While many people think of their septic tank as their entire septic system, the septic drain field is perhaps even more important due to its function. By distributing purified effluent into the soil, the septic drain field handles the last stage in the wastewater treatment process. Without a drain field, or with a compromised one, the effluent has nowhere to go and can cause a host of issues when it backs up into the tank and into your home or business. Depending on the location, drain fields are also referred to as leach fields or leach drains.
A properly built septic drain field must conform to all local regulations, which can vary from area to area, so it’s important to inquire at your local office both for their specific requirements, as well as any needed permits and inspection rules and regulations you’ll need to abide by. In general, a septic drain field is usually set at least 10 feet from the home or business, 10 feet from any body of water, and 10 feet away from gardens or edible plants. The general rule of thumb for the trenches the septic drain field will occupy is one foot of pipe for every 10 gallons of tank capacity. The trenches should slope slightly downward, although a grade that is too steep should be avoided as it can result in the effluent pooling at the end of each pipe.
