What must be included in a septic system design plan?

In a septic system design plan, a site evaluation and dimensions are crucial components. This information ensures that the system is appropriately sized and positioned based on factors such as the soil type, groundwater level, and proximity to existing structures or water sources. The site evaluation helps determine suitability for a septic system installation, assessing aspects like drainage patterns, slope, and any potential environmental impact. Including precise dimensions allows for accurate planning of the system components, ensuring that the installation will function effectively and comply with local regulations. Together, these details contribute to a functional and sustainable septic system that meets health and safety standards.
