PROJECT DESIGN NARRATIVE
TO: Town of Burgaw
FROM: Jess Powell, PE
DATE: September 14, 2021
RE: US HWY 117 Regional Pump Station and Force Main Project
Fast Track Sewer Permit - NCDEQ
M&CA: 04576-0012
I. Background
The Town of Burgaw has identified the need for a new regional wastewater pump station (PS No.
2) and force main to serve an unsewered area, east of US Highway 117. In addition to the new
wastewater pump station, the project will include redirecting flow from the existing White Tractor
Pump Station to the new station via a combination of approximately 2,600 linear feet of 8" gravity
sewer and 4" sewer force main.
The project will involve the design and permitting of:
✓ 450 GPM wastewater pump station
✓ 7,700 linear feet of 8-inch PVC sewer force main
✓ 1,340 linear feet of 4-inch PVC sewer force main
✓ 1,220 linear feet of 8-inch PVC sanitary sewer
Note that the 1,340 linear feet of 4-inch PVC sewer force main will be permitted separately as a
permit modification for White Tractor Pump Station.
The new 8-inch force main will manifold into an existing 20-inch force main that conveys the
Towri s wastewater to the Town of Wallace, North Carolina for treatment.
The basis of design for the proposed pump station and associated pipeline improvements are
detailed in the following sections.
H. Demands and Peak Hour Factors
04576-0012 1 September 2021
US HWY 117 Regional Pump Station and Force Main

Flow projections for PS No. 2 were developed based on information provided by the Town. There
are 400 residential units planned for development within the service area. In addition, an existing
pump station (White Tractor PS) currently flows into a small diameter gravity sewer which is
rapidly approaching the maximum capacity. To alleviate the flow on the receiving gravity sewer,
the flow will be redirected through a combination of force main and gravity sewer to ultimately be
served by the new regional pump station. The average daily flow is summarized as follows:
✓ Average Daily Flow (ADF) = 172,400 GPD
Additionally, as required by NCDEQ Minimum Design Criteria, peak hour factors were calculated
based on Residential Equivalent Units (REU) to be constructed within the station service area.
The NCDEQ formula as shown below was utilized in this calculation.
Peaking Factor Calculation
Service Area Population = P
Peak Factor = 18 + �P
4+�P
The peaking factor used in the pump station design is as follows:
✓ Peak Hour Factor (PHF) = 3.7
III. Pump and Force Main Sizing
Based on the average daily flows and PHF's the peak pump rate for PS No. 2 is provided below:
