GENERAL ABSORPTION AREA NOTES
1. INSTALL CHAMBER UNITS IN ACCORDANCE WITH
MANUFACTURER'S RECOMMENDATIONS.
2. ABSORPTION BEDS SHALL NOT EXCEED 12' WIDE BY

THE BOTTOM OF THE ABSORPTION BED SHALL BE
LEVEL AND THE BOTTOM AND SIDEWALLS MUST BE
RAKED TO REMOVE ANY SOIL SMEARS INCURRED
DURING THE EXCAVATION. FAILURE TO DO SO MAY
REQUIRE THE CONTRACTOR TO REPLACE THE
ABSORPTION FIELD AT HIS/HER OWN EXPENSE.
4. DRAINAGE SWALES ARE TO BE PROVIDED ABOVE
AND AROUND THE FIELD, AS NECESSARY, TO
PREVENT SURFACE RUNOFF FROM ENTERING
ABSORPTION AREA.
5. NO EXCAVATION OF THE ABSORPTION FIELD IS TO
BE DONE DURING WET WEATHER AND USE OF
RUBBER TIRE VEHICLES OVER THE ABSORPTION
AREA IS STRICTLY PROHIBITED.
6. UNSUITABLE MATERIAL EXISTING WITHIN THE FIELD
SHALL BE EXCAVATED AND BACKFILL SHALL
CONSIST OF IMPORTED LOAMY SAND OR SANDY
GRAVEL. THE ENGINEER SHALL BE CONTACTED IF
BEDROCK OR GROUNDWATER IS ENCOUNTERED IN
THE EXCAVATION.
