Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The existing absorption bed on the subject lot has failed and must be replaced prior to
the issuance of a Certificate of On Site System Approval (COSA). We are therefore
requesting a permit be issued for the upgrade of the septic system to accommodate the
four-bedroom home on the lot, The attached Site Plan and backup documentation
identify the location and configuration of the existing and proposed septic system. The
existing Septic Tank will be uncovered, inspected and verified suitable for continued
use. The existing absorption bed will be left intact and tied to the new system with a
flow diverter valve. Also identified on the plans are the locations of the existing well on
this and adjacent lots and adjacent septic systems. No conflicts exist between the
proposed septic system and the wells on this or adjacent lots. Protective radii are
shown to the adjacent wells. Drainage arrows are shown indicating the current
drainage patterns. The drainage patterns will be maintained after construction.
The test hole placed on the lot indicated Silty Gravel with Sand (GM/GP) to a depth of
12'. Groundwater was encountered at 10' below the surface. The percolation rate in
the GM soil lense was determined to be less than 5 minutes per inch. We have
designed the new trench with an application rate of 1.2 gallons per day per square foot.
We are proposing to place 2-35' long by 5' wide absorption trenches with a 2' effective
depth to remain a minimum of 4' above the projected water table. The total depth of
the system will be 5' with the distribution line at 3' below the existing surface. A flow
splitter valve will be placed to insure even flow to each trench.
The ground surface on the lot is virtually flat in the area of the absorption trenches. The
trenches will be placed parallel to the contours of the ground as much as possible and
Tract 10C, Iliamna Acres

in conformance with design criteria. A minimum of 100' will be maintained between all
components of the septic system and the proposed well and from any surface water in
the area.
If the system is constructed in accordance with our design the following statements
apply:
The system, if constructed as designed, will have no adverse impact on the wells
in the area or those to be constructed in the future.
The system, if constructed as designed, will have no adverse impact on existing
septic systems in the area or those to be constructed in the future.
The system, if constructed as designed, will have no adverse impact on reserve
space, either surface or subsurface, on any lots located in the area.
The system, if constructed as designed, will have no adverse impact on drainage
patterns in the area. The current drainage pattern will be maintained.
Sincerely,
Michael E. Anderson, P.E.
