Septic system design
Dear On-Site Services Engineer:
The owner of the above lot intends to build a new 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. 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 moderately from the back of the lot at about
a 10-15% slope. 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 trenches will be located uphill from the house, but the contractor is confident that he can install
them deeper to avoid putting in a lift station. We have specified on the septic section that the
maximum depth is 12’ to ensure separation to impermeables.
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 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
