Study on fluctuation of water consumption at education activity building (Universitas Pendidikan Indonesia as a case study)

Abstract

The aim of this research is to know the pattern of clean water consumption at Universitas Pendidikan Indonesia (UPI). The study was conducted in three lecture buildings. Observations and measurements are made based on changes in water level reservoir once every hour for 10 days respectively. The first building was a FPOK building consisting of 5 floors with 37 staff rooms and 19 lecture halls. The second is the FPBS building consisting of 5 floors with 1 basement with 39 staff rooms and 33 lecture halls. The third is the FPEB building consisting of 6 floors with 10 laboratory rooms and 20 lecture halls. All buildings are equipped with men's and women's toilets on each floor. The result show that the peak hour factor for the three buildings, respectively, is 2.269; 1.909; 3.09 and the maximum daily factor is 1.058; 1.079; 1.06. The highest peak hour factor occurred in the FPEB building because the water use every hour is quite high and tend to occur during rest and prayer. Significant differences occur in the peak hour factor rather than the maximum daily factor because of the same characteristics of the three buildings with different hour-to-hour but same day-to-day activities.
