Getting More Bang for Your Buck with Manhole Inspections

Posted by Venay Sehgal Bhatia on Jul 6, 2018

Manhole Inspections White PaperInspecting 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. Envirosight’s 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 that exist 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. There are an estimated 20 million manholes in the United States, and more than half were installed before 1960. Moreover, a study cited in the paper showed that in some cases up to 90% of I&I present 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 and by laying out the numbers.

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 inspection solutions 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.
