This document is the 48" Polypropylene Basin Minimum Angle Chart. A detail shows the basin with descriptions, adapter size chart and notes.

The top view detail shows the 3 stub 18” ADS HP dual wall locations with angles.

The adapter size chart lists adapters from size 12”-12” to 36”-36” with 48” HP MH degree values.

Notes state to measure the angle between the pipe runs directly to the storm drain plans for each structure location. Confirm minimum angle requirements. When recording the measured angles be sure to measure the angles in a clockwise direction and label the angle positions starting at the 12 o’clock position.
