Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 12, Block 2, Rockhill Subdivision Phase II intends to construct a new
five-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 proposed home. 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 are the location of the well on the lot and the test hole locations along with
wells and septic systems located on nearby lots. Existing drainage patterns are
shown and will not be altered by the development of the lot.
The test holes placed near the location of the proposed absorption trench indicate clean
gravel and sand with varying amounts of silt. The pemolation test completed in the
material resulted in rates between 7 and 9 minutes per inch. No groundwater was
found during the placement of the test holes and none was noted during the monitoring
period,. We are therefore proposing to place a 3' wide deep absorption trench system
with8 of gravel beneath the distribution pipe. The total depth of the trench will be 10'.
The distribution pipe will be placed at 2' below the ground surface to provide sufficient
drop from the septic tank to the absorption trench. The total length of the new
absorption trench will be 60'.
The ground surface on the lot slopes as shown on the attached Site Plan with very little
to no slope near the proposed septic system site. The new absorption trench will be
constructed on a faidy fiat surface in conformance with Municipal requirements and
parallel to ground contours where possible. All components of the new septic system
will be constructed a minimum of 100' from wells on the lot.
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.
Lot 12, Block 2, Rockhill Subdivision
April 15, 2002
Page Two
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.

location of all lot lines.
Unless specifically agreed otherwise, the contractor shall be
responsible for final grading areas subsequently depressed from soil
settling. Property owner shall be responsible for revegetation of
affected areas unless specifically agreed otherwise. '
Contractors installing wastewater disposal systems must be certified
by the Municipal Department of Health and Human Services for
system installations. Owners installing their own systems must receive
prior approval from D.H.H.S. before beginning system installation.
SEPTIC TANK INSTALLATION
1. A new 1,500-gallon septic tank must be procured from an approved
source and installed at the location shown.
A septic tank is to be constructed by a certified septic tank
manufacturer. Construction shall include two 4" cleanouts for pumping
access.

shifting of the tank.
4. All standpipes on the septic tank shall extend a minimum of 12 inches
above final grade.
5. Tanks installed without 4' of cover shall have a minimum of 2" of direct
burial insulation.

Page 2 of 3
A foundation cleanout shall be installed one to four feet from the
building foundation. Two cleanouts are required between the tank and
the drainfield.
Final grading over the tank shall be such that a positive slope exists
away from the septic tank.
DRAINFIELD CONSTRUCTION:
1. The drainfield shall be constructed to the dimensions shown on the
design, The bottom of the trench shall be within 2" of level.
2. Distribution piping must be placed level with perforations down atop a
level bed of drainfield rock. Rock should then be placed over the pipe
to provide a minimum of 2" of cover.
3. A silt barrier or geotextile fabric must be placed between the drainfield
rock and the natural soil backfill.
J
o
Monitor tubes must be 4" in diameter and installed at the locations
shown on the design. The portion below ground must be perforated.
Contractor shall vedfy the septic tank and drainfield are a minimum
100' away from any private water wells in the area, 150' from a Class
"C" Well or 200' from any community well.
Direct bury insulation must be placed over the distribution system if
less than 3' of backfill depth is available. Finish grade over the trench
must be mounded to prevent settlement or depressions.
Grade area surrounding the absorption trench to drain away.
A minimum 2' of accepting soil is required below the drainfield rock for
a 5' wide trench. Contractor shall verify this condition pdor to
placement of the rock. All pockets of unacceptable materials must be
removed and replaced.
MATERIAL SPECIFICATIONS:
1. Septic tanks must be constructed by a municipally approved septic
tank manufacturer,
The following pipe materials are approved for use in septic system
installations in the Municipality of Anchorage:
Cast Iron (perforated and solid), ASTM D3034 or P.V.C. (perforated
