Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The absorption system on the subject lot has failed and must be replaced. We are
therefore requesting a permit be issued for the upgrade of the septic system to
accommodate the proposed 10-bedroom home on the lot. The attached Site Plan and
backup documentation identify the location and configuration of the existing and
proposed septic systems. The existing concrete septic tanks will be decommissioned in
accordance with Municipal Code. In addition, the existing absorption trench system will
be decommissioned in accordance with Municipal Code. Also identified on the plans
are the locations of the existing Class C well on Lot 3 to the north which serves this lot.
No conflicts exist between the proposed septic system and the wells on adjacent lots.
Drainage arrows are shown indicating the current drainage patterns. The ground
surface in the area of the proposed trench is virtually flat. The drainage patterns will be
maintained after construction.
The test holes placed on the lot indicated Silty Gravel with Sand (GM) in the absorption
zone of the trench. The percolation rate was determined to be between 6 and 15
minutes per inch. No groundwater was encountered during the placement of the test
holes and none has developed to date. We have designed the new trench with an
application rate of .8 gallons per day per square foot. We are proposing to place a new
3,000 gallon septic tank along with 2-79' long trenches by 3' wide with a 6' effective
depth. The total depth of the system will be 10' with the distribution line at 4' below the
existing surface. A flow splitter valve will be placed to insure even flow to each trench.
Insulation 4" thick will be placed over the sewer service line under the driveway.
The ground surface on the lot in the area of the new trenches is flat. The trenches will
Lot 4, Block 2, Fire Lake No. 2
April 26, 2017
Page Two
be placed parallel to the contours of the ground as much as possible and 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:
1. 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.
2. 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.
3. 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.
4. 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,

Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The absorption system on the subject lot has failed and must be replaced. We are
therefore requesting a permit be issued for the upgrade of the septic system to
accommodate the seven -bedroom home on the lot. The attached Site Plan and backup
documentation identify the location and configuration of the existing and proposed
septic systems. The existing concrete septic tanks will be uncovered, inspected and
verified suitable for continued use. The absorption trench system will be
decommissioned in accordance with Municipal Code. Also identified on the plans are
the locations of the existing Class C well on Lot 3 to the north which serves this lot. No
conflicts exist between the proposed septic system and the wells on adjacent lots.
Drainage arrows are shown indicating the current drainage patterns. The ground
surface in the area of the proposed trench is virtually flat. The drainage patterns will be
maintained after construction.
The test hole placed on the lot indicated Silty Sand with Gravel (SM) in the absorption
zone of the trench. The percolation rate was determined to be between 6 and 15
minutes per inch. No groundwater was encountered during the placement of the test
hole and none has developed to date. We have designed the new trench with an
application rate of .8 gallons per day per square foot. We are proposing to place a
1,000 gallon septic tank in line with the existing concrete tanks. In the event the
concrete tanks are found unacceptable a new 2,500 gallon septic tank will be installed.
In addition to the new septic tank 2-55' long trenches by 3' wide with a 6' effective depth
will also be constructed. The total depth of the system will be 10' with the distribution
line at 4' below the existing surface. A new test hole will be placed prior to construction
to verify the soils are consistent in the area and the alternate site can be constructed

where it is currently proposed. Insulation 4" thick will be placed over the sewer service

The ground surface on the lot in the area of the new trench is flat. The trench will be
placed parallel to the contours of the ground as much as possible and 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

in the area or those to be constructed in the future.
2. The system, if constructed as designed, will have no adverse impact on existing

3. 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.
4. The system, if constructed as designed, will have no adverse impact on drainage
patterns in the area. The current drainage pattern will be maintained.
