How is the linear loading rate expressed?

The linear loading rate is primarily expressed in terms of gallons per day per linear foot because it measures the flow of effluent along a linear surface, such as a drain or trench. This metric indicates how much liquid can be effectively absorbed or treated by a specific length of the absorption system within a day. By using linear feet, professionals can assess the performance and requirements of the system in relation to its design and the flow rates of wastewater. This method provides a clear understanding of how effectively the system can manage wastewater over its length, which is crucial for ensuring proper treatment and preventing issues such as saturation or overloading.
