What happens if the riser is not adequately elevated above ground?

If the riser is not adequately elevated above ground, it creates a potential for flooding. The primary function of a riser is to provide access to the septic system while ensuring that wastewater and effluent are directed away from the living areas. When the riser is too low, it can collect rainwater or groundwater, which may cause the septic system to become inundated. This flooding can lead to backups or overflows, compromising the system's ability to function properly. Proper elevation helps to ensure that surface water does not seep into the septic tank or drain fields, protecting the system from contamination and failure.
