NARRATIVE
US 421 FULLER BUILDINGS
3240, 3246, & 3252 US Hwy. 421 North
SEWER SYSTEM:
The private duplex grinder pump station and forcemain system is designed to service
existing office / warehouse buildings each with 15 employees and dock doors. A total of
40 LF of 2" sewer line will be needed to complete the system. The private pump station
will serve the 3 existing buildings plus 2 future buildings. It will connect to the recently
completed 8" forcemain owned by the CFPUA. The average daily design flow of the
station is 3,675 GPD. 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 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.
There are 2 separate conditions that occur at the connection point to the CFPUA
forcemain. The design condition is where the upstream pumps that connect to the
forcemain are off. This results in a very low head condition to pump into the 8"
forcemain. This condition will result in a condition of approximately 15 GPM at 36' TDH.
The second condition is with upstream pump on. The CFPUA can give us little
confidence in the pressure to overcome. Our maximum pump operating will be
approximately 9.5 GPM at 119' TDH.
The MDC requires if practical, a minimum of 2 cycles per hour. Due to the ADF and the
duplex pump / wet well requirements, it is not practical to meet the 2 cycles per hour
requirement.
Also, the MDC requires a minimum of 2 FPS in all forcemain design. Due to the
extreme conditions that the pump station must overcome, we cannot provide 2 FPS in
the desired 2" forcemain. The length of the forcemains is 40 LF. We do not
recommend downsizing the forcemain to less than 2".
A portion of the 2" forcemain in the right-of-way from the CFPUA forcemain to the gate
valve at the right-of-way shall be maintained by the CFPUA.
This system will be served by the Cape Fear Public Utility Authority

III. Certification Statement:
I Jeff Theberge, CFPUA Eng. Mgr certify to the best of my knowledge that the addition of
the volume of wastewater to be permitted in this project has been evaluated along the route to the receiving
wastewater treatment facility and that the flow from this project is not anticipated to cause any capacity
related sanitary sewer overflows or overburden any downstream pump station en route to the receiving
treatment plant under normal circumstances, given the implementation of the planned improvements
identified in the planning assessment where applicable. This analysis has been performed in accordance
with local established policies and procedures using the best available data. This certification applies to
those items listed above in Sections I and II plus all attached planning assessment addendums for which I
am the responsible party. Signature of this form certifies that the receiving collection system or treatment
works has adequate capacity to transport and treat the proposed new wastewater.
