Reference: Final Report for Comprehensive Soil Investigation
Kinnis Creek Subdivision Section 1 – Lots 20A and 20B
Dear Mr. Sandhar,
A comprehensive soil investigation has been conducted at the above referenced property,
located at 25 Kinnis Creek Drive (SR 1481) in the Black River Township of Harnett County,
North Carolina. The purpose of the investigation was to determine the ability of each lot to
support a subsurface sewage waste disposal system and repair area for a typical three-bedroom
home. All soil ratings and determinations were made in accordance with "Laws and Rules for
Sewage Treatment and Disposal Systems, 15A NCAC 18A .1900". It is our understanding that
individual septic systems and public water supplies will be utilized at this site. The maximum
house footprint used for this evaluation was 50 X 50 feet. Wetlands were not observed.
Lot 20B is dominated by provisionally suitable soils for subsurface sewage waste
disposal. These provisionally suitable soils were observed to be firm sandy clay loams to greater
than 32 inches and appear adequate to support long term acceptance rates of 0.3 to 0.4
gal/day/sqft. It appears that the soils on this lot are adequate to support a conventional septic
system and repair area for one three bedroom residence.
Lot 20A has an existing residence with an existing septic system that appeared to be
functioning properly on the day of the investigation. However, the new lot line crosses the
existing drainfield. The septic permit issued by the Harnett County Health Department (Permit #
09355) indicates the existing septic system utilizes a 1000 gallon septic tank and effluent is
distribution by gravity to three 100-foot long conventional drainlines installed with 24 inch
trench depths. It is recommended that the drainfield be modified by cutting the existing lines
short –to 60 feet—and adding additional drainline. Two 60-foot long conventional drainlines
will need to be added, one on each side of the existing drainfield. The new drainlines should be
installed off contour, parallel to the existing lines, with a variable trench depth at 18 to 24 inches
below surface. A new distribution box may need to be set to distribute effluent to the five lines of
the modified drainfield. The modified system will utilize gravity distribution to distribute
effluent to five 60-foot conventional drainlines and have a corresponding long term application
rate of 0.4 gal/day/ft2. A soil investigation was conducted and it appears that an adequate
amount of provisionally suitable soil exists on this lot to 100 % repair the system if it should fail.
