Episode notes
Plan For One Acre Minimum
- Aim for about one acre minimum when planning a septic on a lot unless local rules allow smaller sizes.
- Verify local jurisdiction rules because county or city regulations can override typical acre guidance.
Leach Field Does Most Treatment
- Most treatment in a septic system happens in the leach field as wastewater interacts with living soil biomes.
- Soil filtration and biological activity provide the bulk of wastewater purification before groundwater return.
Do A PERC Test Pre-Purchase
- Get a PERC (percolation) test before buying if your plan depends on a conventional septic system.
- Use the test result to estimate whether conventional septic or an engineered system will be necessary and budget accordingly.
