HomeMy WebLinkAbout1993 - Septic System Inspection for sale of home TO: File - 2100 Webber Hills Road
FROM: Stephen Weckman, On-Site Systems Manager
DATE: July 9, 1993
SUBJECT: Septic System Inspection on June 7, 1993
A septic system inspection was scheduled for 2100 Webber Hills Road at the request of the
realtors with regard to the sale of the home. Prior to the on site inspection, they were informed
that the property lies within the shoreland district and is subject to the recently adopted
Shoreland Regulations, which require soil borings to identify the separation from the sewage
treatment device and the seasonally high water table as identified by mottling.
I met both realtors on the site on the morning of June 7, 1993 for the septic inspection. As we
walked across the site to the septic system, I explained the history of the septic system inspection
program and the system classification history up until this inspection. The system has been
classified as a substandard system in 1978. As it was apparently installed according to the codes
enforced at the time of installation, it is not an illegal system such as a cesspool, and was not
observed to be discharging effluent to the surface.
Once the drainfield trenches had been identified, I took soil samples while I explained the
DNR's new requirement of the 3' separation between the sewage treatment device and the
seasonally high water table as defined by mottling.
After examining each of the samples, they were passed on to the two realtors to examine and
I pointed out examples of mottled soil. The first soil boring revealed prominent mottling at 4'
and I explained what is considered prominent mottling. I then showed them my soil probe,
which identified the first trench. The top of the trenches was found to be 2' below the surface
and the trench bottom would then be at least 36" deep. I explained then that the system only
had a 6" separation from the system to the water table and is clearly nonconforming, requiring
replacement within one year. A second soil boring was then performed to confirm the result of
the initial boring. This second soil boring revealed mottling at 30" with the trench depth at 36"
still. This portion of the system would therefore be within the water table.
As we were leaving the site, I asked if they had any questions. There were no questions and
I left the site.
