The answer to 'types of septic tank' is that there are several common types of septic tanks used in residential and small commercial settings. The most common types are concrete, plastic, and fiberglass septic tanks. Concrete septic tanks are the traditional and most widely used option, as they are durable and long-lasting. Plastic and fiberglass tanks are becoming more popular due to their lightweight construction and ease of installation.
Septic tanks come in a range of sizes, typically between 1,000 and 2,500 gallons, depending on the size of the home and number of bedrooms. The size of the tank is an important consideration, as it needs to be large enough to handle the household's wastewater flow. Homeowners should consult with a professional plumber or septic system installer to determine the appropriate tank size for their property.
