Calculations of Quantitative Requirements of Hot Spring
Water in Accord with Accommodation Capacity
Masayuki HAMADA+Abstract
Empirically one liter per minute is considered as the hot spring ﬂow rate su$cientfor one hotel guest in any hot-spring resort. A rough comparison between the total
number of lodgers in hot-spring resorts and the total ﬂow volume of hot springs indicatesthat the supply could be feasible. By using “the management manual for hygiene inpublic baths”, the author can estimate the accommodation capacity according to thesurface of baths in a hotel. This area also gives the ﬂow rate of hot spring to keep thebaths in constant temperature appropriate for bathing. The turbidity standard relevantto the measures against “Legionella pneumophila” shows the necessary quantity of hot
spring water to keep the baths clean. The relationship between temperature, ﬂow rate
and turbidity of hot springs in baths are sometimes mathematically insoluble. But what
seems the best possible way for the author, is just wash oneself before bathing.
