1. The sanitary sewage disposal system shown hereon shall be CONSTRUCTED IN
ACCORDANCE with the requirements of 1995 310 CMR 15 (TITLE V) of the State
Environmental Code and local Board of Health regulations. Any NIODiFICATION
TO THIS DESIGN must be approved in writing by the engineer and the local Board
of Health prior to implementation.
2. Contractor shall verify and check the BENCHMARK as shown on this plan prior to
construction of the proposed system.
3. Notify the local Board of Health when the system is ready for INSPECTION, prior to
any backfiliing. If CONFIRMATION OF CONSTRUCTION is required by an
engineer, notify this office 3 days prior to any backfilling.
4. DEEP TEST HOLE INFORMATION indicates soil condition, percolation rate, and
water table elevation at the time and location of actual testing and should be verified
at the time of construction. The contractor shall notify the local Board of Health if
GROUNDWATER or PERCHED WATER is encountered at a higher elevation than
indicated on this design plan.
5. TOP OF FOUNDATION, BASEMENT and FIRST FLOOR elevations may be raised
but NOT LOWERED without the consent of the engineer.
6. Unless specified in the Basis of Sanitary Design, this system is NOT designed for the
use of a garbage grinder or other high water usage devices.
7. Where the building sewer pipe exits the foundation ABOVE the basement floor, an
effluent or grinder pump conforming to 310 CMR 15.229 may be used to discharge A
VOLUME OF LESS THAN 25% OF THE DESIGN FLOW from any basement
facilities to the septic tank.
S. If any components of the proposed system are specified as HEAVY. DUTY, those
components shall conform to all state & local requirements for ASSHTO H-20 loading.
9. The SEPTIC TANK shall be 1500 gallons minimum, unless otherwise specified on this
design plan, and fitted with PVC schedule 40 INLET TEE and OUTLET TEE WITH
GAS BAFFLE of proper length. Septic tankconstruction shall conform to 310 CNIR
15.226. The SEPTIC TANK OUTLET COVER is to built up to within 6" of the
finished grade unless otherwise specified on this design plan.
10. SEPTIC TANK and DISTRIBUTION BOX shall be placed on a 6"- minimum
compacted GRAVEL BASE to prevent heaving or settling. ALL -JOINTS MUST BE
WATERTIGHT, sealed with asphalt cement or other cement suitable for that specific
component.
11. SOIL PREPARATION PROCEDURE FOR THE LEACHING FACILITY AREA shall
conform to 310 CMR 15.246 & 15.247.
12. Any EXCAVATION OF UNSUITABLE MATERiAL.designated on the plan shall
conform to Construction in Fill requirements as outlined in 310 CNIR 15.255 (1-6).
13. No HEAVY EQUIPMENT shall be run over the components or the prepared leaching
area during installation. RUBBER TIRE MACHINERY are not to be driven over the
prepared natural soil base or sand/stone bed during system installation.
14.' For proper performance, the septic tank should be INSPECTED annually and when
the solids and scum depth exceeds 113 of the 'liquid depth, or three years has elapsed
since the last pumping, the tank and the leaching pit (if any) should be pumped.
