Star Route A, Box 1651
Anchorage, AlasKa 99502
Dear Mr. Lubrecht:
Per your request we have inspected the sewage disposal system located on
Lots 1 and 2A of Alyeska Subdivision. Our investigation has revealed the
following inadequacies with the system in its present condition[
1. The septic tank presently contains approximately 5 feet of solid
waste. This appreciably decreases the total effective volume of
the tank. With this decreased useable volume in the tank the
settlement time is greatly reduced. Therefore, most of the solids
that should be removed in the tank are being passed on to the '.
leaching field. This has tended to plug the filter media in the
field, and therefore reduce its ability to accept effluent.
e
The first distribution box only contains 3 active distribution
lines and 3 inactive lines of 20 ft. length, instead of 6 lines
.of 40 ft. length per the design. The third distribution box
does not appear to be in existence. This would indicate that the
field has a deficiency of 7 distribution lines.
The distribution boxes have no gravel cover. We also' noted that
one distribution line has only 15" cover at the end. This would
indicate that the field only has 1 ft. to 2 ft. of cover over the
distribution lines vs. the 3.5 to 4.5 feet shown ot the design
drawings. We also noted that the distribution b6xes'do not~ have
metal lids, but are covered, with plywood.
Our preliminary investigation also included rough measurements
in the field which indicate that the field is shifted north
about 25 to 30 feet from its design location.
Based on the assumption that the third distribution box is.not in existence
and we only have the equivalent of nine 40 ft. lengths of perforated pipe
then we would recommend that the following activities take place in order to
bring this field up to its design capabilities.
1. The septic tank must be pOmped out completely,.to include ALL
sludge deposits.
2. The septic tank will need to be heated so that the inside temp-
page 2
erature is ma ~ained at a minimum of 45°F th A§hout the year,
Enzymes will have to be added on a monthly basis or as required,
The two existing distribution boxes will need to be pumped out
so that the field will backflush, We would recommend that back-
flushing take place for a period of at least 6 hours, W~ also
recommend that metal lids be placed on the distribution boxes.
4. Seven new distribution lines must be added~to the field. These
Would be in a third distribution box.
A 6 ft. wide sheet of 6 mil polyethylene film must be centered
on all distribution lines on top of the existing fill. Then
place 2 ft. of coarse gravel (3~-) over the entir~ f~e]~d tb~
extend 25 ft. beyond the edges of the field to the north, west;
and south- Place 6 mil polyethylene 6~6r the gravel along the
north and south sides extending 30 ft. in from the edge. At the
edge of the gravel, the polyethylene shall extend into the existing
ground a minimum of 18", Once the polyethylene is in place cover
the entire field With an additional 1 ft. of gravel.
6. The chlorination system recommended in oun letter of. July 23,.1975
'be installed.
We also recommend the following maintenance procedures to keep the system
in proper working condition.
l, The septic tank be pumped of sludge at any time the sludge is over
.2 ft. deep.
2. The field be backflushed for a minimum of 6 hours each 6 months.
3. Enzymes be added on a monthly basis or when it.is apparent that the
biolobical activity is decreasing.
We feel that by taking the above action you should be able to bring the
system up to a condition to handle the existing units as well as the two
proposed units until the scheduled municipal sewer system is completed.
Due to the high water table the field is marginal. We feel it is therefore
critical to the success of this field that the septic tank function as efficiently
as' possible, and that the chlorination system also function at peak efficiency.
We would like to point out that this report is a general review of what we
feel would be a likely solution to the sewage problem. In order to ini~t~te'~'
%he~c6rrectiv6~meas~re~'no~ed'~bo~itiwil.l,~be~ne~essar~ ~o~dete~i.~e~
exactly what is actually existing in the distribution system and its condition,
design the changes, and stake the improvements.
If we can be of further assistance, please call on us.
S~ncerely,
BELL, HERRING AND ASSOCIATES
