How much does it cost to replace a drain field?

Extending the life of septic drain fields and avoiding the huge expense of replacing a drain field are the reasons we developed Drain Field Cleaner. So, just how much does it cost to replace a septic drain field (aka, leach field)?

The Cost to Replace a Septic Drain Field

The cost to replace a septic drain field can vary widely based on several factors, including the size and type of the system, soil conditions, local regulations, your geographic location, and any additional requirements like site preparation or landscaping. Here are some estimates and guidelines for the total cost:

  1. Basic, Average Cost: On average, in the United States, you might expect to pay anywhere from $2,500 to $10,000 to replace a drain field. However, this can vary.
  2. Size and Type of System Are Important:
    • Conventional Anaerobic System: This is generally the most affordable option, with costs ranging from $2,500 to $5,000.
    • Sand Mound System: Used when soil conditions aren’t ideal, mound systems can cost between $5,000 and $20,000.
    • Drip Distribution System: This system, which uses a higher dose of effluent, can run between $5,000 and $12,000.
    • Aerobic Treatment Units: This type of system, which uses oxygen to break down waste, can cost anywhere from $10,000 to $25,000.
  3. Labor: This is a significant portion of the total cost. Labor rates can vary based on the region and the complexity of the job.
  4. Permits and Testing: Before replacing a drain field, you’ll likely need permits, which can add to the cost. Soil testing may also be required to determine the best type of system for your property. Combined, these can add several hundred dollars to the overall price.
  5. Additional Costs: These might include tree or stump removal, landscaping, fence removal for access, or any other site work required before the new field can be installed.
  6. Geographic Location: If you live in an area with a high cost of living or where septic services are in high demand, you might pay more.
  7. Complexity of the Job: If there are challenges like difficult soil conditions, a need for advanced systems due to local regulations, or hard-to-access locations, costs can increase.

Given the variability, it’s essential to get multiple quotes from reputable septic system professionals in your area to get an accurate estimate. Remember, while cost is a factor, the quality and longevity of the work are crucial if you do end up having to replace your drain field, make sure to choose a reputable professional. It’s often better to pay a bit more upfront than face issues down the road due to subpar work.

Try Drain Field Cleaner

Of course, we DID develop a product specific for cleaning drain fields and extending their lives. Thousands of customers have saved thousands of dollars by using Accelerator by Dr. Pooper Drain Field Cleaner instead of replacing their clogged or slowly draining drain fields.

While Drain Field Cleaner can’t fix every problem — it won’t clear roots, for example — it does clear clogs, sludge, and scum that block drain fields and keeps them from working properly. So, give it a try. If it doesn’t work, our money-back guarantee is standing by.

    According to a book I just got, The Septic System Owner’s Guide, septic system additives, especially enzymes, break down scum and sludge into small particles which are flushed out into the drainfield increasing the possibility premature drainfield failure. How is yours different? I just ordered the drainfield cleaner from Amazon and now I’m nervous!

      Thank you for your business. We appreciate it. This is a common misunderstanding that gets perpetuated by conflicting interests in the septic industry. The bacteria eat the solids and the resulting byproducts of their digestions are mostly gases (carbon dioxide, ethane, methane, H2S), water, and some biosolids — which are all safely absorbed into the air and/or soil. Accelerator by Dr. Pooper®️ simply speeds up the process — and continues in the drain field, where the solids are still eaten by the bacteria. The main difference is that Accelerator by Dr. Pooper®️ inhibits the production of H2S (a dangerous gas). The real concerns around drain fields are inorganic solids (such as salts and minerals in the water and/or from water softeners) and the type of soil (clay has a higher failure rate due to it’s low absorption rate). Where organic solids are concerned, the biggest issue is a broken or disconnected baffle on the exit side of the tank(s) that allows a high volume of solids to flow into the drain field that the system and bacteria simply cannot keep up with. Sorry for the long answer but we wanted to be reasonably thorough. Thanks again!
