What is the maximum size allowed for a raised filter bed?

The maximum size allowed for a raised filter bed, which is commonly referenced in septic system regulations, is 600 square feet. This size is determined based on factors such as infiltration rates, soil characteristics, and the need to adequately treat effluent before it disperses into the surrounding environment. A raised filter bed that exceeds this size without adhering to the proper guidelines can lead to inefficiencies in wastewater treatment and potential environmental hazards. It's vital for installers to adhere to this limit to ensure that the septic system functions effectively and complies with local regulations, thereby protecting both public health and the environment.
