Septic system design
Dear On -Site Services Engineer:
The owner of the above lot is replacing his septic system, so we are submitting this permit
application for the construction of a new one. The attached site plan identifies the location of the
home as well as the proposed septic location and existing well.. 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 this site slopes down toward the back of the lot. There are no slopes greater
than 25% within 50 feet downslope of either the primary or alternate site. Contour lines are shown
on the site plan. Storrnwater drainage will not impact this septic system. The new trench will be
constructed parallel to the slope as much as possible.
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.
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
