"Cary spent a lot of his time on the phone and in person explaining possible causes for my septic issue and also gave me suggestions to resolve it. This allowed me to do my own labor after purchasing the necessary replacement pump from him. They were very busy at the time, but he was always available and extremely helpful."

Septic Tanks questions, answered by experts

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.

Septic tanks come in multiple shapes, sizes, and materials. However, they’re often round or rectangular in shape and made from concrete, fiberglass, or plastic. There’s a range of septic tank sizes, with the average model measuring 30 to 40 square feet and holding 1,000 to 1,500 gallons of waste.

Costs depend on tank accessibility, size, and local rates. Regular service serves as preventive care, averting costly emergency repairs or system replacements.

Septic tank locations are sometimes public record, although it depends on local laws and the property age. Older properties may not have the septic tank information on public record. To check, you can talk to local permitting agencies, such as your local health department, the local environmental department, or the county clerk.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.
