Flushing Effect Depending on the Installation Density and Opening Order of Fire Hydrants in Water Supply Networks

In this study, using the WaterGEMS model, hydrant installation density in small blocks and flushing effect according to opening order were analyzed for various scenarios results compared. The analysis revealed that even case of conventional flushing, same could be achieved by reducing number openings up 20% (30 → 24) when optimal was determined through preliminary simulation, rather than simply all hydrants at random. I knew it work. addition, confirmed as increased, satisfaction extension increased. particular, installed target area approximately 30, most pipe extensions. proposed methodology can used establish a detailed implementation plan standards maintenance waterworks network facilities mandate water supply network.
