In cold weather, the gases exiting from the stack contain water vapor that will form a frost layer that can get thick enough to close off the end of the stack. Gas from a septic tank has a bad odor, may cause serious illness, and in some situations, can be explosive. The main stack also acts as a vent for gases that collect in the septic tank. A 3- or 4-inch vertical pipe serves as the main stack to carry wastes, water vapor and gases from the house. Waste and vent pipes usually are the same pipe, with wastewater flowing downward and gases rising in the pipe. House plumbing includes waste and vent pipes, as well as plumbing fixtures. Then after the area has grassed over, you still can find the component parts of the septic system.įigure 1. Measure and record distances from the septic tank, septic tank cleanout and drainfield to aboveground features such as buildings, fence corners or large trees. When the sewage treatment system is installed, make a map of the installation. Separation distance between the septic system components and water sources (all distances in feet). Generally accepted safe distances are shown in Table 1. For example, keep the septic tank and soil absorption unit at least 100 feet away from any private well that is less than 100 feet deep, and at least 50 feet away from wells more than 100 feet deep. Whether you need a permit or not, concern for basic human health demands that the location of individual home sewage system components meets certain requirements. During the planning process and before construction, check with your local administrative office that deals with onsite wastewater systems for local requirements. City/county health departments or multi-county health districts require a permit before constructing a new home sewage treatment system or when repairing an existing system.

All individual sewage treatment systems must comply with requirements in North Dakota State Administrative Code section 62-03 1-03. The five parts of a sewage disposal system are: (1) the house plumbing, (2) the sewer line from house to septic tank, (3) the septic tank, (4) the septic tank outlet sewer pipe, and (5) the final soil treatment unit, which may be a soil absorption unit or lagoon. Bacteria feed on the wastes and the fraction that can’t be decomposed is “sludge.” Sludge accumulates in the bottom of the septic tank and must be removed periodically. The solid parts are heavier than water and sink to the bottom of the tank. Scum is lighter than water and floats to the surface in the septic tank.

Solids are composed of both scum and sludge. Gases are vented off through the house vent stack. The septic tank is a “bioreactor” where microorganisms break down organic matter in the wastewater to liquids, gases and solids. Solids are held in the septic tank and liquids are conveyed to the final soil treatment site. Home wastewater enters the septic tank, which separates solids from liquids.
