摘要:On the basis of the registered indications of the water meter, a study on the size and variability of water consumption on the WULS campus in the academic years 2012/16 is presented.The average specific water consumption at a time when classes are implemented amounted to 26.6 dm3 per student per day for full-time studies student and 19.7 dm3 per student per day for the student part-time studies.During the holiday season, the rates are lower at 18.4 and 11.8 dm3 per student per day, respectively.These ratios were determined without taking the water consumption in the dorms into account.The daily peaking factor amounted (Nd) to 1.36, while the hourly peaking factor (Nh), reached 1.71.Within the week cycle, the highest water consumption was observed in Tuesdays and the lowest – in Sundays.The average Tuesday demands are 40% higher than the Sunday demands.The water consumption peaks during the day occur between 11 a.m.and 1 p.m.as well as 11 p.m.and 1 a.m.The hourly structure of the water distribution in the WULS-SGGW campus is similar to the weekend structure of water distribution in multi-family residential buildings, with the exception of the later occurrence of the evening summit.
