What is the purpose of conducting a flood plain assessment during OSSF installation?

Conducting a flood plain assessment during the installation of an On-Site Sewage Facility (OSSF) is crucial for environmental protection, particularly to prevent the contamination of water sources during flood events. Flood plains are areas that are susceptible to flooding and during such events, sewage systems can be overwhelmed or inundated, which can lead to the release of untreated or partially treated effluent into nearby water sources. This not only poses a risk to public health but can also lead to significant environmental degradation. By performing a flood plain assessment, installers can identify potential risks and make necessary adjustments to the system's design or location, ensuring that it is situated away from areas that could experience flooding. This proactive measure safeguards both the ecosystem and the health of the community in the event of significant rainfall or flooding.
