If you're building a new home in an area without municipal sewer access, then you will need a septic system on-site to provide wastewater disposal. Although it's easy to think that all septic systems are the same, there are several factors to consider for new installations. Choosing between an aerobic and anaerobic system will be one of the most crucial decisions you will make.
Anaerobic systems are the option familiar to most homeowners. These sealed systems break down waste using bacteria that do not require the presence of oxygen. Anaerobic systems use a passive design that does not require power. On the other hand, aerobic systems use oxygen-loving bacteria along with powered pumps to aerate the treatment tank.
Aerobic systems are drastically more expensive than their anaerobic counterparts, but the cost may be worthwhile. Below you will find three reasons that you may want to consider this wastewater treatment option for your new home.
1. Aerobic Systems Are More Compact
Although they require multiple tanks and various electrical components, aerobic systems require less yard space than conventional options. Since aerobic bacteria can treat water more efficiently than anaerobic bacteria, these systems can operate with smaller drain fields. If you have limited space or you'd prefer to use less land for your drain field, then an aerobic system may be the right option.
The compact nature of aerobic systems can also make them worthwhile in situations where placement is limited for other reasons. For example, if a larger anaerobic drain field would be too close to a shallow drinking water well, then a smaller aerobic drain field may offer better placement options.
2. Aerobic Systems Tolerate Poor Soil
In a traditional septic system, the drain field soil acts as a large, natural filtering mechanism. Aerobic septic systems rely on their drain fields in a similar way, but their higher efficiency means that they are more tolerant of poor soil. If a percolation test reveals that the ground on your property is poorly suited for an anaerobic system, then you will likely need an aerobic system instead.
3. Aerobic Systems Last Longer
Although they cost more upfront and tend to require more maintenance, aerobic systems also clog less and often last longer. Since they utilize smaller drain fields and rely on the drain fields less for treatment, you are less likely to face future repairs that require significant excavation. If you intend to keep your new home for long enough, you may be able to offset some of the initial costs.
Although anaerobic systems work for many applications, the long life and other advantages of an aerobic system may make one perfect for your situation.
