Getting More Bang for Your Buck with Manhole Inspections

Inspecting sewer lines can help you identify I&I sources and address any problem areas — but that’s not the only inspection you should prioritize. Modern manhole inspections could also save you high treatment costs and expensive regulatory action. A new white paper, Rethinking Manhole Inspection: A New Way to Reduce I&I Quickly and Cost-Effectively, outlines why the inspection of manholes can sometimes be more effective than pipeline evaluation and is gaining popularity within the industry.

The sheer volume of defect-ridden manholes in our sewer infrastructure, which are failing at a rate much faster than sewer pipeline, is proof enough that manhole inspections are critical now more than ever. Of the estimated 20 million manholes in the United States, more than half were installed before 1960. Moreover, one study showed that in some extreme cases up to 90 percent of I&I in a system came from failing manholes. Manholes are at a higher risk for inflow or infiltration than pipelines because they are subject to more surface stresses than sewer pipelines.

Municipalities can save money by addressing I&I-ridden manholes — not only in rehabilitation and repair costs but also by avoiding excess water treatment costs. The paper further discusses many other reasons why manhole inspections should take precedence and proves its effectiveness through industry examples.

The paper doesn’t stop at just showing why manhole inspections are critical; it also offers aid to individuals looking for guidance when navigating the many different manhole inspection solutions. The technology available for inspections has improved substantially over the last decade, making these products a worthwhile investment compared to the visual inspections of years past — if the right equipment is purchased. The paper discusses the many considerations municipalities and municipal contractors should keep in mind when evaluating different manhole inspection solutions.
