PLUMBING GENERAL NOTES:

1. THE OWNER WILL CONDUCT A WATER ANALYSIS (TESTING)

OF THE EXISTING PONDING OF WATER IN THE CRAWLSPACE,

SPECIFICALLY TO TEST FOR HUMAN WASTE/SEWAGE TO

CONFIRM WHETHER THE PONDING WATER IS GROUND WATER

OR SANITARY WASTE WATER FROM UNDERGROUND PIPE

BREAKAGE. REPORT TEST RESULTS TO OWNER/ENGINEER. IF

SANITARY WASTE WATER IS DETECTED, COORDINATE WITH

ENGINEER FOR FURTHER INSTRUCTION. THIS

DOCUMENTATION SHALL BE AVAILABLE TO THE CONTRACTOR

PRIOR TO THE START OF THE SCOPE OF WORK SHOWN ON

THIS SHEET.

2. THE OWNER WILL PERFORM CAMERA SNAKE INSPECTION

OF ALL STORMWATER AND SANITARY PIPING BENEATH THE

CRAWLSPACE SLAB TO A POINT AT MINIMUM 5’ BEYOND

CRAWLSPACE PERIMETER. THE CAMERA SNAKE SHALL HAVE

A LOCATOR DEVICE TO MARK UP THE SLAB WITH SPRAY PAINT

TO IDENTIFY LOCATIONS AND ROUTING OF THE SANITARY

SYSTEM BELOW THE SLAB. THE CAMERA INSPECTION SHALL

DOCUMENT LOCATIONS OF EXISTING BELOW MUD SLAB PIPE

ROUTING AND ALSO REPORT IF (AND WHERE)

REVERSE-SLOPE OR BROKEN PIPE CONDITIONS EXIST. THE

DOCUMENTATION OF EXISTING CONDITIONS SHALL BE

AVAILABLE TO THE CONTRACTOR PRIOR TO THE START OF

THE SCOPE OF WORK SHOWN ON THIS SHEET.
