Domestic waste is the most waste produced every day by varioushousehold activities that have a level of COD (chemical Oxygen Demand), BOD (Biological Oxygen Demand), TSS (Total Suspended Solid), pH, Temperature, Oil and E. Coli which are very high and harmful to the environment. Therefore this problem cannot be ignored and requires special attention so that water pollution can be minimized by using the Communal WWTP (Water-waste Treatment Plant) management model. This is done by treating the inlet-outlet water discharge factors, giving biofilter media, and administering decomposing bacteria. Data analysis was performed by using a three way ANOVA statistical model to prove whether the influence was partial or simultaneous. The conclusions the sanitation modeling behavior are as follows: 1) water discharge, media, bacteria and their interaction do not affect the pH of the water; 2) water discharge and bacteria affect the water temperature, while the media and their interactions do not affect the water temperature; 3) water discharge, media, bacteria affected BOD, while the interaction did not affect BOD; 4) water discharge, media, bacteria affect COD, while the interactions do not affect COD; 5) water discharge, media, bacteria affect oil, while the interactions do not affect oil; 6) water discharge and bacteria have an effect on E. Coli, while the media and their interactionshave no effect on E. Coli; 7) water discharge affects Temperature, BOD, COD, TSS, Oil, and E. coli; 8) media affect BOD, COD, and Oil; 9) Bacteria affect temperature, BOD, COD, Oil and E. coli; 10) Interaction between media * water discharge * bacteria only affects TSS; 11) pH parameter of water cannot be affected by water discharge, media or bacteria.
