Patel, P.E., CFM, Director of Public Works SIGNATURE _________ _ APPROVED BY CITY ADMINISTRATOR: Michael L. Guttman SIGNATURE _________ _ ITEM SUMMARY: Well No. 12, located at 627 W Hawthorne Lane, is one of the five City-owned deep wells. The well assembly consists of a Goulds Pump and a Byron Jackson 300hp motor with a mechanical seal, set at a depth of approximately 915 feet. The well is rated to pump 1,000 gallons per minute (gpm). The well was constructed in 2012 and has not been serviced since its installation. Starting in 2023 the Well began exhibiting reduced gpm while pumping. In 2024 the well assembly was tested following a failure of the Well. The testing results indicated wear of the pump assembly of the well, causing reduced gpm, requiring it to be pulled for a repair. Staff believes the pump assembly is ready for a complete rebuild based on the current output of 750 gpm. Layne originally installed the well in 2012. Due to its familiarity with the equipment and its installation, staff solicited a proposal from the Layne Company to pull, inspect, and rehabilitate the well assembly. Layne's proposal includes a complete rebuild and rehabilitation of the existing well equipment, including a television survey of the well casing. This proposal also contains provisions for a new column pipe, cable, cleaning and re-coating of the existing column pipe, and overall inspection of all well components. The estimated total for these services is $339,935.00, which includes a factory exchange motor for $124,736.00 if needed. At this time, staff does not believe the motor will need to be replaced. Staff requests that the City Council authorize the Mayor to execute a professional services contract with Layne Company, for an amount not to exceed $339,935.00, for services necessary to remove, inspect, repair, re-install, test, and place the well assembly at Well Station No. 12. This is a budgeted item in FY 2025 in 06-34-47-4420. ACTIONS PROPOSED: Approve Resolution No. 25-R-0001 authorizing the Mayor to execute a contract with Layne Company for professional services related to the Well Station No. 12 Rehabilitation Project for an amount not to exceed $339,935.00.

The Well 12 pump has not been repaired since the Layne new install in October 2017. Your records indicate a slight drop in flow capacity recently. Due to the nature of the situation, an exact cost cannot be determined until the pump has been pulled and inspected. However, for budgetary purposes, we have developed the list below, which includes all items that we believe will be required, as well as some items that may be needed on this 300HP, Type H 2300 volt Byron Jackson submersible deep sandstone well pump. • Mobilization to the site, pull the pump, briefly inspect on-site and measure the total depth and static water level. • Disassemble, inspect & rebuilding of the Xylem /Goulds bronze bowl assembly. • Mobilize 8" column pipe to our yard; sandblasting for inspection; and remobilize back to site. • Possible 8" T&C pipe repairs and re-epoxy coating, inside and out. • Service the Byron Jackson motor - change oil, epoxy coat exterior, etc. • New materials contingencies. • Reinstallation of the pump, including a test of the well and pump. Layne is the Authorized Service Center for Flowserve/Byron Jackson in Northern Illinois. We utilize factory certified service technicians for this work and have an extensive inventory of Byron Jackson parts in our Aurora, IL facility. • WATER RESOURCES 721 W.

We would typically use a Large Pump Service rig, along with a Large Truck Crane, with combinations of 2-, 3-, & 4-man crews. The listing of the items for our T&M estimate is broken down as follows: • Mobilization, pulling, and brief inspection on the site with pump service $37,500.00 crew Hydro crane and crew to load and haul bowl, cable, motor, etc. to yard $4,400.00 • Disassemble, clean, & inspect all bronze bowl assembly $3,400.00 • Sandblast 8" pipe for inspection $2,550.00 • • Complete servicing of 300HP Type H Byron Jackson motor, by Byron $5,900.00 Jackson certified technician • Hypot check of cable, lump sum $1,300.00 • Television survey of well, lump sum $1,850.00 • Refurbish Pitless adapter spool $2,400.00 • Rebuild 11 Stage - 12CHC Xylem/Goulds bronze fitted bowl assembly, $15,850.00 if required. Miscellaneous materials, such as, sodium hypochlorite, HTH tablets, $2,500.00 • stainless steel banding and buckles, etc. • Mobilization of bowl, cable, and motor back to site and unload $4,400.00 Pump service crew for reinstallation of pump, testing, and demobilization $41,900.00 • • Power tong usage, per 8-hour shift- est. 6 at $475.00 $2,850.00 Byron Jackson flat cable assembly $10,556.00 • • 8" T&C replacement pipe contingency, 300ft.@ 68.00/ft $20,400.00 • New No. 2, 2.4kV jacketed power cable, 930 ft. @ $36.00/ft = $0.00 $33,480.00 - assume reusable • 2 - 8" surge control valves@ $1,274.00 ea . $2,548.00 20 - 8" API Pipe couplings @ $222.00 ea . $4,440.00 • 2 A GIRArTI1, COIIPUY ===== PDF PAGE 9 ===== [Extraction: embedded PDF text] City of West Chicago Rocky Horvath, Water Superintendent Well No. 12 Page 3 • Cutting & rethreading of an estimated 20 non-coupling pipe ends . $4,700.00 Mobilization of~. to & from our Aurora yard $4,400.00 • • Sandblasting & epoxy coating of the 8" pipe, inside & out - 915' @ $33,855.00 $37/ft. • 300HP Byron Jackson exchange motor, including freight and credit for 124,736.00 City's motor Miscellaneous Repairs Contingency $7,500.00 • TOT AL ESTIMATED COST $339,935.00 We assume the pump can be pulled in a normal fashion without the need for any fishing for its removal from the well. Once the pump has been removed, cleaned, & inspected, Layne would provide an updated repair cost estimate BEFORE proceeding with any repairs. Of course, if we encounter something needed that is out of the ordinary, we will include that in the updated estimate. This has been standard practice on the many repairs that Layne has performed for the City in the past. We have not included a contingency for sand bailing, since sand production from Well 12 has not been an issue. The time to execute this work, of course, depends upon what work is actually done. But if the motor is reusable and we are able to completely service it in our Aurora Service Center as part of this repair, we would estimate the following time frames: • Mobilize, pull & inspect. - 1+ weeks • Repairs - 6 to 8 weeks • Reinstallation and testing - 1-1 /2 weeks. Layne appreciates the opportunity to help the City with its water resource needs. If you have any questions, please do not hesitate to contact us.
