected all of the components in this pump installation and recommend the following repairs be performed to the different components. Overall the pump and well are in fairly good condition the bottom depth was same as when we reconditioned it in 2016, so no additional fill has built up since the last inspection. The pump does show normal signs of wear such that the bearing have .015 wear and the impeller skirts are worn to .048, according to the manufacture these values would indicate replacing the all bearing and having the impellers machined and wear rings reinstalled. These two repairs will bring the pump bowl back to as new condition and continue to operate as efficiently as designed. The other recommended repairs are the normal bearing replacement in the spider assemblies, straightening the line shafts, and reconditioning the discharge head packing gland, and replacing 65’ of column pipe. There are 75’ of pipe that we are reusing but 55’ is pipe that is above the SWL. The well was tested and video investigated, and everything appears normal I have included the results from the performance test, the installation data sheet, as well as the video investigation report along with this write up. One item I am not 100% sure about is epoxy coating. The last inspection we epoxy coated your pipe in anticipation that it would last through two maintenance cycles, but as it stands we are still replacing 65’. Now the epoxy coating has held up on all the pipe but the one we recommending replacing are corroded and the sealing surfaces (end of pipe with no epoxy)is where it is bad. The remaining areas of the pipe is still full thickness and in decent shape. I have offered a price for the epoxy coating the replaced pipe, and to rough up the surface on the ones that would get reused and recoat them $300/ 10’ section new and $120/ 10’ on the reused. I have included this below.
