The Standard says the intent of joint and connection testing is to identify those sewer joints, lateral connections and laterals that are not watertight and that can be successfully sealed by packer injection grouting.

The National Association of Sewer Services Companies (NASSCO) says the new standard can be utilised for the following applications:

  • Test all joints in a mainline segment
  • Test all service lateral connections from the sewer main to a predetermined distance up the sewer lateral.
  • Test all joints within a predetermined distance in laterals directly connected to manholes.
