BACKFILLING
• Backfill and haunch per the ASTM D 2321 specification to prevent damage or failure of the inlet piping! Work in
and compact the material in the haunching area to provide complete contact with the pipe bottom and ensure
there are no voids. The material in the haunching area supports the vertical load applied to the pipe. Not
compacting the embedment material will allow excessive deflection of the pipe and potential failure. Compact to
70% STANDARD PROCTOR DENSITY or a 700PSI SOIL MODULUS.
•
Note: 6” pipefittings are not to be used with basins.
