Which factors limit the type of on-site sewage disposal system that can be used?

Soil and site conditions play a crucial role in determining the type of on-site sewage disposal system that can be implemented. The characteristics of the soil, such as permeability, texture, drainage capacity, and depth to groundwater or bedrock, directly affect how effectively a sewage system can function. Different systems require specific conditions; for instance, certain systems may not perform well in heavy clay soils that retain water or sandy soils that allow too rapid drainage, leading to potential contamination.

Additionally, site conditions, including the slope, proximity to water bodies, and available space for the system, impact the design and installation of the sewage disposal system. Assessing both soil type and site characteristics helps ensure that wastewater is treated effectively and does not pose a risk to public health or the environment. Understanding these limitations is essential for designing an appropriate and compliant sewage disposal system that operates efficiently over time.
