A manhole is basically the opening to confined spaces that are underground. It provides an access for carrying out inspections, maintenance work, adjustments of valves or making connections. These have a lot to do with sewers, water, electricity, gas, district heating and storm drains. The Sewer Manholes are also known as utility holes, inspection chambers, cable chambers, access chambers, maintenance hole or simply confined spaces. But these openings cannot be left open and have to be covered with proper manhole covers. These are flat plugs and are especially designed by the professionals for preventing unauthorised or accidental admission to the manhole.
