RE: Professional Services Agreement with AECOM for 2022 Water Distribution System
Leak Detection Services ($30,475)
Unidentified water loss within the water distribution system continues to be a topic of concern for the
Wisconsin Department of Natural Resources (WDNR) and the Public Service Commission of Wisconsin
(PSC). One of the most successful and cost effective recommendations that the Water Utility has received
from the WDNR and PSC is to hire a specialized outside consultant team to perform an annual leak
detection survey on our water distribution system.
The purpose of the annual survey is to identify specific points of leakage that would otherwise go
undetected throughout the year. Past surveys have yielded an average of 25 – 50 different leak locations.
If these locations are not detected, they have the potential of wasting 150,000 – 400,000 gallons of water
per day in unidentified water loss. As leaks are identified by the team, they are immediately
communicated to Water Distribution staff for repair.
The Department of Public Works has been working with AECOM on this leak detection survey program
for the past fifteen (15) plus years. The program divides the City into three (3) zones, each covering
approximately one-third (1/3) of the distribution system. Each zone consists of approximately one
hundred (100) miles of water main.
The Department of Public Works requested a proposal from AECOM to perform the leak detection
survey again this year due to their staff familiarity with the City of Oshkosh and our water distribution
system and their past proficient experience with performing these services.
This year’s work is estimated to cost approximately $30,475. The cost for these services is funded in the
Water Utility Operating Budget (Account #05411867-6401-08673/Water Distribution Maintenance-PS -
Engineer/Survey/Appraisal-Maint-Mains and #05411867-6401-08675/Water Distribution Maintenance-
PS - Engineer/Survey/Appraisal-Maint-Services).
Chapter 12 of the Municipal Code of the City of Oshkosh provides that professional services of a specialized
nature, including engineering services, may be procured without the use of formal, sealed quotes. In
accordance with Section 12-16 of the Code, I am hereby submitting this report regarding this professional
services agreement.
Please contact me if you have any questions concerning this professional services agreement.
