Get matched with top septic tank pros in Wallace, SC

When your septic system is failing, you’ll probably smell it. Common signs of a septic system failure include sewage odors in the home or around the yard, flooding in the yard above the septic tank or in the leach field, and wastewater or even raw sewage backing up into your home’s drains.

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.

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.
