Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 28, Block 2, Cross View Estates 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 in the area 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 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.
The test hole placed on the lot in the area of the absorption trenches and alternate site
indicate silty sand with gravel (SM). The percolation rate of the soil was determined to
be 27 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 .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 2-35' long by 3' wide by 8'
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 4' below the
surface and the total depth will be 12'. A flow splitter valve will be placed to insure even
flow to each trench. 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 northwest
Lot 28, Block 2, Cross Point Estates Subdivision
May 22, 2012
Page Two
at a 5% grade with some cross sloping from the east. The new trenches will be
constructed parallel with the contours of the slope as much as 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.

5. STATEMENT OF INSPECTION BY ENGINEER
As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based on procedures outlined
in the Certificate of On-Site Systems Approval Guidelines for this application, shows that the on-site water supply and/or wastewater
disposal system is (are) safe, functional and adequate for the number of bedrooms and type of structure indicated herein. I further verify that
based on the information obtained from the Municipality of Anchorage files and from my investigation and inspection, the on-site water supply
and/or wastewater disposal system is(are) in compliance with all applicable Municipal and State codes, ordinances,and regulations in effect at
the time of installation.
In conducting an adequacy test,I attempt to provide a thorough,conscientious engineering analysis of the system in accordance with MoA COSA
guidelines and regulations.The reported results describe the performance of the system under the conditions encountered at the time of the test,
and separation distances measured to readily identifiable features. The operational life of all wells and septic systems depend on the local soil
condition,ground water levels that may fluctuate during the year,and the water usage of the family being served by the system.These conditions
are outside the control of the evaluator of this system. All systems eventually fail and satisfactory test results do not guarantee future
performance of the system,nor do they guarantee that there are no hidden defects or encroachments.Therefore we cannot provide any warranty
for future performance, nor can vie estimate remaining life of the system.The content of this report is for the sole benefit of the owner listed
above.
