Pump Station Improvements
Eligibility Determination
Project No. E-SEL-T-00-0031
Dear Mayor Young:
The subject plans and specifications have been reviewed for eligibility by the
Construction Grants & Loans Section of the North Carolina Division of Water Quality.
Eligibility for State Emergency Loan funding is determined as follows:
Modifications to the existing Red Bud Creek Pump Station to allow connection of a
portable engine driven emergency pump with discharge into the existing force main, and
procurement of an 1800 GPM portable engine driven emergency pump.
Funding for this project is limited to the proposed loan amount of $112,780
established and approved by the Environmental Management Commission. In the event
that received bids exceed this established amount and local funds are not adequate to
award contract(s), it will be necessary to consider all alternatives including redesign, re -
advertising, and rebidding.
Neither the State or Federal Government, nor any of its departments, agencies or
employees is or will be a party to the invitation to bids, addenda, any resulting contracts
or contract negotiations/changes.
In accordance with the Federal Regulations, the Recipient is required to assure
compliance with the OSHA safety regulations on the subject project.
It is the responsibility of the Recipient and the Consultant Engineer
to insure that the project plan documents are in compliance with

Re: City of Henderson
Red Bud Pump Station Emergency Loan Application
Dear Mr. Schuster:
M&C 01406-0002 (10)
AN 13 ?jq)
The City has experienced continuing overflow and bypass conditions at the Red Bud Pump
Station. As you are aware, they are proceeding with implementation of a pump station,
interceptor, and force main expansion project.
However, given the continuing nature of the problems and the length of time required to
complete the comprehensive project, the City wishes to pursue the immediate installation of a
semi -temporary portable pump at this location which would run during these rainfall events. The
pump would be capable of an output of up to 2,000 GPM (compared to the current pump design
capacity of 965 GPM and actual output of approximately 800 GPM).
Due to the magnitude of the expenditure and the timing relative to the fiscal year, the City
wishes to apply for funding from the Emergency Loan Fund of the Clean Water Revolving Loan
and Grant Program. Mr. Blowe informed us that the Raleigh Regional Office is responsible for a
determination of eligibility to apply for those funds. Mr. Blowe indicated there is approximately
$1.0 million available in that fund at present.
We understand that it may appear unusual to ask for loan eligibility for a "temporary' or
.'portable" piece of equipment. We would point out that this unit will be used extremely
frequently (especially during wet weather) at this installation for up to two years while the
comprehensive project is implemented. Thereafter, there will be occasions for its use at many
locations in the system. Chief among these would be at the Sandy Creek Pump Station, a 3.8
MGD station that has occasional capacity deficiencies at this time. We can foresee the
utilization of this pump at the wastewater treatment plant and other significant pump stations as
well. The unit is provided with means of control and modulation of the pumping rate to suit the
particular situation in terms of influent flow and capacity of downstream receiving facilities.

Please don't hesitate to contact me if you have any questions or comments, or require
additional information.

RE: City of Henderson
High -Unit Cost Grant Application
Dear Mr. Evans:
M&C 01406-0001(10)
Please find enclosed the revised grant application and amendment to the preliminary
engineering report for the Nutbush Interceptor and Red Bud Pump Station project. The bulk of
the application package and documentation from the March 31, 1999 submittal remains in
effect, but the project scope has been amended somewhat. The major amendment consists of
the inclusion of the Red Bud Pump Station parallel force main in this project rather than in a
future phase. Also, the budget estimate for the pump station upgrade has been modified
somewhat based on more current estimates received during the design process. These
modifications are discussed in the attached PER amendment, and are reflected in the revised
project budget sheets in the grant application. Of course, the full maximum S3 million grant
had been requested previously, and this remains the request.
Please don't hesitate to contact me if you have any questions or require additional information.

AMENDMENT TO
PRELIMINARY ENGINEERING REPORT
I. Introduction
Since the original grant application and preliminary engineering report were submitted in
March, 1999, there have been continued problems with overflows and bypasses at the Red
Bud Pump Station. Base flows, as well as infiltration inflows, have resulted in chronic overflow
bypass conditions even during something less then extreme rainfall events. Faced with this
situation, the City has elected to pursue the relatively complete pump station installation and
concurrent parallel force main installation in the initial project, rather then the previously
discussed phase implementation.
Therefore, the pump station phasing contained on page 12 of 15 of the PER has been
amended and the proposed station upgrade described on the attached revised pages 12
through 15, with revised Figure 1 and Tables 9-11.
Project budgets have been revised accordingly.
0 ff'AOBNOW UOUT ET ER Ame menttl

