Averasboro Battlefield (1.5 Acres)

Dear Mr. Lee,
A site investigation was conducted for the above referenced property which is located on
the western side of NC 82, Duke Township, Harnett County, North Carolina. The purpose of the
investigation was to determine the ability of this lot to support a subsurface sewage waste
disposal system and 100 % repair area for an additional bathroom/ comfort station. This report
represents my professional opinion but does not guarantee or represent permit approval for any
lot by the local Health Department.
Water usage data have been obtained from the Harnett County Department of Public
Utilities (copy attached). For the period of December 2006 through October 2009 these data
indicate an average daily use of 22.16 gallons. However, in February 2007 it is believed that a
leak occurred in the building, and an average of 47.8 gallons per day was recorded that month.
In March 2008, data show an average of 40 gallons per day was used. The owners are not aware
of a leak during that period. Also, in June 2009, 950 gallons were used for an average daily
consumption of 30.6 gallons. We believe this number, 30.6 gallons per day, is a good
representation of the peak flows that can be expected from this facility. Most of the activities at
the battlefield are oriented to the warmer months, and therefore collection of daily readings at
this time of year (winter) would not be representative of actual use. With expectations of
increasing flows in the future due to more visitors to the museum, this septic proposal utilizes a
daily flow of 160 gallons. It is our understanding that during special events held throughout the
year the bathrooms will be locked and portable toilets will be utilized.
A soil investigation was conducted and a significant amount of provisionally suitable
soils for subsurface sewage waste disposal was observed (see attached map). The provisionally
suitable soils exhibit a friable sandy clay loam subsoil with suitable structure and appear
adequate to support long term acceptance rate of 0.4 gal/day/sgft. Soil wetness condition in the
form of two chroma mottles were observed in the 24 to 30 inch zone below surface.

The initial septic system is proposed as a gravity driven system to two 50ft long, 25%-
reduction type drainlines (such as EZ Flow or chamber). The repair system is proposed as the
same. Due to soil wetness conditions in the 24 to 30 inch zone below surface, both systems are
required to be installed ultra shallow. This requirement will necessitate the addition of at least 6
inches of topsoil to completely cover the system. Additional topsoil, up to approximately one
foot of cover, is advisable but not required. A septic system layout and supporting information
are attached to this report.
The septic system has been demonstrated with various colored pin flags that are located
on the lot. It is important that you do not disturb the septic system area. It is recommended that
a staked line or protective fence be placed around the system prior to construction to eliminate
any potential damage to the soil or the layout of the system.
A curtain drain above the septic system is recommended. The curtain drain should be
installed two and one-half to three feet deep to intercept subsurface water moving laterally
through the soil toward the drainfield. A swale and berm along the top edge of the curtain drain
should also be installed to catch and divert surface water. At the road, water from the curtain
drain should be conveyed by solid pipe just inside the property line and outlet at the stream. See
the attached curtain drain schematic for additional detail.
Precautions should be taken to prevent vehicular traffic over the septic system and repair
area. Equipment stored in the barn should be transported around the septic system area using a
ten-foot wide easement located along the eastern property line or taken around the northern end
of the barn and out the back.
The site is serviced by public water supply from Harnett County Public Utilities. The
existing well on the northern end of the museum building will need to be abandoned to allow
setbacks from the new septic system. An application for well abandonment is attached.
Please forward this report to Harnett County when applying for a permit. I appreciate the
opportunity to provide this service and hope to be allowed to assist you again in the future. If
you have any questions or need additional information, please contact me at your convenience.
