Certification of a Title 5 System Installation
Location of System: 757 Willow Street South Yarmouth, MA
Map 42 Lot 119
Type of Inspection: Title 5 System Installation Inspection SEN 2 2023
Date: September 25, 2023 HEALTH DEPT.
I, David D. Flaherty Jr., Registered Sanitarian, duly licensed in the Commonwealth of
Massachusetts,do hereby certify that I have visually inspected the system installation and certify
that the system, as constructed, was installed within substantial compliance and generally
conforms within acceptable tolerance to the regulations set forth in 310 CMR 15.000 (Title 5)
and the Town of Yarmouth Board of Health regulations. •
All unsuitable soils (A & B Horizons) were removed as per plan. Any fill brought in was clean
medium sand as per Title 5.
Soil removal inspection was on 8/14/2023. Final inspection was on 8/15/2023.
At the time of Final Inspection it was determined that the tanks were installed at higher
elevations than per plan; the primary septic tank was 10" higher and the secondary septic
tank/pump chamber was 3". The primary septic tank was re-installed as per plan. To resolve the
ST/PC without extensive re-construction, the installer drilled a new inlet. I calculated the
gallonage difference as follows based on interior measurements:
Secondary Tank/PC: 11.75'L x 5.17'W x 3.25'D x 7.5' G/SF= 1,481 gallons
Subtract 500 gallons from P/C side of ST/PC=981 gallons (>440 GPD req.)
The gallons from the septic tank side of the ST/PC will still have >440 GPD as required by a
secondary tank in series.
Such certification shall neither be misconstrued as a guarantee that the system will operate
satisf rily nor c rtification of alterations after inspection.
