On Sel te.iber 22-2-4s 1983 six percolation holes were tested
and 3 scil borings taken on the above property to determine 2
drainfield sites, a primary and an alternate site. Testing was
done in accordance with the provisions of Individus'. Sewage
Treatment Systems Standards (WPC-40).
The percolation holes were dug 6 inches in diameter `c a
42 inch depth while the soil borings were dug 6 inches in di. -
meter to the 4 foot depth and 3 inches in diamter to the re-
maining depth.
Very good loamy soils were encountered just below the
proposed house location near the top of the knoll which would
probably allow gravity flow from the house. The average per-
colation rate of Z2.1 minutes per inch and lack of a high
water table would allow a standard system to be constructed
on either site.
Once the house size and location are known, a design for
the system should be made. If any other information is needed
in the meantime, please contact me.
Sincerely,
PERCOR, INC.
