Septic Field Vent Pipe

Ventilation pipes are responsible for venting gases and air from the septic tank. The ventilation pipe can be raised to release odors. This allows for the structure to be blown by wind on a windy day.

Is A Septic Field Required To Have A Vent Pipe?

Your septic system, and any sewage system for that matter, must have a venting system. This allows gases to escape the system. It also prevents dangerous buildups or airlocks from forming. Three methods of pipe ventilation should be available for your septic system: Inlet & Outlet and Roof-Vent.

Increase the Vent Pipe’s Height

The ventilation pipe, as mentioned above, is responsible for venting the gases and air from the septic tank. The pipe’s height can be increased to allow the release of odors. This allows for the ventilation air to be blown over the structure by wind.

Septic Tank Overview

Septic tanks are usually made up of large concrete, steel or fiberglass containers that can hold around 1,000 gallons. They are typically buried underground close to a home or commercial building. The nearby structure has pipes and toilets that are connected to the tank. The waste from a bathroom is emitted through the pipes to the tank. It settles at its bottom and then decomposes. The water is then pumped to a local water treatment plant or drain field.

How is a Septic System Designed?

We have stated before that ventilation is essential for sewage systems to allow gasses to escape. We haven’t looked at what ventilation looks like in a typical septic tank.

Ventilation of the Outlet and Inlet Pipes

Your septic system’s first ventilation is via the inlet and outlet pipes. The inlet pipe allows for waste to flow into your septic tank, while the outlet pipe allows it flow to the drainage field. When these pipes are clear, they should allow gasses to flow into the drainage field.

Your Roof Vent Pipe

They were actually vents from the bathroom fan. But it turns out that those pipes venting from your roof are meant to draw septic system gases and odors away from your home.

The Purpose of Septic Vents

These are two different things. The vent stack in the house prevents sewer gas from leaking back into the traps and provides pressure relief. The yard vent is designed to manage gas from the septic tank. It is not clear if this is required by your local code or as part or your specific design. Some people believe it prolongs the life expectancy of the tank and leaching fields. I’ve lived in cities where people added tanks vents to their homes, while others did not. There is no rhyme or reason.

Septic Field Lines

Septic tanks are an efficient on-site wastewater treatment system that can be used to remove waste from buildings not connected to the municipal sewer line. Gravel and rocks is a traditional method of installing wastewater sewer effluent pipes. It provides overburden support for ground around the system.

Septic

The home plumbing system includes the leach field sewer lines that are used for septic systems. These include the line from the house to septic tanks, the outlet pipes, and the treatment field. The effluent outlet pipe or leach field should be placed so that they don’t affect the water supply.

Pipes

Most pipes used in gravel-filled sewer tunnels are made from a plastic material such as HDPE. These pipes are available in smooth-walled, rigid or corrugated forms. They can also be bent to fit within property boundaries.

Charcoal Vent Filter

Attaching a charcoal vent filter to the top end of an existing ventilation pipe is an inexpensive solution. The charcoal filter not only allows gases and air to pass through, but also removes the unpleasant odor. This vent can be attached to the business’s roof ventilation pipe. It pulls odors up and out from the home, and does so above the roofline.
