Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 12, Block 5, Knik View Estates Subdivision intends to construct a four-
bedroom home on the lot. We are therefore requesting a permit be issued for the
construction of a new septic system to serve the proposed home. The attached Site
Plan and backup documentation identify the location and configuration of the new and
alternate septic system and the parameters used in the design. Also identified on the
plans is the test hole location and the locations of the existing systems on adjacent lots.
The subdivision is served by a Class A water system and the approximate locations of
the water service lines are shown. Drainage arrows are also shown and current
drainage patterns will be maintained after construction.
The test holes placed near the location of the proposed and alternate absorption
trenches indicated well to poorly graded sand with gravel and varying amounts of silt
and a percolation rate of between 1 and 2 minutes per inch. No groundwater was
found during the excavation and none was noted during the ensuing monitoring period.
We are therefore proposing to construct a 5' wide absorption trench system with 4' of
drainfield rock beneath the distribution pipe. That pipe will be placed at 3.5' below the
surface with a total depth of 7.5'. The total length of the trench will be 50'.
The ground surface on the lot slopes as shown on the attached Site Plan with fairly
shallow to no slope in the area of the new absorption trench. The new septic tank and
absorption trenches will be constructed in a fairly shallow surface slope area behind the
proposed house in conformance with Municipal requirements and parallel to ground
contours where possible. All components of the new trench will be constructed a
minimum of 200' from the well serving the community water system. The system will
also be constructed a minimum of 100' from any surface water in the area and 10' from
the water service line.
If the system is constructed in accordance with our design the following statements
apply:
Ldt 12, Block 5, Knik View Estates
August 15, 2002
Page Two
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.

absorption trench also shown on the Site Plan. The total depth of the
trench will be 7.5' below existing ground and the distribution pipe will
be placed at 3.5' below the surface. All components of the septic tank
and absorption trench must be constructed a minimum of 10' from the
water service line on this lot. A minimum of 4' of fill must be placed
atop the septic tank and 3' of fill atop the absorption trench. In lieu of
fill 2" of direct bury insulation may be placed with 2' of fill atop the
insulation.
Construction shall be in accordance with the approved site plan,
design drawings, Municipal Permit with any special provisions or
conditions, and ali applicable State and Municipal Wastewater
Disposal Regulations.
The Contractor shall be responsible for obtaining all underground utility
locates and for the layout of the septic system and verification of the
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. The 1,250-gallon Septic tank must be procured from an approved
septic tank manufacturer 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.
3. The septic tank shall be sufficiently bedded to prevent settling or
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.
Lot 12, Block 5, Knik View Estates
August 15, 2002
Page 2 of 2
6. A foundation cleanout shall be installed one to four feet from the
building foundation. Two cleanouts are required between the tank and
the drainfield.
7. Final grading over the tank shall be such that a positive slope exists
away from the septic tank.
DRAINFIELD CONSTRUCTION:
The drainfield shall be constructed to the dimensions shown on the
design. The bottom of the trench shall be within 2" of level.
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.
A silt barrier or geotextile fabric must be placed between the drainfield
rock and the natural soil backfill.
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 verify 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 prior 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°VoC. (perforated
and solid), ASTM F810 or H.D.P.E. (perforated, but not Solid) and
ASTM D2662 or A.B.S. (perforated and solid).

between the final drain rock layer and the native soil layer.
6. All drain rock shall be .5" to 2.5" in diameter with less than 3% passing
the #200 sieve.
INSPECTIONS:
Municipal Ordinance requires a minimum of two inspections. These
inspections must be conducted under the supervision of a professional
engineer registered in the State of Alaska. The first inspection must be
conducted after the excavation of trenches, beds or pits and before the
installation of any gravel. A septic tank may be set in place, but may not
be backfilled.
The second inspection must be conducted after the placement of the
geotextile fabric, gravel, distribution piping, standpipes, cleanouts and
insulation. No backfill should be in place at the time of inspection.
