What is typically a consequence of a failed septic system?

A failed septic system can lead to a variety of negative consequences, one of which is a decrease in property value. When a septic system is not functioning correctly, it can create health and safety hazards due to potential wastewater contamination. This not only poses a risk to the occupants of the property but can also affect neighboring properties and the local environment. As a result, prospective buyers may be deterred from purchasing a property with a failing septic system, leading to a reduced market value. This diminished desirability can have a long-lasting impact on the property owner's financial investment.

In contrast, the other options do not accurately reflect the consequences associated with a failed septic system. For example, the notion of an increased water supply is unlikely, as a failing system could often lead to leaks and a loss of water rather than an increase. Improvements to landscape aesthetics and enhanced biodiversity are also not typical outcomes of septic system failures; instead, such failures can lead to environmental degradation and unpleasant odors, detracting from both the landscape and the local ecosystem.
