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.
Moreover, lidless dustbins can help prevent organic waste accumulation. In the absence of a lid, odors from decaying food and other organic materials can dissipate more easily, reducing the chances of attracting pests such as rats and insects. This is particularly crucial in cities where sanitation is a major concern. By limiting the attraction of pests, lidless bins can contribute to a healthier environment for both humans and wildlife.
