Cover Letter, wastewater flow calculations and project narrative for NCDEQ, Division of water
Quality Fast -Track Sewer System extension application.
Proiect Narrative:
The Bowman Village, Phase N 1 & N2 project consists of a new 49 lot subdivision (which is part
of a larger 177 lot subdivision) with associated public roadways, utilities, open space, drives,
parking, etc. being built on two parcels of land totaling 68.64 acres. Future phases will be
submitted at a later date. The homes will be a mix of three- and four -bedroom models. The site
is located in the vicinity of 7117 Bowman Road, Mebane North Carolina with this portion of the
site being north of Bowman road. It can be identified with PIN# 9824-74-5328 & 9824-73-6163.
The development of this subdivision will require a public sewer extension to tie into the City of
Mebane sewer system. This portion of the gravity sewer extension will consist of 16 new
manholes and 1,107.70 If of 8" SDR-35, PVC and 1,157.51 If of 8" ductile iron pipe (DIP). The
new sewer main will tie into a City of Mebane 8" ductile iron sewer main at a manhole.
Wastewater Flows:
-4 bedroom residential homes = 80* gal Ions.-'day/bedroom with a 160* gallons/day min.
(Exact mix unknown, calculated at highest possible volume)
* See attached Flow Reduction Approval for the City of Mebane

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 indicates acceptance of this wastewater flow.

Subject: Mebane WWTP (NC0021474)
Flow Reduction Request
Alamance County
Dear Mr. Wilson:
Dee Freeman
Secretary
On February 14, 2011, the Pretreatment, Emergency Response and Collection System (PERCS) Unit of
the Division of Water Quality received a flow reduction request for connections to the City of Mebane WWTP.
The letter requests an allowable flow rate of 80 gallons per day (gpd) per bedroom based on the evaluated data
As daily WWTP data is not representative of the project area, the DMR data from the City of Mebane
WWTP (NC0021474) from January 2009 through December 2009 was evaluated to determine the peak sewage
month. The highest flow month was December 2009. Daily wastewater flows were recorded downstream of
the Holly Ridge Subdivision during December 2010. This data was reviewed by PERCS and Regional Office
staff.
Based on the data, the Division hereby grants a reduction in flow to 80 gpd/bedroom (minimum of 160
gpd for 1 and 2 bedroom residences) for sewer extension permits issued tributary to the City of Mebane
WWTP.
Regardless of the adiusted design daily wastewater flow rate, at no time shall the wastewater flows
exceed the effluent limits defined in the NPDES permit for the treatment facility or exceed the capacily of the
sewers downstream of any new sewer extension or service connection(s).
If you have any questions or comments regarding this matter, please contact Sarah Morrison at (919)
807-6310, or email [[e-mail]] or Deborah Gore, Unit Supervisor at [phone], or

Erin,
I've attached the relevant plan and profile drawing so that you can see what's going on with regard to
those checked boxes on the application.
We are crossing under a stream with a sewer bore at the indicated location. Where the sewer makes a
perpendicular crossing of the stream we pass between two small wetland areas at a distance of less
than 50 feet from both. To mitigate this we are:
• Performing a perpendicular crossing, not paralleling the stream or the wetlands.
• Boring under the creek with an encasement pipe. The bore pit is outside of the Zone 1
stream buffer.
• Constructing the line between MH-Al and EX MH-3 to water main standards with Class
50 pipe and testing to 150 psi, per the Minimum Design Criteria for Gravity Sewer
document.
• The pipe at the crossing itself within the encasement is restrained joint pipe, again per
the Minimum Design Criteria.
Also, we did check "no" on the high priority line question as there is no aerial sewer, nor are we
contacting the stream. Again, the crossing is perpendicular to the stream, and keeps our disturbance
outside of the sensitive stream bank areas and places all of the appropriate erosion control measures
on the perimeter of the disturbed area. As you can see there are no pipes parallel to the stream that
are subject to erosion.
Does that answer your questions? If not feel free to call our office or we can set up a zoom meeting to
discuss the design.
Sincerely,

Good Morning,
We are reviewing the subject application and have the following questions:
Item IX.2 is check "no" for meeting wetland separation requirements. Please explain.
Item IX.6 is checked "no" for high priority lines. Please confirm that no lines in this project will be aerial
lines, contacting surface waters, or will be positioned parallel to streambanks that are subject to
erosion.
Thank you,
