SUBJECT: Fast Track Sewer System Extension Application -Town of Fuquay-Varina
NCDOT Project R-2721 B, 1-540 Triangle Expressway in Wake County
The attached application for sewer extension is being provided for the proposed
installation of a relocated gravity sewer line along US Highway 401 in Wake County.
This work is being performed to replace the existing 8" gravity sewer installed within
NCDOT right-of-way along US Highway 401 which will be in conflict with proposed
highway/bridge construction. Relocation of this gravity sewer is required due to
proposed construction of a new interchange at this location. Interchange construction
will provide new bridges, approaches and ramps in the immediate location of the
existing sewer.
Hinde Engineering has been contracted by NCDOT to provide the engineering design
for the proposed relocations and is the engineer of record for this work. If there or
questions or if additional information is required, please contact Hinde Engineering at
the number listed above or by using the email address provided below.

Subject: Additional Information Request: Fuquay-Varina NCDOT Project R-2721B
Hello,
After a review of the provided documentation submitted for the alternative design request for the Town of Fuquay-
Varina's NCDOT Project R-272113, 1-540 Triangle Expressway project and after consultation with a colleague, we have
several comments that must be addressed before this alternative design can be approved in accordance with 15A NCAC
02T.0105(n), listed as follows:
1. Detail depictions of the siphon connector boxes, including the profile and plan view of the siphon entrance/exit
configuration, must be provided on the plan set.
2. Per the Minimum Design Criteria, the maximum C-value used should be 140. Please revise the calculations to
reflect this value.
3. The provided Hazen -Williams analysis is a rough approximation of the function of the siphon, however, it does
not appear to account for all design aspects. Please provide updated calculations to address the following:
a. Pipe fitting friction losses,
b. Head loss through the influent box, including any weirs if applicable,
c. The actual pipe length of 660 linear feet (as opposed to the horizontal distance of 600 feet),
d. The variation in static head between the small and the large barrels (the vertical head is shown to be
—6.5 feet for the smaller barrel and —7.5 feet for the larger one),
e. Function of the smaller barrel when the flow into the box is higher than the top of the smaller barrel,
but below the larger pipe's invert due to the indicated vertical separation of the inverts of 12-inches.
4. The flow calculated for the incoming 12-inch gravity sewer appears to indicate that only the four listed pump
stations are contributing flow to this line (two existing, two future). Please clarify if there are any other sources
of incoming flow into this line.
5. We have concerns about the inside diameter of the single 5-inch HDPE (indicated to be approximately 4.2" ID)
barrel, specifically, under the current conditions when flow will likely never reach the invert of the larger barrel.
What contingencies are in place should that line become damaged, clogged, or otherwise inoperable prior to
reaching full flow levels where the larger barrel will be utilized regularly? How will the siphon function if the
smaller pipe is inoperable?
Please provide a digital copy of all documents above in PDF format via email, including a full set of plans. If you have any
questions, please let me know. Thanks!

The 4-inch diameter force main that I referred to is a replacement in kind of an existing 4-inch diameter force main
sewer from a treatment plant that is well off the project. The new section of pipe is slightly offset to the north side of
the existing and will avoid drainage conflicts and provide a higher quality of material than the existing. Given the
language in 15A NCAC 02T .0303 we believe the new section of line should be permitted by regulation.
hope you find this information acceptable. Please do not hesitate to contact me if you have questions or concerns.
Thank you...

Thanks Mr. Wilkins,
I got your voicemail. In it you mentioned lowering a line to avoid some drainage conflicts. Is the line that is being
lowered an existing line (not a proposed line that was included in the permit application)?
If so, I think it may need to be included in the permit, since it will be changing the vertical alignment of the line
Below is 15A NCAC 02T .0303(4) that describes what types of rehab work that do NOT need permits. If you are lowering
an existing line in -place, and thus changing the vertical alignment (Item A), it would need a permit. 1 think it could be
included in the permit that we're about to issue. If so, could you please provide a brief description of how much line will
be lowered and by how much.

Mr. Robinson, I apologize for the late response but as I mentioned in an earlier email I was out of the office all of last
week. I would like to respond to the four items you identified in your email as follows:
1. Item IX.6 was checked "No" for high priority line, but it specifically says a siphon is a high priority line. With your
permission, I'll change this item to "Yes". Item IX.6 should be checked "Yes" as you mentioned and 1 agree to the
change you suggested.
2. In Item X.2, the engineers name was not printed in the blank... and it's hard to read the signature on the seal. I
assume this is your (Mr. Wilkins) signature, but please confirm. The name that should be printed in the blank
should be Ronald B. Wilkins, PE and the signature on the permit application is mine (PE 10157).
3. Based on the variance language we received from our Central Office, it appears that the size of pipe has
changed from what was initially included on the application (660 feet of 5" pipe instead of 4" ). Please provide
us a list of the lengths of the different sized pipes. Based on comments received from the DEQ Central office we
did upsize the low flow barrel of the siphon to 5" diameter HDPE and the proposed installation length of 660
linear feet is correct. The 8-inch diameter gravity sewer has a proposed length of 560 linear feet and is PVC SDR
35, the 10-inch diameter HDPE overflow barrel of the siphon has a proposed length of 660 linear feet, and the 12-
inch diameter (PVC C900) gravity sewer has a proposed length of 3634 linear feet. Our plans also show a 4-inch
diameter farce main that is being lowered to avoid conflicts with construction. The relocated section of this line
will be PVC C900. Additionally the line remains in the same right -of woy, there is no increase in size, length or
demand on this line so in accordance with direction we have received from DEQ the line was not included on the
permit application.
4. To follow-up on Item 3 above, since it's been such a long time since the application was first submitted, please
review the application and let us know if there were any other changes that have been made as a result of the
variance review or anything else. The change in diameter of the low flow barrel of the siphon from 4-inch
diameter to 5-inch diameter is the only change that we have made to the design of the Fuquoy-Varina sewer
system along this section of the project.
I hope you find this information acceptable. Should you have any questions or require additional information please do
not hesitate to contact me. Thank you...

Mr. Wilkins and Mr. Meyers,
We received confirmation from our Central Office yesterday that the variance for this project has been granted and we
could proceed with issuing the permit.
I've reviewed the sewer extension application and have a few questions/comments.
1. Item IX.6 was checked "No" for high priority line, but it specifically says a siphon is a high priority line. With your
permission, I'll change this item to "Yes".

2. In Item X.2, the engineers name was not printed in the blank... and it's hard to read the signature on the seal.
assume this is your (Mr. Wilkins) signature, but please confirm.
3. Based on the variance language we received from our Central Office, it appears that the size of pipe has
changed from what was initially included on the application (660 feet of 5" pipe instead of 4"). Please provide
us a list of the lengths of the different sized pipes.
4. To follow-up on Item 3 above, since it's been such a long time since the application was first submitted, please
review the application and let us know if there were any other changes that have been made as a result of the
variance review or anything else.
Thanks,

02T.0105(n). See Condition 1.1 for more details.
In the permit description paragraph —this will be a separate item and you'll list any other permitted components as
normal:
A 2-barrel inverted siphon structure crossing under 1-540, consisting of approximately 660 linear feet of 5-inch gravity
sewer and approximately 660 linear feet of 10-inch gravity sewer as well as the requisite inlet/outlet structures;
Special Condition page:
1. Pursuant to the provided documentation in the original application package as well as the variance request received
April 22, 2019 with additional information received August 21, 2019 and February 3, 2020, as submitted by Hinde
