Title 5 Septic System Plan for
235 Coles Meadow Road Northampton
General
a No work on this system construction shall take place until a permit for the approved system plan has
been received from the local Board of Health. A copy of the Disposal Works Construction Permit should be
on site for inspection during the time of construction. Additional specifications may be included elsewhere
in this design.
b. Loading requirements are specified for the septic tank on the system calculations page. Loading
requirements for any other component are on the drawing. Normal loading systems are designated H-10. If
H-20 rating is specified on the drawing and/or on the page for system calculations,the tank or leaching
facility shall be custom built to meet the increased loading requirements using additional rebar, greater wall
thickness and/or other approved methods. Follow the manufacturer's rating system and installation
procedures.
2. Septic Tank
Note: Not all plans require new septic tanks. Refer to the drawing to determine if a tank is required.
a The septic tank selected by the contractor shall conform with 310 CMR 15.223. The septic tank shall be
a minimum effective liquid capacity of 1,500 gallons below the outlet invert,rectangular,and with a
minimum length to width ration of 1.5:1. Liquid depth to be 48". Compartmentalized tanks are not to be
used.
b. Septic tank shall be installed on a minimum of 6"of crushed stone, leveled to grade and thoroughly
compacted Septic tanks shall have a minimum cover of 9". No structures shall be located directly upon or
above the septic tank access locations which interfere with performance, access, inspection, pumping, or
repair.
c. All three access covers to the septic tank shall have risers at least 20"diameter, if round,tightly fitted to
the tank to resist water infiltration, and terminated with a tight fitting cover no more than 6"below ground
surface. If, with the agreement of the Owner, one or more of the risers are terminated flush with ground,
these shall be secured against unauthorized entry with stainless steel hardware.
d. Inlet and outlet tees shall be of Schedule 40 PVC and shall extend a minimum of 6"above the flow line of
the septic tank and be on the center line of the septic tank located directly under the clean-out manhole. All
..fittings to be glued and secured against any movement due to horizontal or vertical impacts. Cross-sectional
•flow baffles shall not be used as substitutes for inlet or outlet tees. The inlet pipe elevation shall be no less
than 2"nor more than 3"above the invert elevation of the outlet pipe. Inlet tee minimum of 10"length below
water surface. The outlet shall be provided with a tee extending below the flow line 14"to 18". There shall
be an air space of at least 3"between the tops of the tees and the inside of the tank cover. Inlet tees may be
modified or a 6"riser on inlet cover may achieve this spacing. The tops of the tees shall be left open to
provide ventilation or separate ventilation shall be provided. The outlet tee and compartment connection
shall be equipped with a gas baffle. The effluent tee shall be fitted with a removable plastic outlet filter, as
manufactured by Polylok Inc., model PL-120,Zebco, or approved equal. Provide manufacturer's
maintenance data to homeowner and engineer.

e. Septic tank should be inspected by the Owner or his representative for solids accumulation annually.
When the sum of the sludge and scum layer approach 1/3 the net working volume of the tank(net of 16"
total thickness),as measured at the center of the tank, the tank is due for pumping. Septic tanks shall be
inspected and maintained in accordance with 310 CMR 15.300 and applicable local requirements.
3. Pump System Note: Not all plans require a pump and controls. Refer to the drawing to
determine if this system is required.
a. Pump chamber to be 1000 gallon concrete pump chamber unless otherwise specified elsewhere. Include
one manhole access 24"diameter that terminates at or above ground surface with a steel manhole cover that
can be secured.
b. Pump to be used is specified in the pump calculation worksheet.
c. Alarm system to be installed inside of dwelling unit in an accessible location. Alarm unit to have an
audible and visible indicator of water level above the pump on level. Include a shut off or silence mode. Use
CSI Controls model 5230 NEMA 4X Simplex or approved equal.
d. Pump circuit and control circuit to be on separate and dedicated circuit breakers installed by a licensed
electrician.
