SPECIFICATIONS & DESIGN GUIDELINES
Wastewater System Sizing: The current holding tank is failing. Replace holding tank
near same location, but outside the well radius. Decommission old tank per UPC. This lot
is about a 3`d of an acre and on a private water well. Separation measurements to be made
prior to construction. No adverse impacts are expected from tank replacement. No
easements are present on the lot. The slope in the area of the septic system is negligible.
No conflicts to neighbor properties. Install matching Alarm system w/ Holding Tank.
Specification Requirements: All components and work must comply with the
Municipality of Anchorage Specifications (AMC) & State of Alaska Drinking Water
Regulations and Wastewater Regulations.
• New 2000 gallon MOA-approved holding tank. Watertight couplings on inlet &
outlet.

The Required Size of the Soil Absorption System Is:
DEPTH LENGTH GRAVEL DEPTH WIDTH
The length dimension is the length(in feet) of the trench or drainfield. The
depth of a trench or pit is the distance between the surface of the ground and
the bottom of the excavation(in feet). There is no set width for trenches.
The gravel depth is the minimum depth of gravel between the outfall pipe and
the bottom of the excavation(in feet).
* * REQUIRED SEPTIC(HOLDING) TANK SIZE = GALLONS * *
Permit applicant has the responsibility to inform this department during the
installation inspections of any wells adjacent to this property and the number
of residences that the well will serve.
* * * TWO(2) INSPECTIONS ARE REQUIRED * * *
Backfilling of any system without final inspection and approval by this departmen~
will be subject to prosecution.
Minimum distance between a well and any on-site sewage disposal system is 100 fee-
for a private well or 150 to 200 feet from a public well depending upon the type
of public well. Minimum ~is~ance from a private well to a private sewer line
is 25 feet and to a community sewer line is 75 feet. Well logs are required
and must be returned to this department within 30 days of the well completion.
Other requirements may apply. Specifications and construction diagrams are
available to insure proper installation.
* * * PERMIT EXPIRES DECEMBER 1 9 8 3 * * *
I certify that:
(1) I am familiar with the requirements for on-site sewers and wells as
set forth by the Municipality of Anchorage.
(2) I will install the system in accordance with codes.
(3) I understand that the on-site sewer system may require enlargement if
the residence is remodeled to include more~o~s/q

September 13, 1955 (Plat #387)
R6 in 1982. Previously, it was zoned UNRESTRICTED
61 lots and 3 tracts. Majority of the lots are 20,000 s.f.
One of the affected lots is only 14,365 S.fo
Water table has increased in recent years causing systems to
fail and sewage to leak onto the ground surface. Lots most
affected are cross-hatched on Figure 1. Based on soil tests
conducted in 1982 on several of these lots,' water levels have
increased 4-6 feet.
System failure in this case can contaminate the shallow water
table, and the potential exists for contaminating the deeper
drinking water aquifers although no problems have surfaced to
date.
Due
1.
°
o
to a combination of 3 factors;
Natural phenomena - A natural increase in the water table
due to changes in the hydrologic cycle. There is historic
evidence that the area affected was very wet, saturated by
ground water, prior to development. There are presently
many indications of saturated soil as evidenced by small
streams, springs, and weeps within the affected area.
Monitoring well data helped establish the boundaries of
the affected area.
A stream diversion around lots 8,9, and 10 may be a factor
in fixing the water table elevation on Lot 15, Block 3,
although the degree of impact is difficult to assess and
is not the sole factor.
Wastewater loading from septic systems probably aggravates
the situation by contributing to the water table rise.
Lots 12-15, Block 3 and Lots 5-6, Block 4 will be required to
abandon their existing systems and hook up to a holding tank
or package treatment plant (innovative) by November 1, 1985.
Lots 3-4, Block 4 will be required to raise the absorption
field to meet the proper separation distance to ground water.
Curtain drain systems are not viable and have been excluded as
an option.
High fecal coliform levels found in a monitoring well on Lot
3, Block 5 are currently being investigated. The water supply
well for this lot is in close proximity and is only drilled to
a depth of 44 feet with a static water level of 6 feet from
the ground surface.
