Manholes, which are increasingly termed maintenance holes, serve a useful purpose: they are the openings, or access points, that lead down to an underground public utility, such as a sewer or a drainage system. Engineers, laborers and inspectors use them for the purpose of inspecting, cleaning, repairing and maintaining utilities.
A manhole cover makes it easy for workers to remove then and enter the manhole to carry out trenchless rehabilitation by utilizing methods such as cured-in-place pipe (CIPP), thermoformed pipe and mechanical spot repair. A manhole can also be used to carry out trenchless inspection in order to find out problematic areas that can then be isolated and repaired. A manhole cover is made with different materials such as cast iron, ductile iron, concrete and in some cases, with glass reinforced plastic (GRP).
In addition to managing water runoff, storm manhole covers must also address environmental concerns. Cities are increasingly recognizing the need for sustainable practices in managing stormwater. Innovative designs now incorporate permeable materials that allow water to filter through the cover, reducing the immediate volume of runoff and promoting groundwater recharge. Such advancements represent a shift toward more eco-friendly infrastructure solutions, highlighting the balance that urban planners must strike between functionality and sustainability.
