Re: 544 Johnson Street(Map 38,Lot 48)
Dear Mr. Morin:
The proposed wastewater system design plan for the above site dated November 11, 2020 has
been reviewed. Unfortunately,the plan cannot be approved 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.
1. Provide a statement identifying property is within or not within Watershed of Lake
Cochichewick(NA 3.2)
2. Notate top of septic tank shall be<=36"below grade(310 CMR 15.221(7))
3. The ESHWT and chamber bottom in the system profile are shown at 91.83 and 94.32,
respectively. This separation is 2.49' instead of the requested 3' separation.
4. The system profile shows the ESHWT at 91.83 and notes the offset from ESHWT is 4.0'.
As stated above,the requested separation is 3'.
5. The buoyancy calculations show a water column of 2.69' while the calculation of
displaced water weight uses a water height of 1.06'. Raise the elevation of the tank or
explain this calculation.
6. In the cross section of the cultec chambers, note the type of fill material to be placed
beneath, over and around the chambers and above the filter fabric.
7. The system profile calls for a distribution box with 6 outlets, 3 of which are plugged
(leaving 3 distribution lines). The plot plan shows that there are 4 distribution lines.
8. The benchmark on the plot plan is the top of wall at 100.00 while the benchmark in the
general notes section is the bulkhead at 100.05. Make any necessary edits to provide
consistency for the contractor and/or installer.
9. Clearly depict how the distribution lines are connected to each of the cultec chambers and
if there will be one or two pipes feeding each section.

10. Since the system is proposed as an alternative soil absorption system the"Standard
Conditions for Alternative Soil Absorption Systems with General Use Certification
and/or Approved for Remedial Use"will apply. Please provide the following as required
by the approval conditions
a) a certification, signed by the Owner of record for the property to be served by the
Technology, stating that the property Owner:
i. has been provided a copy of the Title 5 I/A technology
Approval, the Owner's Manual, and the Operation and
Maintenance Manual, and the Owner agrees to comply with
all terms and conditions;
ii. if the design does not provide for the use of garbage grinders,
the restriction is understood and accepted; and
iii. whether or not covered by a warranty, the System Owner
understands the requirement to repair, replace, modify or take
any other action as required by the Department or the LAA, if
the Department or the LAA determines the System to be failing
to protect public health and safety and the environment, as
defined in 310 CMR 15.303.
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.
Sincerely,