4. Distribution Box Note: Not all plans require distribution boxes. Refer to the drawing to determine if
a d-box is required.
a. The distribution box selected by the contractor shall conform with 310 CMR 15.232. Material of
construction shall be concrete or plastic lined concrete. A 6"sump is required in the d-box.
b. The distribution box shall be placed on thoroughly tamped and compacted sand or peastone a minimum
of 6"thickness, and shall be leveled utilizing a water flow test. Speed levelers shall not be used on a new
installation to obtain level and equal distribution flow,but should be installed after leveling is completed in
case uneven settling occurs in the future.
c. For inlet pipe slopes of 8%or greater,or where there is a pumped flow,the distribution box shall have
an internal cast baffle or solvent welded pipe tee to reduce the velocity of the influent flow. An internal pipe
"Y" is not acceptable.
d. For systems with different sections of the leaching facility at different elevations,the first 2 feet of pipe
out of the distribution box to be set dead level.
5. Piping
a . Piping to the septic tank(the building sewer) shall be 4"diameter, PVC Schedule 40 or better. Slope pipe
approximately 1/4" per foot length.
b. All piping from the septic tank to the end of the system shall be 4" diameter, SDR-35 or better, except
as noted on the drawings. Slope pipe approximately 1/8"per foot length.
c. Pressure piping, if any,to be 1.5"diameter, 160 psi black poly pipe or 2"diameter PVC Schedule 40
pipe, as called for in the page titled Pump Calculations.
6. Leaching Facilities
a. General: All leaching facilities to be of the size and location shown on the drawings. MI aggregate used

in leaching facilities to be of double washed stone. Where the name brand Infiltrator is called for in this
specification, other brands of the same dimensions may be substituted for the specified units.
b. Leach fields(Infiltrator Systems): Arrange Infiltrator chambers on levelled ground. Parallel rows should
be placed approximately 6"apart. Add end plates as per manufacturer's assembly directions. Fill spaces
between rows with Title 5 sand to the level of the top of the chambers.
c. Leach trenches (Infiltrator Systems): Assemble Infiltrator units as per manufacturer's requirements,as
shown on the drawing Material used to level bottom of trenches, if required,to be Title 5 sand or washed
stone.
d. Leach galleries: cement boxes with internal cast or cast-in-place distribution piping. Box dimensions 12
to 19"tall x 8' long x 5' wide. Place on 6"double washed stone. Set each gallery level. Pack tops of
horizontal seams between galleries with bitumen tape similar to the sealant tape used in septic tank seams.
e. Breakout barrier, if shown on plan,to be minimum 40 mil thick continuous sheet. Install barrier
vertically from bottom of excavation to height of top of leaching system. Seams of membrane material to be
overlapped a minimum of 12 inches and glued with sealant as recommended by manufacturer. Material to be
hypolon, low density polyethylene, buna-N rubber, EPDM, or approved equal. Backfill in lifts of no more
than 6"to assure minimal deformation of membrane. If material is wider than the vertical distance to be
covered as shown on the drawing, fold excess material over at the bottom of the trench.
Inspection
a. The contractor shall notify the System Designer a minimum of 48 hours in advance of the anticipated
completion time for a final inspection. The system shall be essentially complete at the time of the final
inspection,including all components in place,risers and covers installed,electrical components functional,
etc. No installed system component shall be buried greater than 1"depth at the time of final inspection. The
System designer shall verify the system was installed as designed and authorize the final grading.
b. If the System Designer finds the system is not ready for inspection after being called, or if serious
deficiencies are discovered,the System Designer must be notified to return to the job site when it is
complete. There will be a charge to the installer of$50 for each return trip,payable directly to the System
Designer at the time of the reinspection.
8. Final Grading
a At conclusion of work, loam and seed all disturbed areas to perennial grass mixture. Added loam may be
required for adequate grass growth. Mulch slopes with hay,burlap or netting to minimize erosion.
b.. Surface over leaching facility shall be pitched so as to shed rainwater.
c. Systems built late in the year, where the grass cover does not have a chance to establish itself,requires
the contractor is to return after spring thaw and resurface final grades and add grass seed cover as required to
equalize and stabilize all disturbed areas.
