The most common types of septic tanks are aerobic, anaerobic, and hybrid. Aerobic systems use oxygen to break down waste while anaerobic systems don't. Hybrid systems combine both aerobic and anaerobic processes. Aerobic systems generally require more maintenance than other systems because they need to be pumped regularly to keep the water from becoming stagnant. Anaerobic systems are less expensive but can become clogged if not properly maintained.
