This study evaluates the physical, chemical, and biological properties of wastewater—comprising domestic sewage agricultural drainage water—both before after treatment to assess efficiency applied processes. The physical properties, including total suspended solids (TSS) color, demonstrated significant improvements post-treatment, with TSS reduction reaching 91.4% color removal at 99.5%, indicating effectiveness ultrafiltration coagulation techniques. Chemically, dissolved (TDS) concentration decreased from 838.2 375.5 mg·L−1, aligning environmental standards ensuring suitability for irrigation. Additional reductions were observed in biochemical oxygen demand (BOD) chemical (COD), efficiencies 86.5% 83.7%, respectively, highlighting system’s capability reducing organic pollutants. Biologically, process achieved 99.9% both Total Coliform E. coli, meeting world health organization (WHO) guidelines microbial safety. water quality index (WQI) analysis classified treated “Excellent” category, demonstrating an overall enhancement quality. Beyond these performance evaluations, this introduces a novel approach by employing conventional techniques on blended water—operated under real operational conditions achieve safe sustainable irrigation reuse. hypothesizes that synergistic integration sodium hypochlorite disinfection—without relying treatment—can significantly enhance
