Population Equivalent is a measure used in wastewater treatment to quantify the organic load generated by a population, which is crucial for designing and managing treatment facilities. The flow rate commonly used to express Population Equivalent is 100 gallons per person per day. This figure represents an average daily water use per individual, accounting for domestic water consumption that contributes to sewage generation.

Using 100 gallons per person per day provides a practical baseline that reflects typical household water usage patterns, including activities such as bathing, cooking, and cleaning. This standardized measure helps engineers and planners calculate the total expected wastewater flow from a given population size, facilitating the design of treatment systems that can adequately handle the anticipated load.

Other flow rates listed may represent different contexts or scenarios but do not serve as the standard for Population Equivalent calculations. For instance, a higher rate might be used in specific industrial contexts, while lower rates could apply to water conservation scenarios.
