BOARD OF HEALTH AGENT AND ENGINEER FOR INSPECTION.
4. ALL SANITARY DISPOSAL SYSTEM PIPING TO BE 4" SCHEDULE 40 PVC, UNLESS
OTHERWISE NOTED HEREIN.
5. IF THE SOILS ARE FOUND TO NOT BE CONSISTENT WITH THE TEST HOLE DATA,
EXCAVATE UNSUITABLE MATERIAL TO THE "Cl HORIZON" IF REQUIRED, FOR A
HORIZONTAL DISTANCE OF 5' SURROUNDING THE LEACHING FIELD, AND REPLACE
WITH CLEAN SAND PER 310 CMR 15.255 TO THE TOP ELEVATION OF THE SAS.
6. INSULATE ALL PIPES AGAINST FREEZING AS REQUIRED WHEN LESS THAN 3' OF
COVER.
7. THE SEPTIC SYSTEM DESIGN DOES NOT INCLUDE GARBAGE GRINDER DISPOSALS.
8. CAUTION: THE CONTRACTOR SHALL CONTACT DIG SAFE (AT 1-888-DIG-SAFE)
AND UTILITY COMPANIES TO LOCATE ALL EXISTING UTILITIES, AT LEAST 72 HOURS
BEFORE THE START OF CONSTRUCTION. THE CONTRACTOR SHALL DETERMINE THE
