Dear Mr. Burton,
On June 10, 1994, I arrived(
allegedly failed. 429 Gilbert Street for the purpose of a site
evaluation to install a septic system to replace the existing seepage pit which had
Upon arrival, I was asked to look at the existing pit to corroborate the alleged
failure. My inspection showed than the pit was indeed leaching liquid, as it
should and that the liquid level was approximately 5" below the outlet invert of
the sewer pipe.
I was then directed to a location where the home inspector claimed that a pool of
water on the ground was due to failure of the seepage pit. Plainly visible from
that location is a roof drain pipe. The flow is directed to the low area where the
puddling occurred. At that location the ground is bare indicating standing surface
water. If it was failure of the seepage pit, there would exist a luxuriant growth of
grass from the cover of the pit down the slope to the puddling area.
My soil examination showed that a high groundwater condition exist. This is
exhibited by the rust mottling in the soil and by the shallow root growth of trees.
High ground water is a typical condition of this type of soil. I estimate ground
water at this site to be approximately 52" below the surface of the ground. This is
demonstrated by an observation, a groundwater adjustment factor, and the
location of rust mottles in the soil. Enclosed is a copy of the site evaluation
report demonstrating this.
Since the sewer pipe is approximately 30" below the surface of the ground any
high ground water would affect the appearance of the pit, but not necessarily the
function of the pit (due to hydraulic pressure).
If I can be of further assistance, please do not hesitate to contact me.
