"We hired Rocking MT to replace the holding tank on our septic system. Stephen did an excellent job. He is a very skilled contractor who worked through several obstacles while communicating with us all along the way. The quality of his work was outstanding. He left the job site very clean. I would contract with him again in a heartbeat. His quote was reasonable and the final price was very close to what he quoted."

Septic Tanks questions, answered by experts

The price you’ll pay for service from a septic tank company will depend on the specific service you need. Here are some common services, along with average pricing:

  • Anaerobic septic system installation: $3,000–$8,000

  • Aerobic septic system installation: $10,000–$20,000

  • Septic tank pumping: $250–$550

  • Percolation test: $700–$2,000

  • Leach field installation: $2,000–$10,000

These numbers vary based on your septic system size, property layout, and more, so the best way to get an accurate estimate is to contact a septic tank professional for a custom quote.

Regular checks of pressure tanks, testing water quality, and cleaning intake screens.

The dimensions of a 500-gallon concrete septic tank can vary from manufacturer to manufacturer, but the tank is large enough to handle the wastewater of a small home with up to one bedroom. Keep in mind that some states have a minimum septic tank size, and this often starts at 750 gallons. A 500-gallon septic tank may be too small to meet local regulations.

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.

Your septic tank naturally contains the beneficial bacteria it needs to function, so you typically don't need to add more. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three overripe tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many experts consider them unnecessary and potentially harmful. The most effective way to maintain a healthy bacteria population is to avoid using chemical drain cleaners, which can kill the good bacteria in your system.
