WASTEWATER TREATMENT AND REUSE FOR SUSTAINABLE WATER MANAGEMENT: A CASE STUDY IN DR. ADEREMI MAKANJUOLA HALL OF RESIDENCE (HALL 2)

The discharge of untreated wastewater in Dr. Aderemi Makanjuola Hall of Residence (Hall 2), Edo State University Iyamho has resulted in severe environmental degradation and public health risks. The failure of the sewage disposal structure has resulted in soil contamination of the leveled ground and serves as a breeding ground for mosquitoes and other foreign bodies, which are known to be a significant source of waterborne diseases. The lack of an adequate infrastructure for wastewater treatment, insufficient funding for wastewater management projects, and weak enforcement of environmental regulations has further resulted in more open wastewater disposal sites. This study addresses the ongoing discourse by implementing a wastewater treatment system (WWTS) for sustainable water management in Dr. Aderemi Makanjuola Hall of Residence, Edo State Univeristy, Iyamho, Edo State, Nigeria. Laboratory analysis is conducted to investigate the physio-chemical properties of domestic effluents, including pH, Total Dissolved Solids (TDS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), Total Suspended Solids (TSS), Chlorine Ion, temperature, and sulphate. The prediction model analysis was analyzed using statistical software tools, including Classification Learner App in MATLAB, and Markov Analysis. Parameters of treated wastewater samples were tested to check for accuracy, ROC/AUC, precision, recall, transition probabilities and states. Results from the model analysis showed that all parameters for the treated wastewater met the ASTM standards of water quality classification. The treated samples were categorized as moderate, indicating that they are suitable for non-potable applications. The Classification Learner App provided the best optimum model for precision with an accuracy of 79.2% compared to Markov chain model prediction. The Markov chain model predicted the water quality for six (6) weeks, showing that the water will have a near-probability of moderate throughout the predicted weeks. The study concludes that the wastewater treatment system (WWTS) is effective and the treated wastewater is suitable for non-potable applications.
