Which is a disadvantage of a conventional septic system?

A conventional septic system is designed to treat wastewater from individual households, typically requiring a significant amount of land to accommodate both the septic tank and the drain field. The drain field, which is vital for the dispersal and treatment of effluent, needs to be properly sized and located to protect groundwater and ensure effective biological treatment. This requirement for a large area can be a significant disadvantage, especially in densely populated regions or smaller properties where space is limited.

In contrast, low maintenance cost, ease of customization, and high efficiency are generally considered advantages of conventional septic systems, depending on the specific installation and care involved. However, the requirement for extensive land usage remains a critical factor in considering the practicality and feasibility of installing a conventional septic system.
