RE:Sewage Disposal System Installation

Dear Mr. Murphy:
Coastal Engineering Company, Inc. performed inspections of the sewage disposal system installation at the above
referenced location in February 2022. On February 22, 2022, we witnessed the soils in the excavation for the soil
absorption system and observed that the clean sand continues to a depth greater than four feet below the bottom of
the soil absorption system, as required by a note on the plan. We subsequently inspected the sewage disposal system
installation after it had been installed, prior to final covering. A second building sewer from the south wing of the
dwelling was awaiting installation by the plumber.We were not notified when the connection had been completed and
we did not inspect that section of building sewer installation. At the time of our inspection raising of the access covers,
covering of the system components, and final grading had not been done.
Based upon our inspections, it is our determination that the sewage disposal system was installed in substantial
conformance with the approved plans. We did not conduct an inspection of the sewage disposal system installation
after the system was covered, access covers raised, and final grading had been completed.
Please contact me directly if you have any questions.
Very truly yours,
