NOTES
1) INSTALLER TO OBTAIN DISPOSAL WORKS PERMIT BEFORE STARTING WORK.
2) SEPTIC TANK TO BE PUMPED DRY AT TIME OF SYSTEM REPAIR AND CHECKED
FOR STRUCTURAL INTEGRITY. INSTALL PVC OUTLET TEE FITTED WITH GAS BAFFLE.
3) ALL COMPONENTS INSTALLED SHALL MEET THE MINIMUM REOUIREMENTS
OF MASSACHUSETTS TITLE 5 SEPTIC CODE (310 CMR 15).
4) INSTALLER TO VERIFY LOCATIONS OF ALL UNDERGROUND UTILITIES
BEFORE EXCAVATING FOR SYSTEM.
5) EXISTING LEACH PIT TO BE PUMPED, COLLAPSED. AND REMOVED.

STABLE BASE THAT HAS BEEN MECHANICALLY COMPACTED AND ON TO WHICH
SIX INCHES OF CRUSHED STONE HAS BEEN PLACED TO MINIMIZE UNEVEN SETTLING
DESIGN CALCULATIONS
DESIGN FLOW: 3 BEDROOMS X 110 GPD = 330 GPD
SEPTIC TANK: 330 GPD X 2 DAYS = 660 GALLONS
USE EXISTING 1000 GALLON SEPTIC TANK IF IN SOUND STRUCTURAL
CONDITION. IF NOT, INSTALL 1500 GALLON SEPTIC TANK (MINIMUM ALLOWED)
DISTRIBUTION BOX: USE 3 OUTLET D -BOX.
SOIL ABSORBTION SYSTEM: A 29 Ft x 10 Ft x 2 FL LEACHING GALLERY CAN LEACH
Abot = ( 29 x 10 ) = 290 sF
Asdw = ( 29 + 29 + 10 + 10 ) x 2 = 156 sf
ALot = 446 sF
VL 0.74 x 446 = 330.04 GPD
USE A 29 FE x 10 Ft x 2 FE GALLERY. VE = 330.04 GPD > 330 GPD REQUIRED
