Study of water usage fluctuation in apartment for university student residences

Water usage is inseparable from the water quality, its accessibility and rapid urban development followed by an increase in facilities and infrastructure. This study aims to determine how the use of clean water in apartment buildings based on its designation is for students in university area. This observation was carried out by comparing secondary data on 24 hours/7 days fluctuations in water usage from six apartments. Observation results showed that peak hours on weekdays averagely occur between 06:00 - 08:00 am in the morning and 06:00 -08:00 pm at night, while the amount of water used per day on weekdays was higher than on weekends. The percentage water usage at peak hour for the six apartments, on weekdays and weekends were 7.24 - 7.24; 7.54 - 8.04; 9.01 - 8.53; 7.56 - 7.6; 8.53 - 8.63; 9.48 - 8.69 respectively. Due to their similar percentage, it could be concluded that those apartments have the same type of activity. These results could be used in designing of water reservoirs in typical apartments of university student residences.
