Which action should NOT be taken after a disaster to address wastewater issues?

Pumping an onsite system or septic tank empty when the ground is saturated is not advisable after a disaster because it can lead to further environmental contamination and health hazards. When the ground is already saturated, there is limited capacity for additional liquids, which can cause untreated sewage to backflow or overflow. This can exacerbate the situation, spreading pollutants and pathogens, and increasing risks to public health and the environment.

In contrast, having an onsite system inspected by a licensed contractor is crucial for ensuring that the system is functioning properly and safely after a disaster. Securing areas affected by a sewage spill is essential for preventing unauthorized access and potential health risks. Considering alternate means of sewage disposal is also a proactive step to manage any immediate risks while assessing the situation and planning for long-term repairs. Each of these actions supports effective management of wastewater issues in post-disaster scenarios, whereas emptying a septic system under saturated conditions can complicate the recovery efforts.
