NCDEQ
WILMINGTON RO
On behalf of Aqua North Carolina, Inc, we are enclosing two (2) copies of the
following documents for your review and approval regarding the above referenced
project in New Hanover County, NC:
• Application Fee ($480.00)
• Fast Track Sewer System Extension Application (FTA 04-16) (1 with original
engineers' seal and 1 copy)
• Flow Tracking/Acceptance Form (FTSE 10-18)
• Attachment A
• Certificate of Public Convenience and Necessity
• Business Corporation Annual Report
• USGS Topographic Map
• Street Level Site Map
This project includes the installation of an iron and manganese filtration system and
an associated backwash wastewater disposal pump and approximately 1,750 linear
feet of 1.5-inch PVC force main that discharges to a nearby manhole. The total
anticipated discharge volume for this project is approximately 1,790 gallons once per
week at a flow rate of 20 gpm.
It is important to note that although the 1.5-inch force main does not meet 2T
minimum size requirements, the size was selected based on achieving the minimum
self -cleansing velocity while ensuring efficient pump operation.
If you have questions or require additional information, please do not hesitate to
contact me at [phone] [e-mail].
Sincerely,
THE WOOTEN COMPANY

ATTACHMENT A
Project Description
The project includes the installation of an iron and manganese filtration system at River & Sanders Well
#8, owned and operated by Aqua North Carolina, Inc. The system will include disposal of the settled
backwash wastewater from the bottom of the backwash settling tanks to a nearby Aqua North Carolina
owned manhole. The iron and manganese filtration system will include four (4) pressure filters and two
(2) backwash water settling tanks. The pressure filters will be mounted on two (2) skids inside the
proposed building and the backwash settling tanks will be installed outside on a concrete pad.
Backwashing & Backwash Wastewater Disposal
Backwash from the filters is discharged to the backwash holding/settling tanks where it is temporarily
stored for a minimum of 3 hours to allow solids to settle. Backwash water in the holding tanks is
reintroduced to the inlet of the treatment system via a backwash recycle pump where it is blended with
the raw well water. After approximately five (5) backwashing events, the settled backwash wastewater
containing iron and manganese solids will be disposed of by pumping the wastewater from the bottom
of the cone to a manhole approximately 1,750 LF away via a 1.5-inch PVC force main. The manhole is
located just north of the intersection of River Road and Turtle Cay Drive.
The 1.5-inch force main does not meet 2T minimum size and horizontal separation requirements
referenced in Sections VIII and IX of the Fast Track Application. Although the 1.5-inch pipe is being
referred to as a force main it is important to note that this is not a typical pump station/force main
design and does not have a wet well. The size was selected based on achieving the minimum self -
cleansing velocity while ensuring efficient pump operation. Due to NCDOT pavement offset restrictions,
the 1.5-inch force main is located 5 feet off the existing water line and therefore does not meet
horizontal separation requirements. However, it is important to note the backwash wastewater being
conveyed is treated groundwater containing a low percentage of settled solids (iron and manganese)
and NOT "sewage" as defined in 15A NCAC 02T.
The well building will be equipped with a generator quick connection. However, if there was a power
outage then the whole well operation would stop and no backwash wastewater would be generated.
