Dear Sirs:
The purpose of this letter is to provide the required design narrative in support of our application for
a permit to construct wastewater disposal facilities on Lot 2, Peregrine Heights S/D, located on Upper
Huffman Road. Soils logs, perc test results, a site plan, design drawings and specifications are enclosed
for your review.
The proposed system will be constructed in the vicinity of test hole # 1. As can be seen from the soil
log, the native material between 7 and 11.5 feet below ground level is a silty gravelly sand with a
measured perc rate of 3 - 9 minutes per inch. Using the soil application rate of 0.8 gpd/sq. ~. specified in
the wastewater ordinance, this proposed 3 bedroom residence requires a total absorption area of (3 x
150)/0.8 = 563 square feet. The proposed design consisting of 2 parallel 57 foot long x 5 foot wide soil
absorption drainfields has a total absorption area of 570 square feet.
The topography of the lot slopes down towards the northwest at approximately 14%. Bedrock was
encountered at 12 feet in test hole #1 and at 13 feet in test hole #2 ·
The proposed project will have no significant impact on present or future water Supply and
wastewater disposal systems serving adjacent properties, nor will it have any significant impact on
reserved space-surface and subsurface, or on drainage.
Please give me a call at 345-1355 if you have any questions on this submittal.
Sincerely,
Ted Moore, P.E.

Wastewater disposal system installation
Specifications
1.0 General:
1.1 The scope of the project consists of installation ora 1000 gallon septic tank which discharges
into two parallel 57 foot long x 5 foot wide soil absorption drainfields.
1.2 Construction shall be as depicted on the approved site plan and design drawings. Minor
deviations from these drawings may be allowed or required by the engineer conducting the inspections.
All construction procedures and material specifications shall conform with Municipal and State
requirements. All separation distances shall be in conformance with Municipal requirements, unless
specifically waived.
1.3 The contractor shall be responsible to obtain any necessary utility locates, and to work around
any buried utilities.
1.4 The contractor shall provide adequate cover material and rough grading over all system
components to ensure that proper drainage is achieved after settlement and that there are no residual
depressions. Insofar as possible the contractor shall minimize damage to trees and existing lawn areas.
1.5 Unless specifically agreed otherwise, the homeowner shall be responsible for finish grading after
the soil is compacted, as well as placement of topsoil and reseeding all areas disturbed by the
construction.
2.0 Septic Tank: ,,
·
2.1 The new 1000 gallon, 2 compartment septic tank shall be Municipally approved and shall be set
level on undisturbed soil. Each compartment shall be equipped with a watertight manhole cover and a 4"
cleanout. If the tank is buried less than 4 feet, it shall be insulated with 2 inches of approved burial type,
rigid insulation.
2.2 All pipe connections to the tank shall be equipped with waterproof mechanical couplings. The
waste line from the residence to the septic tank shall have a minimum slope of 1/4'" per foot, and the
waste line between the tank and the soil absorption system shall have a minimum slope of 1/8" per foot.
A cleanout shall be installed within 5 feet of the building foundation, and a double cleanout shall be
installed within 5 feet downstream of the septic tank.
3.0 Soil absorption system:
3.1 The soil absorption system shall be constructed in the vicinity of test hole #1 by excavating two
parallel 57 foot long x 5 foot wide trenches to a maximum depth of 8 feet below original ground level.
The axes of the drainfields shall run parallel to the natural contours of the land, and there shall be a
mininmm of 10 feet of undisturbed soil between the drainfields.
3.2 The bottom of the excavations within each drainfield shall be level, but due to the sloping
topography, the two drainfields will be at different elevations. Any compacted or smeared surfaces shall
be raked to allow proper infiltration. Sand for leveling or serving as filter material shall comply with
Municipal specifications.
3.3 Two feet of filter sand shall be placed in the bottom of each draitffield excavation, bringing the
elevation of the bottom of the drainfield up to no greater than 6 feet below ground surface. A total of 1.0
feet of approved sewer gravel shall be placed on top of the filter sand with the perforated distribution
pipes laid level such that the pipe inverts are no less than 0.5 feet above the bottom of the sewer gravel.
Sewer gravel shall be 0.5" - 2.5" screened gravel, with less than 3% passing the #200 sieve.
3.4 Monitor tubes and cleanout pipes shall be of 4" diameter and installed in the locations shown on
the design drawings. The portion of the monitor tube extending through the sewer gravel shall be
perforated.
3.5 Approved filter fabric shall be placed over the entire top surface of the sewer gravel. A minimum
of 2 feet of soil cover is to be placed over the filter fabric. If the soil cover thickness is less than 3 feet,
two inches of rigid, burial type insulation is to be placed over the entire top surface of the gravel, in
addition to the filter fabric.
3.6 The top surface of the cover material shall be raised a minimum of 6 inches higher than the
surrounding terrain to allow for subsequent settlement, and shall be graded to smooth contours. Fill
slopes shall be no steeper than 3:1.
3.7 Unless specifically agreed otherwise the homeowner shall be responsible for arranging to have
the site finish graded after the backfill material has stabilized, and for placement of adequate topsoil and
seed to promote rapid revegetation of all areas disturbed by the construction.
4.0 Inspections:
4.1 A minimum of 5 engineering inspections will be required during the course of the project: (1)
initial stakeout with the contractor to establish the location of the system and to discuss the plans,
specifications and construction procedures, (2) after the native material has been excavated to expose the
infiltrative surface to ensure that it is level and at the right elevation, and conforms with the soil test
information, (3) after the sand filter material has been placed, (4) after the sewer gravel is in place and the
distribution pipes have been laid and connected up to the septic tank, but prior to placement of insulation
or filter fabric, and (5) after rough backfill and grading is complete. The septic tank requires one
inspection after it is set level and the piping connected, but prior to backfill. This inspection may be
incorporated with any of the above inspections.
4.2 The installer shall coordinate the timing of the inspections with the engineer sufficiently far in
advance to ensure the availability of the engineer.
