Septic system design
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 3-bedroom home on the property, so we are
submitting this permit application for the construction of a new well and septic system. The
attached site plan identifies the location of the home as well as the proposed well, septic location
and alternate site. No conflicts exist between this proposed system and any other well or septic
system, whether on this lot or adjacent lots.
The ground surface on the lot slopes toward the south side of the lot, and the septic trenches are
aligned along the contours in this area. There is a short section of steeper slopes (less than 25%)
near that corner, but the trenches are below that. 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. Stormwater drainage will not impact this septic system. The new
trench will be constructed parallel to the slope as much as possible.
The test hole done previously was placed in an area that is now covered by the home site. We have
used that test hole for our design, while specifying that a new test hole must be done prior to
construction in the area that the septic will end up in.
Wells on this and adjacent lots are shown. 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 6’ away. Please refer to the attached test hole log, 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
