Peak hours occur at 12.00-14.00 except in the dormitory at 06.00-08.00 and cafeteria at 10.00-11.00. The peak factor of used water ranges from 1.56 to 3.13. From the measurement results obtained the wastewater from dormitory wastewater of 212.8 m<sup>3</sup>/day; lecture building 491 m<sup>3</sup>/day; student facilities 32.4 m<sup>3</sup>/day; offices 245.4 m<sup>3</sup>/day; worship 50.4 m<sup>3</sup>/day; cafeteria 109.2 m<sup>3</sup>/day; sports facilities 8.7 m<sup>3</sup>/day; laboratory 282 m<sup>3</sup>/day; corral 27 m<sup>3</sup>/day; and pool bus 34.7 m<sup>3</sup>/day respectively.
