Wastewater problem is a never ending hot issue since fast growing industries in developing countries have serious impact on wastewater contamination. A wastewater model was performed using a linear approach corresponding with three elements (lead, copper and zinc) and water parameters (BOD, COD, TSS, pH and temperature) at three stations with respect to food stalls, boarding houses and laboratories area in academic campus. The samples were collected at six different times considering the busiest academic activities and student long break. The linear approach using ANOVA showed that water pH gave no impact on lead concentration at all stations. The Pearson correlation performed very strong relationship between copper and zinc concentrations at station with crowded food stalls. The Univariate General Linear Model with Post Hoc test in Tukey HSD and LSD modes showed significant difference of copper concentration between foodstalls area and boarding houses region.
