Well and Septic System Design
Dear On-Site Services Engineer:
The owner of the above lot intends to build a 4-bedroom home on the property. We are submitting
this application for a permit to construct a new well and septic system. The attached site plan
identifies the location of the home and 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 moderately to the southwest at grades from 5% to 15%.
Drainage arrows are shown on the site plan indicating the grade and direction of flow. Storm water
drainage will not impact this septic system. The new trenches will be constructed parallel to the
slope as much as possible. The test hole completed for the lot will be deepened to 17’ prior to
construction to verify the lack of bedrock or impermeable soil layers.
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 16’ away.
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, P.E.
