Andover Board of Health"By-Laws" if the following is addressed:
1) Plan Soil Logs do not match Board of Health records.
2) Show or provide a note indicating location of water service.
3) Revise for a 96.94 water table.
4) Provide cross section of leaching facility NA 8.02w.
5) Provide a note on abandonment of old system.
6) Provide a note to replace outlet tee in septic tank and install gas baffle.
7) Provide an inlet tee in D-Box 232(3)a.

Re: 517 Johnson Street,North Andover, Septic system design
Dear Sandra:
Enclosed are revised septic system design plans for the above reference property. The
following changes have been made.
1. The water service location has been added to the plans.
2. Leach system cross sections have been added to the plans.
3. A note has been added indicating that a tee shall be installed on the inlet pipe for the
distribution box.
4. The existing septic system location has been shown on the plans.
5. Note 12 indicates that new tees and a gas baffle shall be installed on the existing tank.
If you have any questions regarding the information submitted, please do not hesitate to
contact this office.
