Off-Grid Septic System: My Secret to No More Sewer Bills!

What happens here

Begin excavating the hole for the septic tank and the trenches for the drain field. Use a Kubota mini-excavator to dig the main hole for the industrial tote, ensuring it is deep enough for the tank to be fully buried with enough space for pipe connections. Subsequently, dig trenches extending from the tank for the French drains. Maintain a precise pitch of 1/8 inch per foot for the drainage pipes to ensure proper flow and prevent solids from accumulating. It's crucial to take extreme caution when operating heavy machinery, especially near obstacles like buildings, trees, and other equipment, keeping the throttle low and movements slow and deliberate.

Goal: Dig the main pit for the septic tank and trenches for the drain field with proper pitch.
