CI P 7101335
DATE: December 1, 2015
Sealed bids were received for the 2015 SCADA (Flow Metering Stations) Manhole
Installation Project. City Engineer Gus Psihoyos recommends award of the construction
contract to the low bidder, Connolly Construction, Inc., in the amount of $127,339.97,
which is 20.97% over the estimate of probable cost. The cost increase is due to the
complicated nature of the project with the incorporation of fiber optic communication to
each of the manholes. Sufficient funds are available in the project budget.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

DATE: November 25, 2015
INTRODUCTION
The enclosed resolution authorizes the award of the construction contract for the 2015
SCADA (flow metering stations) Manhole Installation Project.
BACKGROUND
The City of Dubuque, Iowa has entered into a Consent Decree in the case of The
United States of America, and the State of Iowa v. The City of Dubuque, Iowa, Civil
Action No. Case 2:11-cv-01011-EMJ, Civil Action Number 2008V00041, DOJ Case
Number 90-5-1-1-09339, United States District Court for the Northern District of Iowa.
The provisions of the Consent Decree apply to and are binding upon the City and its
officers, directors, employees, agents, servants, successors, assigns, and all persons,
firms and corporations under contract with the City to perform the obligations of the
Consent Decree. The City is required to perform collection system flow monitoring per
a schedule established in the Consent Decree, the City is flow monitoring beyond the
schedule using supervisory control and data acquisition (SCADA) system technology in
sanitary sewer manholes. We are requesting several sanitary sewer manholes (flow
metering stations) be replaced to provide the best conditions for permanent flow
monitoring.
DISCUSSION
The Consent Decree identifies five sewersheds that are required to be individually flow
metered for specific periods over a five year schedule. While flow metering for short
periods of time may result in locating inflow under one or two rain events, it will not
capture how the sanitary sewer system will perform under different or changing rain
patterns more commonly seen. Long term or permanent flow monitoring is a method
used to continually meter the sanitary sewer system, so staff can observe changes in
flow; document and measure how rain events impact the system; and provide valuable
feedback on how capital improvements have or have not reduced inflow. The proposed
permanent flow metering stations are designed to not only monitor and record flows, but
also report them in real-time triggering an alarm if there are any changes in the system
FAPROJECTS\Storm and Sanitary\Sanitary\SCADA Manholes\Council\INITIATE\Initiate Memo-2015 SCADA Manhole Installation
Project.doc
where a flow meter is in place. In the event of increased flows or water level changes, or
a fouled meter sensor, the flow metering stations will report via the SCADA system to
Public Works, the W&RRC, and the Engineering department for immediate response to
reduce the possibility of sanitary sewer overflows.
This project involves the replacement of four(4) sanitary sewer manholes and their
conversion to permanent flow metering stations in Sewersheds 7 (a & b), 11, and 12,

DAGIS
The flow metering station for Sewershed 5 is installed and will be operational by
November 11, 2015; and the metering station for Sewershed 10 will be delayed until the
completion of Phase 2 of the Bee Branch project. Portions of some water mains may
need to be relocated as part of this project due to the replacement of the manholes.
