THE DOWNSTREAM END OF PIPE. CONTRACTOR SHALL PROVIDE EQUIVALENT
CONCRETE ANCHORS TO MEET THE MINIMUM WEIGHT REQUIREMENTS SHOWN.
ANCHORS SHOULD BE SIZED APPROPRIATELY WITH REGARD TO WEIGHT
REQUIREMENTS AND METHOD OF INSTALLATION.
3. ADDITIONAL ANCHORING MAY BE REQUIRED FOR EMPTY PIPE INSTALLED BELOW
THE SEASONAL GROUND WATER TABLE. MINIMUM COVER DEPTH OVER PIPE AS
SHOWN IN TABLE MUST BE ACHIEVED -OR- APPROVED PIPE ANCHORING SYSTEM
