Characteristics of Wastewater: Physical Chemical, Biological
Physical Characteristics of Waste Water. Color: Fresh domestic sewage exhibits a grey coloration, bearing a resemblance to a diluted solution of soap. As time elapses, the process of putrefaction initiates, resulting in a darkening effect. Septic sewage typically exhibits a predominantly black or dark hue.
