Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 9, Block 4, Majestic Valley Estates Subdivision intends to construct a
new three-bedroom home on the lot. We are therefore requesting a permit be issued
for the construction of a new well and septic system to accommodate the home. The
attached Site Plan and backup documentation identify the location and configuration of
the proposed well and septic system along with the alternate site. Also identified on the
plans are the existing wells and septic systems on surrounding lots. No conflicts exist
between the proposed septic system and well or septic systems and wells on adjacent
lots. Drainage arrows and surveyor elevations are shown on the site plan showing the
grade and direction of flow on the lot. The drainage pattern will not be changed as a
result of this project.
Two test holes were placed on the lot in the area of the absorption trench and alternate
site. The logs indicate silty gravel (GM) with sand in the zone specified for the
absorption trench. The percolation rate of the soil was determined to be 8-9 minutes
per inch. No groundwater was found during the placement of the test holes and none
was noted during the monitoring period. An application rate of .8 gallons per day per
square foot was used in the design of the absorption system. We are proposing to
place a new 1,000-gallon septic tank and a 57' long by 5' wide by 4' effective depth
absorption trench to treat and dispose of the effluent generated in the house. The
elevation of the distribution line in the absorption trench will be 2' below the surface and
the total depth will be 6'. A minimum of 3' of fill or 2" of insulation and 2' of fill will be
placed over the absorption trench and 4' over the septic tank.
The ground surface on the lot in the area of the septic system slopes to the southwest.
The new trench will be constructed parallel with the contours of the slope as much as
Lot 9, Block 4, Majestic Valley Estates Subdivision

possible in conformance with Municipal requirements. The new septic system will be
constructed a minimum of 100' from all wells and any surface water and 10' the
proposed and existing water services 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.
