DATE: October 6, 1998 —
SUBJECT: W. Michalowski Property, Coles Meadow Rd. - Septic Permit
The Northampton Board of Health has reviewed the Disposal Works Construction Permit
application and a revised septic system plan for the Michalowski Property, Assessors Map 8,
Lot 04, Coles Meadow Rd. The Board of Health has issued the permit for the construction of
a septic system on the property.
Enclosed please find an approved copy of the system plan and two copies of the Disposal
System Construction permit. One copy of the permit and the approved plan must be
submitted to the Building inspector in order to obtain a building permit. The other copy of
the permit must go to Mr. Michalowski.
Before construction of any dwelling on that property can begin, a drinking water
supply well must be installed and tested for potability by a State Certified Testing
laboratory. A copy of the test results must be submitted to the Board of Health.
In addition, the name of the Licensed Septic System Installer,who will be constructing the
septic system, must also be submitted to the Board of Health.
Once the septic system construction begins the contractor must notify the Board of Health a
minimum of 24 hours prior to the completion of construction so that an inspection of the new
septic system can be scheduled. The septic system design engineer must also be schedule for
an inspection before the system is buried.
Please contact the Board of Health office with any questions. Thank you.

Notes:
1. The minimum wall thickness for reinforced concrete shall be two inches.
2. The invert elevations of all outlets shall be equal to each other and located
at least two inches below the invert elevation of the inlet.
3. Cover of distribution box to be watertight.
4. There shall be a minimum sump of six inches as measured below the outlet
invert elevation.
5. The minimum inside dimension of the distribution box, regardless of material,
shall be 12 inches.
6. When the soil absorption system is to be dosed or when the slope of the inlet
pipe exceeds 0.08 feet per foot, an inlet tee, baffle or splash plate extending to
one inch above the outlet invert elevation shall be provided to dissipate the
velocity of the influent.
7. Distribution box shall be installed on a level stable base that will not settle.
8. Distribution box to be placed on a 6 inch layer of compacted 3/4"-1 1/2" stone.
9. Distribution box outlets to be laid level for a distance of 2 feet, then sloped
to leaching system.
10. Distribution box shall be capable of withstanding H-20 loading. yes /no
11. To insure proper distribution, all lines must discharge equally. Testing will
be done with water, prior to final inspection and/or at the final inspection in
presence of the engineer.

1. Distance between excavation sidewaIls shall be no less than three times the effective width or depth,whichever
is greater. In no case shall the distance between excavation sidewalls be less than 6 ft. if the area between the
trenches is to be used for reserve area.
2. All distribution pipe from the D-box to the leaching trench shall be unperforated and shall be laid with tight joints..
3. Trench pipe shall have a minimum slope of 0.005 ft./ft.
4. All stone must have less than 0.2% material finer than a number 200 sieve as determined by AASHTO T-11
and T-27(latest edition).
5. Pipe shall be capped 12 inches from the end of the trench.
6. Pipe shall be constructed of either polyvinyl chloride(PVC),acrylonitrile-butadiene-styrene (ABS),or
high density polyethylene(HDPE). PVC pipe shall be schedule 40 General Purpose Sewer Pipe(ASTM D 1785),
schedule 40 Drain,Waste and Vent Pipe (ASTM D 2665) or SDR 35 PVC Gravity Sewer Pipe and Drain Pipe
(ASTM D 3034). ABS pipe shall be schedule 40 (ASTM F 628). HDPE pipe shall meet or exceed ASTM F 810
for Smoothwall Polyethylene Pipe for use in Drainage and Waste Disposal Fields.
7. All system components shall be installed in accordance with TITLE V of the state sanitary code and any applicable
local rules and regulations.
8. The bottom of all trenches shall be installed level at the design elevation given for each trench.
9. Trench sidewalls shall be scarified to remove any smearing of soil done during excavation.
10. Any change to this plan must be approved by the Board of Health and the design engineer.
11. The system shall not be backfilled prior to inspection and approval by the Board of Health and/or the engineer.
12. No permanent structure shall be constructed over the 100% expansion area.
13. Heavy equipment shall not be permitted to pass over the leaching area.
14. Any conditions encountered during construction differing from those shown on the plans shall be reported
to the design engineer before construction continues.
15. Distribution lines exceeding 50 feet in length shall be connected and venting provided in accordance with
310 CMR 15.241
16. Contractor will give engineer and Board of Health representative a minimum of 3 days notice for any
inspections.
