A company’s active operation depends on its engineering department. One of the departments in this area is maintenance, which is responsible for keeping the machinery functioning smoothly. Maintenance work includes both the upkeep of manufacturing machines and utility maintenance. Utility services are an essential feature of every industry’s engineering department’s maintenance sector. Substations, generators, pumps, ETP (Effluent Treatment Plant), water treatment plants, compressors, and other utility services equipment are often used. Chemical, RMG (Ready-Made Garment), pharmaceutical, and other industries have different utility services. These companies provide utilities to the entire industry as well as install, maintain, and repair machinery. For this study, data were acquired from the engineering departments of various Bangladeshi industries’ utility services. We can wrap things up with a basic chunk. In terms of boilers, the chemical industry has employed larger capacity boilers than the clothing and pharmaceutical industries. The size of the industry and the rate of production are the most important factors. The bulk of compressors used in Bangladesh, according to surveys, are made in Germany and the United States. The great majority of generators used in Bangladesh are also built in the United States. According to estimates, the bulk of water treatment plant equipment used in Bangladesh is made in India or the United States.
