SepDig, a Septic Excavation Depth Calculator

Field notes

SepDig models septic layout from field measurements, including the sewer invert at the foundation, run length, slope, tank dimensions, and a rod reading taken at the excavation bottom. Its displayed example uses a 40-foot run at 2% slope, a 1,000-gallon concrete tank, and a calculated pipe fall of 9 5/8 inches. The interface also exposes job details, notes, benchmarks, drops, turns, cleanouts, and saved plans, indicating a workflow broader than a single one-off calculation.
