Your request for a waiver of the required 100 feet horizontal separation from the
absorption field and septic tank on Lot 9 to the private well on Lot 10 has been approved. The
approved separation distance is 91.0 feet for the field and 88' for the tank.
This waiver approval applies to the existing absorption field and septic tank only. Any future

Waiver request — well to septic tank and field
Dear On -Site Services Engineer:
At some point after the well driller installed the well on this property, the contractor measured the
distance to the septic field on Lot 9 to the south and discovered that there wasn't 100' separation.
The surveyor verified that the well encroaches on both the septic tank and the field.
Both the tank and the field are downhill from the well at a slope of about 5.5%. There is no
possibility of effluent running out of the tank and contaminating the well head. Any overflow of
effluent would flow downhill away from the well, toward Lot 8. In addition, the area around the
well head has been graded to flow away from the casing, per code.
Soils in the area of the septic system on Lot 9 were recorded as SM down to 19', and perked at a
rate of 6 min/in. Effluent in the trench will tend to flow down through the soils rather than spread
out, and will achieve sufficient treatment through the soils as it spreads down and outward.
There is no threat of contamination of the well head due to the proximity of the tank and field. For
this reason, we request a waiver be issued for the 88' separation to the tank and the 91' separation
to the trench.
Sincerely,
Benjamin

Septic system design
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 4-bedroom home on this currently-vacant property.
The attached site plan identifies the location of the home as well as the proposed well, septic
location and alternate site.
The ground surface on the lot slopes moderately toward the southwest at between 5 -10% grade.
There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate
site. Contours are shown on the site plan showing the grade and direction of flow. The new trench
will be constructed parallel to the slope as much as possible.
The existing test hole has groundwater monitoring, but limited percolation testing. In particular,
the test hole shows an unperked ML layer from 5’ to about 12’ down. Additional soils information
provided in the full soils report calls this layer “Sandy Silt” and includes some gravel up to 2” in
size. An additional test hole and perk test was completed, demonstrating that this layer was not
impermeable. While the system will not be installed in this layer, we have chosen to use a
conservative percolation rate (1.0 for Advanced Treatment) in the case that some of these soils are
found shallower and at the elevation of the receiving soils. The majority of the trench will be in
soils that perked under 30 min/in.
Stormwater drainage will not impact this septic system. The new system will be a minimum of
100’ from all wells and surface water, and more than 5’ away from the septic tank. The alternate
site is located more than 16’ away. Please refer to the attached test hole logs, plan and profile pages
for the septic design. If this design is followed, there will be no adverse impacts to adjacent
properties.
Sincerely,
Benjamin Schiller, PE
