The ndersigned hereby certify that the Sewage Disposal System ( ) constructed;
( repaired:
by_ Iii 1 L O
located at LZ-1 ;a JVV b LL L 1�r��tiG
was installed in conformance with the North Andover Board of Health approved plan,
System Design Permit# dated_ , with an approved design
flow of 44� gallons per day. The materials used were in conformance with those
specified on the approved plan; the system was installed in accordance with the provisions
of 310 CMR 15.000, Title 5 and local regulations, and the final grading agrees
substantially with the approved plan. All work is accurately represented on the As-built
which has been submitted to the Board of Health.

tank will not have required 9" of cover which appears to be an issue related to the septic
system design and would be difficult to correct during construction phase.

Comments:
Site topography does not appear to jive completely with design plan. Approved design plan
indicates soil absorption system should be raised higher than current grade by about 2' and
this is not the case. Elevations of septic system are all accurate which leads to conclusion
that original site topography might not be accurate. 9/24/03.
Final grading inspection on 10/01/03 indicates final grade over soil absorption system is as
per approved plan.
