Ref: Septic Upgrade Design for Lot 1, Block 4, Greenland Subdivision
To whom it may concern:
The proposed 4 bedroom house is served by a private well and septic system. The existing septic
system consists of a 1250 gallon septic tank and a trench. The trench was found to be surcharged
and needs to be upgraded. One test hole was excavated on the property. We are proposing install
a new 1250 gallon septic tank and a new drainfield. Comment regarding the proposed design are
summarized as follows:
1. SOILS: Attached are logs which shows the soil profile, and the percolation test results. In the
test hole, the soils below the organics was a GW material to a depth of 3.5 feet and then
transitioned to a tight ML material to a depth of 5.5 feet. From 5.5 feet to 16 feet the soil was a
SM material. No groundwater was encountered during the excavation of the test hole.
Groundwater monitoring was peformed 7 days later (8/12/99) and found the monitoring tube to
be dry. A percolation test was performed between the depth of 6.0 feet to 6.5 feet and the rate
was determined to be 8.6 minute/inch.
2. TRENCH DESIGN:
a. Percolation Rate: 8.6 minutes/inch
b. Allowable Application Rate: 0.8 gallons/day/ft2
c. Number of Bedrooms: 4
d. Design Flow: 600 gallons per day
e. Minimum Absorption Area: 750 ft2
f. Total Depth: 9.5 feet
g. Effective Depth: 4 feet
h. Width: 5 feet
i. Reduction Factor: 0.50
i. Minimum Length: 80 feet (inner measurements)
j Effective absorption area = 800 ft2
3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed
upgrade.
4. TOPOGRAPHY: The average topography of this property is generally flat, and there are no
slope concerns. The trench is to be installed parallel to slope contours.
5. LOT LINE WAIVER: The proposed septic system will be on, or immediately adjacent to,
the west lot line. Both lots are owned by the same person/s and it is their intent to utilize the two
lots indefinitely as one parcel.
I am unaware of any adverse impacts this installation would have on adjacent wells or septic
systems. If you have any questions, please contact me at 337-6179, or 244-9612. Thank you
for your assistance,t

* The bottom of all trench/ted excavation
* Top of sand on all sand filters
* Top of drainpipe
* Septic tank, or lift station, or holding tank prior to backfill
* Placement of filter fabric and insulation
* After final grading is completed
Additional inspections may be required depending on the construction methods used by the contractor and
the type of system being installed.
2. The inspecting engineer has no dkect authority over the contractors activities or construction practices.

5. The sewer service line from the house to the tank shall be sloped a minimum of 1/4"
per foot, unless prior approval is obtained from the engineer.
6. The inlet and outlet lines from the tank shall be bedded in drainrock or the soil shall be adequately
compacted to prevent future settlement of the soil.
7. A foundation clean-out will be installed, 1-4 feet from the house, if one does not currently exist.
8. Post tank clean-outs shall be installed per MOA requirements. Does not apply to holding tanks or lift
stations with pressurized lines.
9. All tanks shall be anchored to resist buoyancy fomes in high groundwater areas. This applies when
there is not adequate soil cover to resist buoyancy forces. Engineer shall make this determination.
10. The f'mal soil cover shall be graded so that there is positive drainage away from tank.
11. All holding tanks and lift stations shall have an audible and visible alarm inside the residence.
12. All lift stations shall be wired in compliance with all MOA guidelines and the Uniform Electrical

· Installation of Conventional Absorption Bed & Trenches:
1. Excavate the proposed bed/trench to the dimensions shown on the design. The bottom of the excavation
shall be within 2 inches of level (2 inch maximum variation between high and low spots). If the sidewalls
or bottom of the excavation become smeared, they must be raked or scarified before placement of the filter
sand or drainrock.
2. The trench or bed should be at least 5 feet from the test hole excavation.
3. Ali soil tests and excavation depths are advisory to the design and are to be verified in the field by the
engineer. If design changes are necessary, and the changes effect the contractor charges to the property
owner, the contractor shall obtain approval from the property owner prior to proceeding with the work.
4. Once the drainrock is installed, the distribution pipe is to be placed level (0.02 feet difference between
high and low shots) with the perforations faced downward. Drainrock is then to be placed over the
distribution pipe, to provide a minimum of 2 inches of cover over the pipe. The drainrock shall not be
pyramided over the drainpipe but shall be the same elevation over the entire trench/bed width.
5. A silt barrier must be installed between the fmal drainrock layer and the native soil backfill. The silt
barrier shall cover the entire drainrock surface.
6. Monitor tubes shall be installed at the locations shown on the design drawings, and extend a minimum
of 12 inches above fmai grade. The portion of the monitoring tube extending through the drainrock shall
be perforated from the bottom of the trench/bed to the invert of the distribution pipe.
7. Backfill over the fmal drahirock layer must not be less than 2 feet. Insulation must be installed when
the backfill depth is less than 3 feet. The insulation shall cover the entire width of the trench/bed, the
contractor shall "shoot" the fmal grades to ensure cover depth is adequate, prior to notifying the engineer
that the work is complete. The final cover over the drainfield must graded so that there is no potential for
water to pond over the trench/drainfield.
