If you’re planning to install a septic system, you might be wondering: can a septic tank be 100 feet from a house? The answer is yes—many septic tanks are located well over 100 feet away, depending on local codes, property layout, and soil conditions. In fact, distance itself isn’t a problem as long as the plumbing is properly designed. What matters most is following local regulations, ensuring proper slope for drain lines, and maintaining safe distances from wells, property lines, and water sources. In this guide, we’ll explain septic tank placement rules, pros and cons of a 100-foot distance, and the tools that make installation easier.

- Plumbing Slope: Pipes must slope about 1/8–1/4 inch per foot to ensure waste flows properly.
- Soil and Drain Field: The drain field location often determines where the tank should sit.
- Access for Pumping: The further the tank, the more important risers and clear paths are for pump trucks.
