The purpose of this study is to supply preliminary data of the frequency of used low-tank type toilets in residential houses.
As the ratio of detached house is 31.9%(3,984,954) in Korea, the use of rainwater for low-tank type is more effective to reduce
the amount of tap water used. To obtain the regression curve on the frequency of used toilets, the 16 students who have
different family types(male and female ratio, family constituent members) carried out the questionnaire for 35days. It is
investigated total frequency of used toilets for 18days, and then is examined frequency of used toilets for 17days by male and
female respectively. The characteristics of rainwater is investigated using weather data of Weather forecasters from 2000 to 2003
in Korea. The decision of rainwater tank capacity is affected by the period of water shortage. It is no rain during 39days in
2000, 13days in 2001, 25days in 2002, 18days in 2003 respectively, Pusan.
The frequency of used toilets is affected by the proportion of males to females. Specially, It was depended on the total used
toilets by the frequency of female used toilets. As the rainwater tank capacity can be calculated by frequency of used toilets and
the period of water shortage, the rainwater tank could be made as economical construction cost
