Re: 1429 Osgood Street (Map 34,Lot 20)
Dear Mr. Keefner:
The proposed wastewater system design plan for the above site dated July 10, 2018 with a
revision date of October 17, 2018 and received on October 17, 2018 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. The location and log of all test pits and percolation tests were not depicted on the revised
design plan (310 CMR 15.220(4)(h-i)). All test pits and percolations tests that were
conducted on May 8, 2018 and.Tune 27,2018 should be depicted on the design plan with
the appropriate soil test data.
2. The existing grade elevation of the test pits used for the design of the septic system are
not depicted on the design plan (310 CMR 15.220(4)(h)).
3. This office is looking for the general pump specifications, pump/system curve and other
pump calculations to be provided to ensure the pump is sized adequately (310 CMR
15.220(4)(r)). Additional pump specification information is required. An example of
general septic system pump specifications/calculations is attached for a reference.
4. The pump chamber detail appears to specify two different model pumps. Barnes 3SE-1,
and Barnes SEV-511. Please indicate the correct pump that is being proposed.
5. The storznwater basin to the west of the leach trenches still does not appear to be labeled.
