The sewer lines beneath Cal Poly Pomona will be cleaned and inspected starting on Monday, June 11.
Crews from Innerline Engineering will flush out the pipes using water from powerful jet nozzles before sinking a closed-circuit TV monitor into the lines to check for any cracks or damage in the pipes or a buildup of deposits that could cause a blockage.
Camera operators will look for deposits that include gravel or grease blobs and signs of infestation by vermin and cockroaches. If pipe damage is detected, the contractor could conduct repairs.
Workers will access the sewer lines through manholes dotted across the campus. Some of the manholes are located close to buildings. The bulk of the sewer line cleaning and inspection in the academic core of campus is scheduled to finish before the start of summer session classes.
When the work is completed in late June, the university will receive a report from Innerline on the condition and composition of the pipes and recordings of the visual inspection. The project also aims to bridge any gaps in utility mapping of the campus by the Department of Facilities Planning & Management.
One aim of the sewer line cleaning and inspection project is to head off any potential sewer problems.
