"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

Baking soda does very little to nothing for a septic tank, but it can help unclog a drain or clean out a garbage disposal. Rotten tomatoes and yeast are the best ways to increase the bacteria in your septic tank naturally. You can add these to your system once every three months.

Options include submersible, jet, and centrifugal pumps. Choose based on water needs and well depth.

The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.

A septic system's lifespan typically ranges from 15 to 40 years, with a common average of 20 to 30 years. The longevity heavily depends on the tank's material, maintenance diligence, and usage habits. With proper care, lifespans can reach the upper end of this range.

Lifespan by Tank Material:

  • Concrete: 20 to 40 years

  • Plastic or Fiberglass: 30 to 40 years

  • Steel: 15 to 20 years

To maximize your system's lifespan, follow these maintenance best practices:

  • Regular Pumping and Inspections: Have the tank pumped every three to five years and schedule professional inspections regularly.

  • Mindful Usage: Only flush human waste and toilet paper. Avoid putting items like cat litter, paper towels, cigarette butts, fats, grease, oils, or coffee grounds down your drains.

  • Avoid Chemicals: Do not pour harsh chemicals into the system.

  • Water Conservation: Reduce the amount of wastewater your system has to process.

  • Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.
