Septic system design
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 2-bedroom home on the property, so we are
submitting this permit application for the construction of a new septic system. The attached site
plan identifies the location of the home as well as the proposed 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 system will be sized for 3-bedrooms, to be conservative.
The ground surface on the lot slopes towards the street. The system is proposed in a flatter area
near the driveway. There are no slopes greater than 25% within 50 ’ downhill of the system.
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.
Adjacent properties are all served by a community water system, and the proposed connection to
this lot is also shown. The new septic system will be a minimum of 100’ from any surface water
and more than 5’ away from the septic tank. The alternate site is located more than 1 2’ 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
