Well and Septic System Design
Dear On-Site Services Engineer:
The owner of the above lot intends to provide sewer service to an existing 4-bedroom home on
the property. 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 and the proposed well and
septic location and alternate site. No conflicts exist between this proposed well and system and
any other well or septic system on this lot or adjacent lots.
The ground surface on the lot slopes to the west at an approximate 20% grade. There may be slopes
greater than 25% for short distances within 50 feet downslope of either the primary or alternate
site. The absorption trenches have been designed to comply with the steep slope provisions of the
Municipal Code. The distribution lines are set at 3.5’ below the surface and no surface disturbance
will occur within 50’ down grade from the absorption trenches. Ground contours are shown on the
site plan indicating 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 new system will be a minimum of 100’ from all wells and 100’ from surface water and more
than 5’ from the septic tank.
Please refer to the attached test hole logs and plan and profile sheets for the septic design. If this
design is followed, there will be no adverse impacts to adjacent properties.
Sincerely,
Michael E. Anderson, PE
