NARRATIVE
SEWER SYSTEM:
These private duplex grinder pump stations and forcemain systems are designed to service
warehouse / showroom / office buildings. This permit is for the Wilmington Trade Center.
There are three (3) separate buildings with three (3) separate duplex private grinder pump
stations that will tie in to the existing 6" Public Low Pressure Forcemain that is on the West
side of US Hwy. 421. This forcemain belongs to the CFPUA.
PS #1:157,500 SF Warehouse & Office Space ADF = 6,950 GPD; PDF = 17,375 GPD
PS #2:157,500 SF Warehouse & Office Space ADF = 6,950 GPD; PDF = 17,375 GPD
PS #3:110,250 SF Warehouse & Office Space ADF = 4,900 GPD; PDF = 12,250 GPD
Each Private Pump Station will consist of a 6-foot diameter wet well, discharge piping, valve
vault, and required electrical panel and controls. The pump station reliability of the station is
per 15A NCAC 02T .0305 (h)(1)(C). A portable pump power source shall be dedicated to
backup of this station. A letter will be provided that the portable source of power is owned
or contracted for by the permittee and is compatible with the station. Telemetry is provided
at the station with remote notification if a power outage or problem occurs. A high-water
audio and visual alarm are provided.
The downstream forcemain size is 6". We are having to directional drill under US 421 with a
4" forcemain. We are able to maintain 2 fps in the 4" forcemain. The 6" forcemain is a Low
Pressure forcemain designed to accommodate multiple Pump Stations from along the 421
corridor.
There will be Private forcemain and Public forcemain in this permit.
Private Forcemain Lengths:
3" — 1892 ft
4" — 354 ft
Public Forcemain Lengths:
4" — 130 ft
6"-39ft
There are multiple conditions that occur for each pump station. Each of these pump
stations must be able to maintain 2 fps in the forcemain immediately downstream from the
pump station and overcome any Pump Stations that may also be on during operation. PS
#1 must be able to maintain 2 fps in the 4" forcemain. With that in mind, each pump station
will pump well above their required peak, in the predominant condition.
The MDC requires if practical, a minimum of two (2) cycles per hour. Due to the ADF, the
duplex pump / wet well requirements and the minimum FM requirements it is not practical to
meet the two (2) cycles per hour requirement.
This system will be served by the Cape Fear Public Utility Authority.
