Storage and maintenance of pathogens is a costly and time-consuming affair, the recent study indicated that most of the pathogenic bacteria can be stored for several months at room temperature in sterile tap water without any hustle.

For short term storage yes. Still for longer term you want to make glycerol stocks that you whack in a freezer.
No, it is not recommended to use sterile tap water to store pathogens in a microbiology laboratory. Water, even if sterile, can easily become contaminated, and some pathogens can survive and grow in water environments. Water may not provide the necessary conditions for preserving pathogens effectively. It is better to use specialized media or culture media designed for pathogen storage. Following established laboratory protocols and guidelines is important for sample safety and integrity.
