Briefly, researchers revealed harmful pathogens might enter the water system from urine, faecal, or stool of the infected people or animals , .These wastes are then sourced through plumbing systems, which are mainly from hospitals, quarantine facilities, residential buildings, sewage, landfill, and drainage water thus, contaminating the wastewater treatment system ().

A 30% rise in fresh water demand is possible by 2030 if the current projection is well matched with population growth. Approximately 80% of wastewater without prior treatment is discharged into water resources such as groundwater and seawater. Thus, these water sources are being polluted and are deteriorating in parallel.
