Crane Pumps & Systems is pleased to provide the following preliminary design analysis which
examines the use of a low-pressure sewer system utilizing the Barnes Razor Grinder Pump for
the Fairway Acres project in Brunswick County, NC. The process includes a mass flow calculation
and system performance evaluation based on using pressure sewer force mains. The low
pressure sewer approach provides not only a technical solution, but also an economic advantage
to be realized with low up front and 0&M Costs. The hydraulic analysis incorporates force main
and pumping system details (including tributary grinder pump station inputs), head loss
calculations based on respective force main size, length and system elevations, and pump
performance curves for each pump station.
Analysis Description
Using the maps and project data provided by Timmons Group, we ran the enclosed preliminary
pressure sewer piping analysis. This was analyzed by utilizing the Rational Method model as
recommended by the EPA Manual 625/1-91/024 in conjunction with the KY Pipe hydraulic
modeling software. In this way we are able to model using both theoretical data as well as actual
conditions. Computations are based on the Hazen -Williams formula for friction loss, using
calculations of cross -sectional area and flow rate to determine the capacity of the existing force
main while checking to ensure scouring velocity of approximately 2.0 FPS or higher. A C factor of
140, PVC SDR 21pipe and an average daily flow per unit of 480 GPD are also used.
The models were created using assumptions that only residential units would be connected to
the system, and that it would be terminating into a manhole on the southern portion of the
system.
This pressure sewer system accounts for 50 simplex stations, and pipe routing was laid according
to the sewer profile provided by Timmons Group.
Valve Recommendations
Good engineering practice suggests the installation of cleanouts / flushing connections with
associated shutoff valves in pressure sewer systems. The flushing locations are essential for
servicing sewer mains and can be used to isolate segments of a pressure sewer network for
servicing. The connections serve as locations for high pressure sewerjetting or flushing activities.
There are three primary applications for flushing connections in low pressure sewer systems;
located at the end of each main, at pipe intersections, and in -line locations. Equipment
capabilities for sewer jetting or cleaning equipment available to the municipality should also be
considered.
Cleanout locations are routinely installed in the same valve pit as automatic air release or vacuum
release valves. Representative drawings are available upon request.
Terminal Cleanout Locations:
Located at the terminal end of each pipe segment.
Inline Cleanout Locations:
Located in 800 to 1,200 foot intervals. Interval location also dependent upon type of
service equipment available to complete the flushing process.
Junction Cleanout Locations:
Located at intersections in pipe, at changes in direction in pipe and at changes in pipe
diameter.
We also recommend installation of a Crane Stainless Steel Curb Stop/Check Valve assembly in
the discharge line between the grinder pump station and the force main. It is normally acceptable
to have the Curb Stop/Check Valve assembly installed near other utility shut off valves for
convenience of access, though they may be installed closer to the station.
Rational Method Formula
There are various equations, charts and formulas that exist when trying to determine design flow
in a low pressure sewer system. In addition, local departments of environmental regulations may
offer site specific guidelines when determining design flow. Crane utilizes the Rational Method
Formula, which the EPA recognizes "has almost exclusively become the accepted method of
practice." (EPA Manual 52511-911024) This method attempts to predict average flow produced
by the system throughout the day, taking into account peak flow. This flow is directly related to
the number of homes connected to the system. The flow is not dependent on the output from
any pump being constant or the same as others, and it works with all makes and models of grinder
pumps. It also reflects a snapshot of the system at a given moment — not a best case scenario.
The baseline formula of the Rational Method is —
Q = AN+B
• Q = Predicted flow derived from input data
• A = A coefficient that adjusts based on average daily flow
o EPA National Average is 200 GPD/EDU
o Divide GPD by 400 to determine A value —will typically be .5
• N = Number of Equivalent Domestic Units (EDU) or lots
• B = Minimum flow one pump will produce at maximum static head with no friction loss
Utilizing the Rational Method on this system provides the following flow -
Scenario
A = 1.2 (480 GPD/400)
N = 50 (50 EDUs)
B = 28 GPM (pump curve included below)
Q = 88 GPM System Flow
Pipe Charts
Utilizing the above Rational Method formula on the individual segments of the system, we were
able to size the pipe to reach desired scouring velocity of 2.0 FPS while not exceeding 5.0 FPS.
The below charts illustrate this by highlighting the number of EDUs required to reach the target
velocities given the defined system parameters.

MEMORANDUM
TO: John Wall, PE — Timmons Group
FROM: Ashley Kabat, PE — Timmons Group
DATE: July 7, 2023
RE: Fairway Acres Downstream Sewer Capacity
Mr. Wall,
P 919.866.4951
F 919.859.5663
www.timmons.com
Timmons Group communicated with Amy Aycock from Brunswick County about the sanitary sewer
capacity available for the Fairway Acres development. After taking into consideration existing and
anticipated flows, Timmons Group and Brunswick County agree that there is adequate capacity
downstream if the proposed development connects to the existing sewer on Oakbrook Drive. The email
correspondence is attached. Please advise if a more extensive sewer study is required for this project.
Sincerely,

Subject: RE: Brick Landing Sewer
Attachments: Oakbrook GIS.pdf
Hi John,
I have reviewed this proposal and it looks like the design will work to tie into the Oakbrook Dr. (I have attached a GIS
snapshot, it looks like.this address is 1770 Oakbrook Dr which will have the easement.) The only issue with this design, is
the low pressure forcemain will also go through the Bricklanding golf course property before the Oakbrook Dr lot, so you
will also need to get an easement from them.
There is still flow available in this system....
Please let me know if you have any other questions.
Thank you,
Amy A�cocL

Hi Amy,
We are working through the Fairway Acres plans (fka Hewitt Tract) and we have a small plan change with the low-
pressure sewer tie-in. Previously we proposed to tie into the manhole on Deerfield Drive, but the owner had issues with
obtaining an easement on the vacant Saccoccio property that would get us to the existing manhole. We had a second
option of tying into the manhole on Oakbrook Drive SW, which we have pursued. The owner has purchased the vacant
Hendrix lot and we will be utilizing that to reach the Oakbrook Drive SW manhole.
Do you foresee any issues with our revised low-pressure route and tie-in, or have any preliminary comments? Previously
you had let Ashley know that the downstream sanitary sewer had available capacity. The Deerfield Dr sanitary and
Oakbrook Drive SW sanitary sewer both gravity to the same Lift Station.
