Septic system design
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 4-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.
The ground surface on the lot slopes fairly uniformly to the southwest at between 15 and 20%,
with a few shallower or steeper areas. 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.
We have designed this system using the soils information available in the subdivision septic
feasibility files. Along with this, we are specifying that a confirmation test hole must be dug at the
time of installation to confirm that the soils are consistent.
Wells on this and adjacent lots are shown. No conflicts exist between this proposed system and
any other well or septic system, whether on this lot or adjacent lots. 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 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
