1.Schieffelin Road Lift Station & Forcemain Description
Schieffelin Road Lift Station (SRLS) is located on Schieffelin Rd, approximately 0.33 South of
Center Street at Pine Hill Business Center. SRLS was constructed in 1997 as part of a sewer
extension to serve Pine Hill Business Center (DWQ Permit No. WQ0012668).
SRLS consisted of a duplex vacuum prime pumping system, a 6' diameter x 21'-6" deep wet
well, and approximately 2500 linear feet of 6" PVC forcemain. The original pumping
equipment remains in service today. SRLS is equipped with a 55 kW propane powered
standby generator and automatic transfer switch. The 6" force main routes West on
Schieffelin Road and discharges into a gravity sewer manhole at the intersection of Schieffelin
Road and Marco Drive. (Figure 01, 02 & 03).

II.Schieffelin Road Lift Station — Pumping Improvements
SRLS utilizes a duplex vacuum prime pumping system. The major improvement in this permit
modification will be to demolish the existing vacuum prime pumping equipment, control
panel, and associated piping and convert the pumping system to a less maintenance-intensive
submersible pumping system with an above-ground enclosure to house the valves, inter-
connecting piping, and pump control panel (Figure 04, 05 & 06). There will be no
modifications to the wet well, force main or tributary gravity sewer.

A. Forcemain Analysis & System Curve
A system curve was generated to aid in the selection of the new pumps. (Figure 07). A
Hazen-Williams c-factor of 120 and a static head of 23' was used to generate the system
curve. The forcemain discharge elevation is the high point in the system at 433', and the
"Pump Off" water level elevation is 410' equaling a difference of 23' for the static lift
component of the system.

B. Historical Flows
The Town of Apex provided the last calendar year of daily flows to the pump station from
their SCADA system's calculated drawdown. This data indicated the ADF to be 25,000
gallons (17 gpm), and the peak day to be 80,000 gallons (56 gpm).
C. SRLS Firm Capacity Increase
The existing SRLS pumps are rated for 220gpm (single pump flow) resulting in a firm
station capacity of.32 MGD. Although there will be no new wastewater generated by this
project, the proposed submersible pumps are designed to output more than the existing
pumps, which will increase both the firm capacity of the lift station and the scouring
velocities in the 6" forcemain. The new pumps (Figure 08 &09) are sized such the existing
utility service and existing standby generator can start and operate both pumps
simultaneously. Also, pump selection criteria included maintaining 2-8 pumping cycles
per hour at average daily flow.

This pump improvement will increase SRLS firm capacity to .50 MGD. Additionally, it will
increase the velocity in the 6" forcemain from 2.5 feet per second to 4 feet per second.
This will keep the forcemain scoured. Pumping Station Design, (3rd edition) states, "The
lowest design velocity for raw wastewater is 2 ft s to keep grit moving, and a peak daily
velocity of 3.5 ft s is desirable to resuspend solids."
Page 7 of 8

III. Requested Permitting Action
The requested permitting action for this application is to change the pumping system from
vacuum prime pumps to submersible pumps and increase the firm station capacity from .32
MGD to .50 MGD. All previously permitted items shall remain in the permit. Because no new
wastewater will be generated in this project,the receiving sewer was not evaluated and would
be evaluated in subsequent permit modifications that generate new wastewater.
Iv. Summary
■ This project consists of the following improvements to SRLS:
o Demolish existing vacuum prime pumps, piping, and control panel.
o Installation of new submersible pumps with stainless steel discharge piping
to the existing forcemain.
o Installation of new above ground enclosure to house new plug valves, check
valves, inter-connecting piping, and pump control panel.
■ The existing generator is adequately sized to start and run both new pumps
simultaneously.
■ The new pumps will change the station firm capacity from .32 MGD to .50 MGD.
■ Pump cycles will be maintained to 2-8 cycles per hour.
■ The rated flow of the new pumps will change the forcemain velocity from 2.5 ft/s
to 4 ft/s.
■ There will ne no wastewater generated by this project.
Should you have any questions regarding this request, please do not hesitate to contact
me.
Sincerely,
Zach C. Hinnant, PE

Tanvir,
See below responses in red.
Additionally, I have attached a revised package with a new section in the project narrative
showing the historical pump station flows. I also revised the permit application to include the
existing 30 linear feet of 8" gravity sewer and 2500 linear feet of 6" force main that will remain. I
have indicated them as such on the permit application. Lastly, I indicated the existing 8" gravity
sewer and start and end points of the existing 6" force main on the maps.
Please let me know if you have any more questions.
Thank you.

Hello Randal and Zach,
After reviewing the Fast Track Sewer System Extension Application for Apex-Scheifflin Road Lift Station
Improvements, additional information is required in order to further process the application. Please provide
the following information by September 11, 2024, and note that the requested information must be submitted
within 30 days of this request, or the applicant will be required to submit a new application and application fee
in accordance with 15A NCAC 02T .0107.
1. Is this an ARPA funded project? If so,-please include the DWI assigned ARPA project number in
your response.
No,
2. As this is an upgrade of the existing pump station, no FTSE is required. However, historical flow
data is necessary to support the pump capacity.
Yes. Historical flow data included in project narrative in the attachment.
3. Section VII.1 does not include any gravity sewer; however, the previous permit mentioned
approximately 30 linear feet of 8-inch gravity sewer. The previous permit also mentioned about
2,500 linear feet of 6-inch force main. Will any of the existing structures be abandoned? If not,
please include everything in the FTA. Mention 'existing', 'new' as necessary.
No. Existing facilities to remain are indicated in the revised permit application in the
attachment.
4. Can you please exact locations of the gravity sewer and force main on the map (start and end
points)?
Yes. I indicated the existing 8" gravity sewer and start and end points of the existing 6" force
main on the maps in the attachment.
