investigation activities to be completed on the City of Oshkosh Municipal Water Supply which
consists of approximately 100 miles of water main piping. Historically the City has completed the
total comprehensive City wide leak detection survey over a three(3)year period (i.e, 100, miles per
year). The first and second phase of this program was completed by AECOM in 2014 and 2015.
This proposal has been prepare for the third phase of those services and is intended for the
remaining approximate 100 miles of municipal system outside the 2014 and 2015 survey areas.
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 Services
Services to be provided for the Project 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 pinpoint 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
