Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of the subject property 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 serve the new house. The attached Site Plan and backup
documentation identify the location and configuration of the new well and septic system
and the parameters used in the design. Also identified on the plans is the location of an
existing Class C Well and the 150' protective radius along with the location of the test
holes and surrounding wells and septic systems. Existing drainage patterns are shown
and will not be altered by the development of the lot.
Two test holes were placed near the location of t~he new absorption trench an~l alterr{ate
site. These holes indicated silty gravel with approximately 1' of organic overburden.
Pemolation tests in the material resulted in rates between 30 and 60 minutes per inch.
No groundwater was found during placement of the test holes and none has been
noted during the monitoring period. We are therefore proposing to place a deep
absorption trench system with 8' of gravel beneath the distribution pipe. The total depth
of the trench will be 11'. The distribution pipe will be placed at 3' below the ground
surface.
The ground surface on the lot slopes as shown on the attached Site Plan with only
shallow slopes near the proposed septic system site. The new absorption bed will be
constructed on a fairly fiat surface in conformance with Municipal requirements and
parallel to ground contours where possible.
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.

and will not be altered by the development of the lot.
Two test holes have placed near the location of the new absorption bed and alternate
site. These holes indicate silty gravel with approximately 1' of organic overburden.
Percolation tests in the material resulted in rates between less than 30 and 60 minutes
per inch. No groundwater was found during placement of the test holes and none has'
been noted during the monitoring period. We are therefore proposing to place a deep
absorption trench system with 8' of gravel beneath the distribution pipe. The pipe will

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.
