PROJECT NAME: Tenth Street Pump Station Expansion
OWNER: CITY OF JEFFERSONVILLE PROJECT NO: 423098
You are hereby directed to execute promptly this Field Order which interprets the Contract
Documents or orders minor changes in the Work without changing the Contract Sum or Contract
Time.
If you consider that a change in the Contract sum or Contract Time is required, please submit your
itemized proposal to the Engineer immediately and before proceeding with this Work. If your
proposal is found to be satisfactory and in proper order, this Field Order will, in that event, be
superseded by a Change Order.
Description:
Cut and cap existing 30" force main upstream of 24" tie -in.
The revised Field Order No. 33 is required because the force main wye fitting was not located correctly
on the record drawings. Instead of under the sidewalk it was located under the street and encased in
concrete, requiring additional excavation, traffic control, and pavement restoration.

10 STREET PUMP STATION EXPANSION PROJECT
FUNCTIONAL SPECIFICATION
Created by: Darryl W. Evans, P.E., HDR Engineering, Inc.
Rev. 0, Date: 10/10/11 (Draft)
Rev. 1, Date: 10/26/11 (Review Mtg.)
Rev. 2, Date: 11/07/11 (Working Copy)
Rev. 3, Date: 06/19/12 (Revise start /stop logic for deeper wet well volume.)
The following provides for the System Integrator(s) background information and written description of
the control system functionality required to achieve the desired operation of the pump station as
described in the original contract documents and revised via discussions with the City of Jeffersonville
( "City ").
Background
The 10 Street Pump Station ( "Station ") receives flow from a 90" combined sewer, two 24" sanitary
sewers, and a 6" sanitary sewer. The present firm capacity of the station is approximately 15.4MGD
delivered from 5 constant speed pumps via 24" and 18 "force mains to the Jeffersonville Waste Water
Treatment Plant ( "WWTP "). A Consent Decree with the EPA effective November of 2009 requires the
City to initially receive at the WWTP a 3 -hour maximum ( "3hrMax ") of 35MGD from all flow sources
including the Station. Upon completion of ongoing upgrades at the WWTP, this value will be increased
to a 3hrMax of 50MGD. After 3- hours, these maximum values will be reduced to a sustained maximum
flow ( "SustMax ") that will be determined by WWTP personnel through trials upon completion of the
WWTP upgrades. The WWTP also receives a maximum of 7.2MGD from Mill Creek Pump Station,
6.0MGD from Spring Street Pump Station, and an unknown but negligible flow from the Krunchers plant.
The combined and sanitary sewers supplying the Station will deliver far more than the Station or the
WWTP can accept but the WWTP can accept more than the Station will presently deliver. Therefore, the
Station improvements will include replacement of the 5 existing pumps to provide 40MGD of firm
capacity and 50MGD peak capacity with a throttling mechanism to limit flow to the WWTP. Other
improvements upstream of the pump station include a combined sewer overflow ( "CSO ") weir and
screening process to return screened material back to the flow stream, automated mechanical bar
screens, and grit removal equipment to remove materials from the flow stream prior to pumping.
Improvements downstream include a new 36" force main to parallel the existing 24" force main and a
new flow meter on each. A new electrical service and standby generator are included to support the
increased energy demand. The City's existing SCADA system coupled with a new PLC -based control
system at the Station will be used to trim the flow from the Station to achieve the maximum WWTP
flows indicated above.
