In which category does an onsite wastewater system fall if it has not received final construction approval?

An onsite wastewater system that has not received final construction approval is categorized as a Probational System. This designation indicates that while the system may be partially constructed or operational, it has not yet met all regulatory requirements necessary for full approval. This classification is crucial because it implies that the system is still under evaluation and may require adjustments or modifications to comply with state regulations.

Understanding this classification helps ensure that no system is improperly utilized before it meets health and safety standards. Such a focus on compliance is vital in the management of onsite wastewater systems to protect public health and the environment. The other categories, while relevant to wastewater system classifications, do not accurately reflect the status of a system lacking final approval, which is why they do not apply in this context.
