Begin by understanding the necessity of a septic system in a rural residential construction project where municipal sewage is unavailable. The system typically comprises a septic tank, a distribution box (often referred to as the 'brain'), and a septic field with multiple trenches. Assess the site's topography to ensure adequate elevation differences for a gravity-fed system, which is crucial for efficient waste flow. For example, the septic field in the video is approximately 75 feet long and contains four trenches spaced about 10 feet apart, positioned lower than the house and the septic tank to utilize natural drainage.
