AECOM Delivered. 558 North Main Street Oshkosh,WI 54901 aecom.corn July 25, 2019 RECEIVED AECOM Proposal No. OPP-953327 JUL 2 5 2019 Mr. James Rabe DEPT OF PUBLIC Wp Director of Public Works OSHKOSH, WISCONSIRKS City of Oshkosh N 215 Church Avenue Oshkosh,WI 54901 jrabeAci.oshkosh.wl.ur Proposal for Completion of 2019 Leak Detection Services in Oshkosh,Wisconsin Dear Mr. Rabe, AECOM Technical Services, Inc. (AECOM) is pleased to submit this proposal to conduct a Leak Detection Survey on approximately 100 miles of water main in the City of Oshkosh (City)'s water distribution system in 2019. AECOM has been completing this work for the City for over 10 years. Our field staff are very familiar with the City water distribution system's design and layout in the City. We have worked closely with City staff to verify potential leak locations. This work is a critical part of actively reducing the non-revenue water. This work is an important part of the water management best practice procedures as expected by the Public Service Commission of Wisconsin. Our extensive experience and understanding of the importance of this work allows AECOM to provide the service in a cost effective and efficient manner. Historically, the leak detection services have divided the City into three areas, allowing the entire City to be completed in a three year cycle. The services proposed in this agreement represent the third phase of investigation activities to complete the mosk recent cycle through the City. The first and second phases of this current cycle were completed by AECOM in 2017 nd 2018. This third phase includes approximately 100 miles of water distribution system that were not included in the previous two phases. The 2019 scope of work(Phase 3)area is generally described as all area within the City limits in the southern and western quadrants of the City bound south of W 20th Avenue, west of N Koeller Drive(ie 1-41)and area in the northwest quadrant of the City north of W Linwood Avenue and west of Jackson Street. A copy of the City of Oshkosh Water Leak Detection Overview Map depicting the Phase 3 investigation area is attached. The purpose of the annual surveys is to identify specific points of leakage such that system rehabilitation can be undertaken and lost water reduced. The remainder of this proposal discusses the scope of services to be completed, schedule, information/assistance required from client and compensation. SCOPE OF WORK Services to be provided are as follows: • Meet with City to review existing water distribution systems maps, pertinent water system reports and the schedule for conducting the leak detection field services. • Conduct a leak detection and location survey with sonic detection and computer correlation equipment on approximately 100 miles of the water distribution system. Physical contact will be made with the system at exposed valves and fire hydrants.After the initial sonic leak survey of a portion of the system is completed, indications of leaks will be verified a second time. after which leaks will be located with a computer-programmed leak correlator designed to identify leak locations without drill holes or excavations. Where leakage into a storm or sanitary sewer is suspected, a visual examination of the appropriate sewer will be conducted. All equipment used will be non-intrusive. Valves and hydrants will not normally require operation during the survey and K.\PROPOSAL\City of Oshkosh\OPP-953327_2019 Leak Detection\OPP-953327_2019 Leak Detection Proposal.docx 1/4 AECOMImagine it.

This survey will be conducted primarily during normal working hours,with additional leak detection being conducted during late evening and/or early morning hours in areas of high traffic volume. • Prepare an inventory of defective system components such as valves, hydrants, meters and curb stops, which are noted in the course of carrying out field activities. • AECOM will furnish a fully-equipped vehicle, including all sonic leak detection equipment,tools and safety equipment for the duration of the project. Our Fluid Conservation System computer leak correlators will be utilized to pinpoint leaks. • Prepare annual Leak Detection report and submit three(3)copies of the report showing the results of the 2019 investigations. The report shall include a summary of the project and a list of leakage located by type, location, and estimated quantity of leakage. The final report will contain recommendations for future work based on the results of this survey. SCHEDULE • Leak Detection Phase: approximately 4-5 weeks • Annual Report: approximately 2-4 weeks after field work CLIENT'S RESPONSIBILITIES Client, at its expense, shall do the following in a timely manner so as not to delay the Services: Furnish AECOM the following information/reports/assistance, all of which AECOM may rely upon without independent verification in performing the Services: • All available street maps and water distribution system maps. • One(1)experienced person with a good working knowledge of the water distribution system to assist on a part-time basis in field activities, such as location of system components. • Access to valves and c rb stops by uncovering and cleaning valves and curb boxes, where re1uired, prior to initiation of field activitie . CLIENT REPRESENTATIVE Designate a representative for the Project who shall have the authority to transmit instructions, receive information, interpret and define Client's policies, and make decisions with respect to the Services.
