Re: 404 Summer Street (Map107A,Lot 22)
Dear Mr. Smith:
The proposed wastewater system design plan for the above site dated January 4, 2018. and
received on January 19, 2018 has been reviewed. Unfortunately, the plan cannot be scheduled
for a Board of Health public hearing until the following items are corrected. The specific section
in Title 5: 310 CMR 15.000, or North Andover regulation that is not met by this design follows
each item where applicable.
Sheet 1 - Site flan View
1. The test pits should be graphically depicted to accurately reflect the orientation they were
dug during the soil evaluation.
2. The existing system location was not shown (NA 3.2).
3. The outlet elevation of the foundation was not depicted(NA 3.2).
4. The finish grades should be clearly labeled and finish spot grades should be used as
needed specifically above the tanks, distribution box and leach field. It is not possible to
determine if the proper depth of cover material is being proposed above the system
components.
5. Provide a note to indicate the required finish grading above the leach field shall have a
minimum slope of 0.02 feet per foot(3 10 CMR I5.240(10).
E. A Swale is required between the northern side of leach field and the property line to direct
runoff away from the abutting property (3 10 CMR 15,255(2)),
)),

7. Note#8, provide more detail for the sand fill specifications in the leach field (3 10 CMR
15.255(l).
8. Indicate if the existing chain link fence is being proposed to be removed.
Sheet 2 -Details, Profiles and Notes
9. The survey statement is required to be signed and dated(NA 3,2).
10. The variance request should be clearly depicted on the design plan as a separate block or
note. Currently it appears to be part of system specification note#13.
11. Indicate the manufacturer and models numbers for the septic tank, effluent filter,pump
chamber, and distribution box.
12. Annual maintenance for the effluent filter is required and should be indicated on the
design plan (3 10 CMR 15.227(7).
13. Indicate if the proposed tanks are H-10 or H-20 loading (310 CMR 15.226(3)),
14. Buoyancy calculations are required for the septic tank and pump chamber(3 10 CMR
15.221(g).
15. The profile view not to scale should clearly show the manhole covers to finish grade
above the outlet of the septic tank and pump chamber. There is a notation but the covers
are graphically shown below grade.
16. The profile view not to scale should have an arrow to indicate the proposed location of
the 'A"weep hole in the pump chamber.
17, The scaled profile view has the same dashed line type for the original and final grade
lines.
18. The scaled profile view depicts the incorrect bed bottom elevation of 101.90 and top of
stone elevation of 103.45.
19. Provide a note to indicate a riser is required above the distribution box if there is more
than 9" of cover material (3 10 CMR 15.232(3)(f))•
20. Indicate the flow back volume of the force main pipe in the pump calculations (3 10 CMR'
15,231(2).
21. The pump parameters (9' at 60 gpm) appear to intersect at the end of the pump
performance curve. You may wish to consider re-sizing the pump based on the
parameters,
22. Pump note#9 indicates the incorrect gallons/inch for the pump chamber.
23. Indicate the size and material of the access covers above the septic tank and pump
chamber.
Please feel free to contact the office or Mill River Consulting at 978-282-0014 with any
questions you may have. We look forward to working with you to obtain a wastewater treatment
and dispersal system which will be in compliance with all regulations and assure protection of
public health and the environment of North Andover.