City of Hendersof.
Pump Station, Interceptor, and Collection System 1/1 Reduction Improvements
V. Pump Station Upgrade
The Red Bud pump station has received considerably more detailed investigations than
several other stations since it has been subject to chronic overflow/bypass conditions, is
mentioned specifically under the City's SOC. The existing pump station at Red Bud is having
difficulty in keeping up with the extraneous flows due to the level of 1/1 in the Red Bud system.
Even once some of the 1/1 flows have been removed through the previously referenced repairs,
the station will still need an upgrade to convey current and projected flows. See Table 9 for
pump station calculations.
The initial post-1/1-repair flow to the pump station is expected to be approximately 1,410 gpm.
Of the three major drainage basins in the City's system, Red Bud has exhibited the fastest
growth, owing largely to the proximity to interchange areas of 1-85 and the new servicing of
Vance -Granville Community College. The method for assigning projected future flows is
described previously and the results are shown in Table 10 with system and pump curves on
Figure 1. Therefore, the expected flow at the end of the 20-year planning period is 4,100 gpm.
The pump station is currently designed for 965 gpm, but has had difficulty maintaining this
output. The older magnetic drives themselves account for a 5-8% loss from synchronous
speed, dramatically reducing output, and the force main (given the low design velocity of only
2.0 fps) seems to have a tendency toward deposition of grit and grease build-up. Given the
extremely flat pump curve, this can have a dramatic effect on the pump output, which has
been as low as 800 gpm.
The pump station will be upgraded by installation of new pumps and construction of an 18"
parallel force main from the station to the existing discharge point on Coble Boulevard.
Phase
The existing building and structures are generally in good condition. The pumps and motors,
however, are undersized for the high flow conditions. In order to convey the required 4,1000
gpm and maintain a reasonably wide operating range, the station will be converted from duplex
to triplex configuration. Pumps will be designed to operate in lead -lag -standby mode. Since
one pump will be sufficient for the immediate future, and the generator is virtually new, the
existing generator will be retained and planned to be replaced at such time as two -pump
operation is routinely required. In order to provide sufficient room for the VFD's in a three -
pump installation it is planned to utilize dry -pit submersible pumps. For cooling purposes,
these are oversized frames and motors, resulting in 200 HP sizes. Table 9 and Figure 1 have
been revised to show the pump conditions and systems curves for the proposed
improvements. The outdated magnetic drives will be replaced with modem variable frequency
drives (VFDs). The remainder of the station, including the existing generator. is adequate and
will remain in place for Phase I.
A telemetry/SCADA system must also be installed to monitor the station from a remote
location. Finally, new monitoring and controls for the wet well, equalization basin, chemical
feed system, bar screen, and other mechanical systems will be installed.

VI. Interceptor Design
As the flows are pumped from the Red Bud pump station, they are conveyed to the 18 and 24"
gravity sewers at on Coble Boulevard in Nutbush basin 11 and on to the treatment plant.
Currently many, if not all segment surcharge, and some portions of the gravity sewer overflow
during peak events. With the addition of flow due to the Red Bud pump station upgrade, the
existing sewers will not be able to properly handle flows. Therefore, an upgrade to the existing
sewers will be performed.
The current post -repair required peak flow from the Red Bud pump station is 1,410 gpm.
Therefore, this sewer must be capable of conveying this flow, whether through upgrade of the
existing sewer or installation of a parallel sewer of larger size.
When designing this sewers upgrade and installation, the overall capacity of the treatment
system must be considered. This interceptor carries flows from not only the Red Bud pump
station, but from the Nutbush and Sandy Creek basins as well. Therefore, the downstream
portion of the sewer (that carries flows after the Nutbush and Sandy Creek connections) must
be designed to carry the current and anticipated future flows at the treatment plant. The
anticipated flow at the treatment plant is 7.0 MGD average day, or slightly over 12,000 gpm
peak flow, in twenty years. The anticipated flow at the Red Bud pump'station (with the
expected I/I reduction) is 4,100 gpm in twenty years. Each flow is assigned a peak factor of
2.5 to allow for the diurnal variation in flow. This new interceptor, along with the existing
sewer, must be capable of conveying this future flow, beginning at 4,100 gpm on Coble
Boulevard and ending at 12,000 gpm at the treatment plant.
There are a few minor tributaries to this interceptor between these points which had relatively
insignificant amounts of flow. The major tributary which results in the flow increase from 4,000
to 12,000 gpm is the Sandy Creek interceptor and basin. Although presently this flow enters
the interceptor on the north side of 1-85, a future project will extend and relocate the Sandy
Creek force main to Radio Lane will it will combine with the Red Bud flow. From this point to
the plant the interceptor sewer must be capable of conveying 12,000 gpm. Based on the
topography of the interceptor route, these flows will require a 30 inch interceptor from Coble
Blvd. to Radio Lane and a 42 inch interceptor from Radio Lane to the treatment plant. With
these pipe sizes and attendant slopes the 20 year design flows are conveyed at a percent of
depth ranging from approximately 40% to approximately 70% depending upon the specific

Vill. Conclusions
There exists in Henderson an amount of Infiltration and Inflow (1/1) that causes excessive flow
and/or overflows in the sewer system during wet weather events. These excessive flows are
caused by defects in the sewer system due to the system's age and condition.
Given the observations made during site visits and from the reports generated during smoke
testing, it is believed that the a large percentage of the inflow portion of the 1/1 can be removed
from the system by repairing system defects and resealing joints. It was assumed that 70% of
the inflow can be reduced by making repairs to the sewer system defects identified in the
smoke tests.
The project will result in a reduction of 1/1 throughout the system, with special focus on the Red
Bud pump station. The expected "average peak day' flow reduction throughout the system will
be 1.10 MGD. This 1/1 reduction is the anticipated decrease in the average daily flow on the
peak day of each month. The expected flow reduction at the Red Bud pump station will be
251 gpm. This reduction is the anticipated decrease in the peak instantaneous flow to the
pump station.
The expected cost of the project will be approximately $3,830,000. This cost will include
upgrade of the existing Red Bud pump station, installation of a new 18" force main to operate
in parallel with the existing 14" force main from the pump station to the discharge point on
Coble Blvd., installation of a new 30/42" interceptor to parallel the existing sewer from the
vicinity of Beckford Drive to the treatment plant, and repair of selected defective portions of the
sewer system.
