Dear HHS staff,
I witnessed the flow test on this well. It was done with a five-gallon bucket and was the
most imprecise test imaginable. A heavy, drizzle-like mist was blowing up to 20 feet
from the drilling orifice. This mist accounted for up to several gallons per minute not
captured in the flow test. Several more gallons per minute were being ejected straight up
before flowing down around the casing. This water was also not accounted for in the
flow test. In summary, there was water running everywhere with perhaps half of it going
in the bucket.
I am not faulting the driller. He did a very good job drilling this well and I'm told that
holding a five-gallon bucket under the drilling orifice is the normal method to test the
production of domestic water wells in this area. However, as a professional scientist
accustomed to carrying variance to the fourth decimal I find this method somewhat
imprecise and hope that you don't place too much credence in flow-rate results generated
by this methodology. If these reported flow rates are important to the consumer, I
suggest you develop and require a standard method that is more precise.
Sincerely,
La~ Bartlett

A test hole was excavated and a percolation test performed. The approximate location of
the test hole is located on the attached site plan.
The monitoring tubes within the test holes have been checked and found to be dry.
Ttfis property has enough area for a future septic upgrade which can be seen on the
attached site plan.
We do not anticipate any adverse effects on neighboring wells, septic systems or drainage
patterns by the installation of the proposed septic system.

REFERENCE: Lot 11, Block 3, Greatland Estaes Subdivision
September 25, 1997
GENERAL:
The scope of this project includes the installation of a 1250 gallon septic tank and a
five foot wide draintield to serve the proposed three bedroom residence for the
referenced property. ( q ~ ~ ,~a, ~ o,., ~ ~ ~, ~, ~, )
Construction shall be in accordance with the approved site plan and design
drawings, Municipal permit with any special provisions or conditions, and all
applicable State and Municipal Wastewater Disposal Regulations.
The contractor shall be responsible for obtaining any necessary underground utility
locates.
Unless specifically agreed otherwise, the property owner shall be responsible for
final grading areas subsequently depressed from soil settling. On all teachfield
mound systems, the property owner shall be responsible for ensuring a satisfactory
vegetation growth over the mounded area.
o
Contractors installing wastewater disposal systems must be certified by the
Municipal Health Department fbr system installations. Owners installing thek own
systems must also receive prior approval from the Municipal Health Department.
~EPTIC TANK INSTALLATION:
A septic tank is to be constructed by a certified septic tank manufacturer.
Construction shall include two 4" cleanouts for pumping access.
The septic tank shall be sufficiently bedded to prevent settling or shifting of the
tank.
All standpipes on 'the septic tank shall extend a minimum of 12 inches above final
grade.

Page Two
Lot 11, Block 3, Greatland Estaes Subdivision
September 25, 1997
Septic tanks installed with less than 4 ft. of cover shall be insulated.
A foundation cleanout shall be installed one to four feet from the building foundation. In
the line between the tank and the leachfield there shall be two adjacent cleanouts (unless an
effluent pumping system exists within the septic tank). These cleanouts shall be located on
undisturbed soil not more than 10 ft. from the tank. The first cleanout, in line, shall be to
clean toward the leachfield. The second cleanout shall be to clean toward the septic tank.
Final grading over the septic tank shall be such that a positive slope exists away from the
septic tank.
ABSORPTION TRENCH/DRAINFIELD INSTALLATION:
Excavate the proposed trench to the dimensions shown on the design. The bottom of the
excavation shall be within 2 inches of level. If the sidewalls of the excavation become
smeared, they must be raked or scratched (ruffed-up) before gravel (sewer rock)
placement.
Once the gravel is installed, the distribution pipe is to be installed level with the perforations
faced downward. Gravel is then to be placed over the distribution pipe to provide a
minimum of 2 inches of cover over the pipe.
A silt barrier must be installed between the final gravel layer and the native soil backfill.
Ensure the silt barrier covers the entire gravel surface before placing backfill.
Monitor tubes shall be of four (4) inch diameter, installed approximately in the locations
shown on the design, and extend a nfinimum of 12 inches above final grade. The portion of
the monitoring tube extending through the gravel shall be perforated from the bottom of
the trench to the invert of the distribution pipe. This is equivalent to the effective depth of
the gravel as noted on the design.
Bacld~l! over the final gravel layer must not be less than twenty-four (24) inches. Insulation
must be installed when the back{ill depth is less than thirty-six (36) inches. The finish grade
over the trench must be mounded to prevent the formation ora depression after settling.
MINIMUM ._MATERIAL SPECIFICATIONS:
1. Any septic tank proposed for installation must be constructed by a Municipally approved
septic tank manufacturer.

Lot 11, Block 3, Greatland Estaes Subdivision
September 25, 1997
The following pipe materials are approved for use in septic system installations in the
Municipality of Anchorage:
Type of Pipe Perforated Solid
o
Cast Iron Yes Yes
ASTM D3034 (PVC) Yes Yes
ASTM F810 (HDPE) Yes No
ASTM D2662 (ABS) Yes Yes
Use of a type of pipe other than listed above must be approved by the inspecting engineer.
Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical
Company Styrofoam HI or equal).
Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Femco, or
equal).
A permeable nontoxic silt barrier (Typar 3401, lV~rafi 140N, or equal) must be installed
between the final leachfield gravel layer and the native soil backfill.
All leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3%
passing the ~f200 sieve.
When sand is being used as a filter material, its gradation specifications must conform to
current M.O.A. or D.E.C. requirements, which ever applies.
INSPECTIONS:
Typically there will be a minimum of three (3) inspections requked during the installation of the
wastewater disposal system. These inspections will occur as follows:
The first inspection must be conducted after the excavation of ditches, pits,
trenches, or beds and before the installation of any gravel. A septic tank may be set
in place, but may not be backfllled before this inspection.
The second inspection must be conducted after the placement of the silt ban/er,
gravel, distribution lines, standpipes, cleanouts, and insulation, but before the
placement of any other backfill.
3. The final inspection is to occur upon final grading of the property.
Page Four
Lot 1 l, Block 3, Greatland Estaes Subdivision
September 25, 1997
Often there will be more than these 3 inspections required. Especially with the installation of
multiple trenches, sand filters, pressurized distribution systems, etc. Thus, the inspecting engineer
is to be contacted at lea3t 24 hours prior to the start of construction. If necessm'y, a pre-
construction rn~ting will take place on-site. The h~specting en~neer will not coordinate, direct or
contro! in any way the contractors a¢.ivities.
The owner shall contract with the contractor to perfom~ the work outlined in these specifications
and plans ~md in a~ordance with the attached M.O.A. permit. Them will be no contractu~
an'angement existing between the contractor and
S & S Engineering. S & S Engh~ee~ug shall be the owner's representative and will inspect the
work ~ stated above to document the contractors activities. Final acceptance of the contractors
work rests with the owner and the M.O.A.
S & S En[,fineefing shall ha~-e no liability 'to the oxvner or to others for acts or omissions of the
contractor or any other p(~so~s performing work on this project or the failure of the contractor to
ca..fy out the work in accordance with these consntmction docmments. S & S Engineedng's
