Lot 2C-2, Hanks Subdivision
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 2C-2, Hanks Subdivision intends to construct a new four-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 ground surface contours are shown on the site plan indicating the grade and
direction of flow on the lot. The drainage pattern will not be changed as a result of this
project.
A test hole was placed on the lot in the area of the absorption trenches and altemate
site. The log indicates silty sand (SM) in the zone specified for the absorption trench.
The pemolation rate of the soil was determined to be 24 minutes per inch. No
groundwater was found during the placement of the test hole and none developed
during the monitoring period. An application rate of .6 gallons per day per square foot
was used in the design of the absorption system. We are proposing to place a new
1,250-gallon septic tank and 2-50' long by 5' wide by 4' effective depth absorption
trenches to treat and dispose of the effluent generated in the house. The elevation of
the distribution line in the absorption trench will be 3' below the surface and the total
depth will be 7'. 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 east. The
new trenches will be constructed parallel with the contours of the slope as much as
Lot 2C-2, Hanks Subdivision
June 8, 2016
Page Two
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.
