Subject: Lot 4, Sandy Acres Subdivision
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of Lot 4, Sandy Acres 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
locations of wells and septic systems on the surrounding lots. No conflicts exist
between the proposed septic system and those on adjacent lots. Drainage arrows are
shown indicating the surface slope of the property in the area of the new septic system.
Test holes were placed on the lot in the area of the absorption trench and alternate site,
which indicated a silty sand with some gravel (SM/SP) material.. The percolation rate
of the materials was determined to be 17 to 60 minutes per inch. No groundwater was
found during the placement of the test holes, but was noted at 13' and 14' during the
monitoring period. An application rate of .45 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 2-56' long by 3' wide by 6' 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 2' below the surface and the total depth will be 8'. A
minimum of 3' of fill will be placed over the absorption trenches and 4' over the septic
tank. A flow splitter valve will be installed to insure even flow to each trench.
The ground surface on the lot in the area of the septic system slopes gently to the
northwest. The new trenches will be constructed parallel with 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
Lot 4, Sandy Acres

proposed and existing water services in the area.
If the system is constructed in accordance with our design the following statements
apply:
1. 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.
2. 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.
3. 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.
4. 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, n� "

ON-SITE WASTEWATER DISPOSAL SYSTEM
CONSTRUCTION AND MATERIAL SPECIFICATIONS
SUBJECT: LOT 4, SANDY ACRES SUBDIVISION
GENERAL:
The scope of this project includes the procurement and placement of a new
1,250 -gallon septic tank at the location shown on the Site Plan. Work also
includes the construction of 2 new 56' long X 3' wide X 6' effective depth
absorption trenches at the location also shown on the Site Plan. The
distribution line in the trench will be placed at 2' below the existing ground
surface. Total depth of the trench will be 8' below the existing ground
surface. The new absorption trenches and septic tank must be placed a
minimum of 100' from all private wells and any surface water in the area and
10' from the water service line proposed for the lot. A minimum of 3' of cover
is required over the absorption trench and 4' of cover over the septic tank. A
flow splitter valve must be placed to insure even flow from each trench.
2. Construction shall be in accordance with the approved site plan, design
drawings, Municipal Permit with any special provisions or conditions, and all
applicable State and Municipal Wastewater Disposal Regulations.
3. 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. The Contractor must also verify the location of wells in the
area and assure that the separation distances are met.
4. 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.
5. 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
A new 1,250 -gallon septic tank must be procured from an approved source
and installed at the location shown.
2. 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.
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:
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.
4. Monitor tubes must be 4" in diameter and installed at the locations shown on
the design. The portion below ground must be perforated.
5. 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.
6. 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.
7. Grade area surrounding the absorption trench to drain away.
8. 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.

or A.B.S. (perforated and solid).
3. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow
Chemical Co. Styrofoam HI or equal).
4. Septic tank inlets and outlets shall be fitted with watertight couplings
(Caulder, Fernco, or equal).
5. A permeable geotextile fabric (Typar, Mirafi or equal) must be installed
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.
Contractor shall provide a copy of all field survey layout and construction notes
for use in preparing the certified as -built of the completed system.

MEMORANDUM
DATE: November 30, 2005
TO: Julie Makela, P.E.
FROM: Mike Anderson, P.E.
SUBJECT: Lot 4, Sandy Acres Subdivision
Well and Septic System Permit
Attached ;is the modified area map showing wells and septic systems surrounding Lot
4, Sandy Acres Subdivision. A Class A Well is in service on the property immediately to
the west. The well is located more than 200' from the property lines of Lot 4. No other
wells or septic systems in the area conflict with the proposed well or septic system for
this lot.
The proposed absorption trench system and alternate site are located slightly outside
the 30' radius of the test hole on the lot. This test hole was completed during the
subdivision phase of the project and was the only area where soil absorption
characteristics were slower than 15 minutes per inch. We anticipate that actual
conditions found surrounding this test hole will yield soils with much better absorptive
characteristics. We therefore request that a condition be placed on the permit requiring
the submittal of an additional test hole and percolation testing to verify soil conditions.
This work can be accomplished at the time of the construction of the system and will
result in a substantial monetary saving to the owner of the property.
Please let me know if you have further questions.
