Description

All construction projects require attention to detail and installing a sanitary sewer line is no exception. There are critical elements that consistently make or break a new installation project or a sectional field repair.

Effective pipeline inspections include: monitoring trench widths, inspecting pipe bedding materials, unloading, handling and storage of pipe on the construction site, adequate preparation of the trench bottom/foundation, bell holes, haunching/shovel slicing, pipe homing/jointing, backfill, compaction, connections to manhole structures, service/lateral connections, tapping new or existing mainlines and acceptance testing.  

1. Explain the differences between “Flexible” and “Rigid” pipe materials
2. Discuss the importance of proper pipe bedding and installation
3. Explain the necessity and differences in pipe inspection/testing 
4. Explore the frequency of testing and inspection vs. pipe material 

Acceptance testing methods commonly used are CCTV inspection, deflection testing, and low-pressure air testing.  Testing immediately after backfill completion is considered a best practice because it helps to identify any installation deficiencies before additional pipe is installed. 

Attend this session and discuss how continual testing/inspection as a job progresses improves adherence to good job site practices, increases contractor productivity and ensures compliance with manufacturer’s recommendations and municipal engineering plans.
