Thomas,
The proposed wastewater system design plan submitted for the above site 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 map and lot of parcel 15.220
2. Provide address of owner NA 3.2
3. Provide a locus 15.220
4. Indicate magnetic marking tape to be installed over system components 15.221
5. Notate distance from cellar wall to SAS to be 20' minimum 15.211
6. Provide the required 50' between the drain pipe which intercepts the water table and the
soil absorption system 15.211
7. Provide clarity for the installer that the building sewer is to have watertight joints, to be laid
on a compacted and firm base and in a continuous grade on a straight line 15.222
8. Septic tank to have 3" air space above baffles and 9" air space above flow line. Clarify
this for the installer 15.227
9. Gas baffle shown at outlet tee in tank detail is not easy to see, clarify this label for the
installer 15.227
1o. Visually depict the required manhole to within 6" of finished grade over the septic tank
opening for clarity for the installer 15.221 & 228
11. Indicate the tank and distribution box are to be watertight 15.221
12. Indicate the distribution box is to have all outlets at the same elevation 15.232
13. Indicate the leach pipe orifice size is to be 3/8" to 5/8" 15.251
14. Provide a detail of the inspection port to be constructed to guide the installer
15. Provide trenches that are connected and vented 15.251
16. On Sheet D-1:
a. General Notes 1, 2, 3 & 6 make reference to Haverhill, while this project is in North
Andover. Clarify this incongruity
b. General Note 6 makes a statement on behalf of the state and local government which
you are not in a position to indicate. Adjust or remove this wording
c. General Construction Sequence speaks to drilling a well on this property. No well is
shown on the site plan. Clarify this
d. Landscaped Area Cross Section provides for construction methodology which might not
be in compliance with Title 5. Clarify if this is to be the backfill methodology over the
soil absorption system or not, and if so, assure it is in compliance with Title 5

e. Cross section references section lines A-A and B-B. The location of these sections is
not provided on the site plan
f. Notation indicates the use of a 2-compartment tank, however the tank detail provided
does not clearly show a 2-compartment tank, nor does it provide information on
required piping to interconnect the two compartments. Clarify this discrepancy
g. Clarify what is an Inspection Plug that is identified on the distribution box
h. Septic tank note 6 refers to methodology for sealing a joint which is typically not present
on a monolithic tank. Clarify this discrepancy
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.
