An overall Analysis of a Composite Sewer Manhole Cover

In a world where business rivals are widely ongoing, different factors, such as quality, total cost, marketing,manufacturing methods, and environmental issues play important roles. Composite materials have successfully passedtheir mission in various fields; now there is an ideal opportunity for these materials to step up and get into philanthropicusage. Their long-lasting resistance against corrosion and humidity as well as their high strength make them a noblesolution to be used in sewerage. Therefore, many pipes, manholes, covers, and containers were manufactured utilizingcomposite materials and replaced by old metallic equipment recently. One main problem is the cost of sales that shouldbe competitive on a large scale. In this study, a comparison between different types of composite sewage manhole coversversus cast iron ones has been made by the FEM method. Ease in manufacturing also makes it possible to examinedifferent types of geometries. Finally, it was concluded due to many factors composite manhole covers are preferred tocast iron covers.
