Some important factors to be considered for designing a vacuum system are type and size of the chamber, ultimate pressure required for the process, facilities needed in the system, amount of gas or vapor load and cost involved. These parameters are presented in this article. In addition to these requirements, factors to keep the laboratory environment safe for workers are also discussed. Vacuum system design plays a vital role in the recent development of science and technology. Its applications include in the field of thin films, semiconductors, spectroscopy, surface science, nano technology, material science and processing. Beside all these, application of vacuum technology at low temperature, chemical industry and in particle accelerators has increased the impotence of proper vacuum system design. This write up also includes some important points for designing a vacuum system like  useful  materials for vacuum vessels and pipes, chambers, gas flow, conductance, joints in vacuum systems, cleaning of vacuum components, sealing techniques, leak testing techniques, traps and baffles. The brief description of instrumentations and facilities required like optical windows, electric feed through, gas metering devices, heating cooling arrangements, valves, pumps etc. are presented. A case study is also included.
