What is a primary reason to understand state and local codes regarding septic systems?

Understanding state and local codes regarding septic systems is crucial primarily to ensure compliance for safety and environmental protection. These regulations are established to safeguard public health and the environment by dictating proper septic system design, installation, and maintenance practices. Adhering to these codes minimizes the risk of system failures, which can lead to contamination of groundwater and surface water, posing risks to human health and local ecosystems. Compliance not only protects the environment but also avoids legal issues and potential fines for non-compliance, making it essential for anyone involved in septic system installation or maintenance to be well-versed in the relevant regulations.
