Guttman COMMITTEE AGENDA DATE: April 6, 2023 COUNCIL AGENDA DATE: April 17, 2023 SIGNATURE. ITEM SUMMARY: Since 2020, the City has conducted leak detection surveys of the water distribution system. A leak detection survey is a physical evaluation of a water system to identify specific leaks in the water system. The survey is performed using non-invasive methods utilizing listening devices to find leaks in pipes or fittings within the water distribution system. To date, this program has been successful in reducing the City’s water loss, which is often referred to as non-revenue water because the water is produced but never reaches the end user. This might be due to leaks in aging watermain, metering inaccuracies, or unmetered consumption, such as water used from fire hydrants. After its first leak detection survey in 2020, the City significantly reduced its average daily water production. A total of 36 system leaks were found by the vendor and repaired by City staff, reducing water loss by approximately 350,000 gallons per day or 128 million gallons per year. Staff solicited proposals for the 2023 leak survey. The scope of work includes surveying approximately 147 miles of watermain, using acoustic leak detection equipment to identify and pinpoint water leaks in metallic and non- metallic watermain pipe in the City’s entire water distribution system. All leak locations will be recorded using the GPS and will be transferred to City’s mapping system for future capital improvement planning. Three proposals were received. CONTRACTOR BID SUBMITTAL AMOUNT OVERALL RANK Consulting Engineering Inc. $26,349.75 1 ME Simpson $35,054.00 2 Associated Technical Services $36,210.24 3 Consulting Engineering, Inc. of Strongsville, Ohio, submitted the lowest responsible bid of $26,349.75. Reference checks were performed with favorable results. Therefore, it is staff's recommendation that a contract be awarded to Consulting Engineering, Inc. of Strongsville, Ohio, for the 2023 water system leak survey, in an amount not to exceed $26,349.75. Associated Technical Services (ATS) has performed similar services for the City over the past few years. In FY2023, $30,000.00 has been budgeted in the Water Fund (06-34-47-4418) and remains available for this work. The project start time will be determined based on contractor availability and should take three weeks to complete. Staff is anticipating that the majority of the survey work will occur during the spring of 2023. ACTIONS PROPOSED: Approve Resolution No. 23-R-0030 authorizing the Mayor to execute a contract with Consulting Engineering, Inc. of Strongsville, Ohio, for the 2023 Water System Leak Survey for a contract amount not to exceed $26,349.75. ===== PDF PAGE 37 ===== [Extraction: OCR (rendered-page OCR)] CITY OF WEST CHICAGO COMMITTEE RECOMMENDATION: The Infrastructure Committee voted 6-0 for approval.
