Polypropylene Pipe Used For Maine Combined Sewer Overflow Project

January 2012, Vol. 67 No. 1

The Grondin crew had to be a little creative in making the connection because it was a very tight fit. They picked up both pipe sections, let them touch and then lowered both into place. They used a steel band coupler and did a concrete collar around it.

To backfill the trench, most of the material used was existing native soil. Crushed stone was laid as a bed for the pipe and about a foot of cover directly over the top the pipe.
