Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The owner of the South''/: of Lot 18, Section 10, T1 2N, R4W 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 serve the home. The attached Site Plan
and backup documentation identify the location and configuration of the new septic
system and alternate site and the parameters used in the design. Also identified on the
plans are the location of the proposed well, test holes and the wells and septic systems
on the surrounding lots. Drainage arrows and spot elevations are shown indicating the
current drainage patterns. The drainage patterns will be maintained after construction.
The test holes placed near the location of the proposed absorption trench and alternate
site indicated clean sand with some gravel and varying amounts of silt and percolation
rates approximating 2 to 5 minutes per inch. No ground water was found during
placement of the test holes and none was noted during the monitoring period. We are
therefore proposing to place a 1,250 -gallon septic tank and a 35' long x 3' wide x 8'
effective depth absorption trench. The distribution pipe will be placed 2' below the
existing surface and the total depth will be 10'. Sufficient fill will be placed over the
septic tank and absorption trench to prevent freezing.
The ground surface on the lot slopes as shown on the site plan from west to east at
varying slopes. The absorption trench will be constructed at the front of the lot parallel
with the slope as much as possible in conformance with Municipal requirements. All
components of the new septic system will be constructed a minimum of 100' from any
surface water and 100' from the well on this and adjacent lots.
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 subdivision is currently
South % Lot 18, Section 10. T12N, R4W
May 27, 2003

served by the Municipal water system.
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,
Eat" �

ON-SITE WASTEWATER DISPOSAL SYSTEM
CONSTRUCTION AND MATERIAL SPECIFICATIONS
SUBJECT: SOUTH % LOT 18, SECTION 10, T12N, R4W
GENERAL:
1. The scope of this project includes the procurement and placement of a
new 1,250 -gallon tank at the location shown on the site plan. Work
also includes the construction of a new absorption trench 35' long by 3'
wide by 8' effective depth also at the location shown on the Site Plan.
The total depth of the trench will be 10' below existing ground and the
distribution pipe will be placed at 2' below the surface. All components
of the new absorption trench and septic tank must be constructed a
minimum of 100' from any surface water and 100' from wells on this
and adjacent lots. A minimum of 4' of cover is required over the septic
tank and 3' over the absorption trench. In lieu of cover 2" of direct
bury insulation and 2' of cover may be placed.
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.
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 a certified
septic tank manufacturer if the existing tank is found to be defective.
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.
South 1/2 Lot 18, Section 10, T12N, R4W
May 27, 2003
Page 2 of 3
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 drainfieid 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.
MATERIAL SPECIFICATIONS:
1. Septic tanks must be constructed by a municipally approved septic
tank manufacturer.
2. 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

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.
