Subject: Lot 986, T1 5N, R3W, Section 33 .
Septic System Design and Permit Application
Impacts to Adjacent Properties
Dear Onsite Services Engineer:
The existing septic system on Lot 986, T1 5N, R3W, Section 33 is near failure and must
be replaced. We are therefore requesting a permit be issued for the construction of a
new septic system to serve the four-bedroom home on the lot. The attached Site Plan
and backup documentation identify the location and configuration of the proposed
upgrade to the septic system. Also identified on the plans are the locations of the
existing well location and the well and septic system locations on the adjacent
properties. Drainage arrows are shown indicating the current patterns. The drainage
patterns will be maintained after construction.
Test holes placed on the lot indicate poorly graded silty gravel with some sand and
cobbles in the area of the new absorption bed. The percolation rate for this lense is 30
minutes per inch. Organic fill was placed on the lot in the distant past to a depth of
nearly 4'. This material was recently removed. Groundwater was found during
placement of the test holes at approximately 9' below the surface. The water then rose
to nearly 7' below the surface during the monitoring period. A subsurface drain was
placed along the eastern boundary of the lot to protect the area of the new absorption
bed from groundwater. Recent inspections of the monitor tubes indicate groundwater is
present in the area of the new absorption bed, but at depths of 6' below original ground
level. We are therefore proposing to place a new 1,500 -gallon STEP tank along with
a 40' long by 15' wide intermittent bottomless sand filter. The elevation of the
distribution line in the absorption bed will be 2' below the surface. The separation from
the highest measured groundwater will then be 6'. A minimum of 2' of coarse graded
sand will be placed to raise the bed above the groundwater elevation.
Lot 98B, T15N, R3W, Section 33
August 17, 2003
Page Two
The ground surface on the lot slopes at minor grades from the east to west. The new
absorption bed 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 the proposed well on the lot and the existing wells on the
adjacent lots. It will also be constructed a minimum of 100' from any surface water in
the area and 1 00'from the subdrain outlet.
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.
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,

ON-SITE WASTEWATER DISPOSAL SYSTEM
CONSTRUCTION AND MATERIAL SPECIFICATIONS
SUBJECT: LOT 98B, T12N, R3W, SECTION 33
GENERAL:
The scope of this project includes the pumping, removal and disposal
in accordance with ADEC requirements of the existing septic tank on
the property. It also includes the procurement and placement of a new
1,500 gallon combination septic tank and lift station and pressure
distribution system. Work also includes the construction of a new 40'
long x 15' wide Bottomless Intermittent Sand Filter at the location
shown on the attached Site Plan. A minimum of 2' of coarse sand
meeting the specification attached must be imported and placed in the
filter area. The 6" of pea gravel and distribution piping must then be
constructed atop the imported filter sand material in conformance with
specifications furnished by the supplier. The distribution piping for the
filter must be placed at the elevations shown on the Site Plan to
provide a minimum of 4' separation to groundwater. All work must be
completed in strict conformance with the manufacturer's requirements
for installation of the intermittent sand filter.
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 Contactor 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
by the Municipal Department of Health
system installations. Owners installing
receive prior approval from D.H.H.S.
installation.

2. The septic tank shall be sufficiently bedded to prevent settling or
shifting of the tank.
3. All standpipes on the septic tank shall extend a minimum of 12 inches
above final grade.
4. Tanks installed without 4' of cover shall have a minimum of 2" of direct
burial insulation.
5. A foundation cleanout shall be installed one to four feet from the
building foundation. Two cleanouts are required between the tank and
the drainfield.
6. Final grading over the tank/lift station shall be such that a positive
slope exists away from the septic tank.
ABSORPTION BED CONSTRUCTION:
1. The absorption bed shall be constructed to the dimensions shown on
the design. The bottom of the bed 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 trenches 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.
