What Is the Process for Septic Tank Installation in Duncanville?

The process for installing a septic tank on your Duncanville property will typically go as follows:

  1. Get a percolation test. Perc tests will tell you more about your soil type, and specifically, how well it drains. This is really important in Duncanville, where we have soil with high clay content. That can make it difficult for the effluent, or discharged water, to drain away from your leach field. Perc tests cost between $200 and $800. 
  2. Decide on location and septic system design. Our experts can help you with this process. They will be able to advise you on the best options for your property size based on household needs, soil type, and budget. 
  3. Get your permits. Duncanville requires that all households within the city limits get a permit before installing a septic tank on their property. You can get these permits through the city’s Permit & Inspection Services Department. They’ll cost you a couple of hundred dollars, which will cover the cost of the inspection, too. 
  4. Our excavator will then dig out the tank pit and leach field trenches. This process will vary depending on the kind of system you choose and the size of your tank. For an aerobic tank system, the most common type for new installations in Duncanville, the pit can be considerably smaller. The length of the leach field trenches will vary, too, depending on the location requirements. For example, Texas state law mandates that the leach field has to be at least 100 feet away from a well and at least 20 feet away from your home. 
  5. Install the tank and drain lines. Tanks can be concrete, fiberglass, or plastic, depending on your budget and system needs. Drain lines can be made from a variety of materials. Some are made from recycled materials, making them very eco-friendly. 
  6. Wait for your inspection. Before our experts can fill in the pit and trenches, you’ll need an inspection from a city inspector. They will ensure the system meets the minimum requirements under Texas state building codes. Once satisfied, they’ll sign off on the paperwork and our professional will start filling everything in. 
  7. Backfill the pits and create the final grade. Once the inspection is complete, our contractor can fill in the pit and trenches and fill your tank with water to get it working. They’ll also level the ground above the system, keeping access pipes visible for inspections and pumping. We’ll run some tests and make sure you understand how to maintain your system going forward. 

How Does Permitting Work for Installing Septic Tanks in Duncanville?

Texas requires you to get a permit for your septic tank in most situations. There are some specific circumstances where you can install a septic system without a permit. You can read about those exceptions on the Texas Commission on Environmental Quality website. Whether you get a permit or not, though, you’ll need to meet the minimum requirements as laid out by the Texas Administrative Code.

According to the Duncanville municipal code, though, any household within city limits needs a permit before installing a septic system on their property. You can get a permit from the Duncanville Permit & Inspection Services Department. Getting your permit will only take a few days and a city inspector will have to sign off on the installation before our contractor fills in the tank pit.

How Much Does Septic Tank Installation Usually Cost in Duncanville?

The cost of septic tank installation in Duncanville will vary widely, with homeowners paying anywhere from $1,500 to nearly $10,000. On average, though, you can expect to pay around $5,500 for the installation of a new tank. These three factors will determine your final bill:

Cost Factor: The Type and Size of the Tank

There are a lot of different septic tank options. Concrete tanks are the most durable, but often the most expensive. Fiberglass is stronger than a plastic tank, but the plastic tank will be the most affordable. You’ll want to work with our plumber to determine the best tank for your location, your budget, and the needs of your household. The tank will be the biggest chunk of your parts and materials expenses, but don’t forget to factor in the cost of your drain lines, too.

Because of the type of soil we have here in Duncanville, there is a good chance you’ll need an aerobic septic system on your property. These are the most expensive septic systems, so expect to be at the higher end of the budget for installation. If you are one of the lucky households to have sandy or loamy soil in North Texas, then you can opt for a less expensive conventional system.

Cost Factor: Permitting and Testing Costs

Before installing your septic tank, you’ll need to get your soil tested and obtain the right permits from the City of Duncanville. Permits cost around $300 and your testing will vary but typically fall under $500. Some testing requires you to dig out a pit on your property, so we’ll need to bring in a backhoe to do this work for you. You should budget between $1,000 and $2,000 for this part of the process. 

Cost Factor: Expected Labor Costs

Some septic tank installations are easier than others. It depends on the type of system you are installing as well as your land type. Our septic tank installer will take this into account when providing you with an estimate on the costs. They’ll also look at additional labor expenses your project might require, such as land clearing. On average, installing a septic tank system takes about a week and there will be multiple people working on your site at once. That means, labor expenses can be a significant portion of your final bill. If you want to reduce those expenses, there may be things you are able to do yourself.

What Type of Septic Tank Is Best For Residents in Duncanville?

Your soil type is the biggest factor when determining what type of septic tank is best for your Duncanville property. Our region lies along an area known for its Blackland Prairie soil, which is very fertile but full of clay. Duncanville’s main soil types are Houston black clay, Trinity clay, and Bell clay.

So what does that mean for your septic tank? Unfortunately, soils that are heavy in clay content aren’t great for traditional septic tanks. That’s because, for a traditional septic tank to work, you need a leach field that allows for drainage of the water coming out of the system. This cleans the water coming from your tank before it reenters the groundwater system. Clay soils don’t allow that to happen, so you end up with hazardous water-logged areas around the leach field. 

There are solutions, though. If your land has soil high in clay content, then you’ll want to consider an aerobic system. These systems are essentially miniature sewer treatment plants buried in your yard. They expel water that’s much cleaner than you’ll get from other systems. You can then drain that water off without it becoming a hazard, or you can even use it to water your yard. 

Aerobic septic systems take up less space, work with any soil type, and will last for decades. They do require more maintenance than other systems, though. Our installation team will provide you with details on the best practices for looking after your septic tank. 

How Often Do Homeowners in Duncanville Need to Have Their Septic Tank Inspected?

The Environmental Protection Agency (EPA) recommends having your septic tank inspected every 3 years and pumped every 3-5 years. This timeline will vary based on your tank size and household output, but it’s a good rule of thumb. However, you should consider contacting us for an inspection sooner if you are experiencing any problems such as: 

  • Slow drains or toilets that are slow to flush 
  • Having to flush your toilet multiple times to empty it
  • The water-logged ground around your leach field
  • Depressions in the ground over the area where your tank sits
  • Unusual increase in bad odors around your tank

These are all signs of damage to your septic tank or drain pipes. Because these systems are underground, it’s best to talk to our septic tank technicians who can inspect the system with cameras and other specialized equipment. They’ll be able to pinpoint the leaks and give you options for repair or replacement.

When we come for an inspection, make sure to keep detailed records of our findings. You’ll want to record the date of our visit along with the sludge and scum levels. These levels indicate how full your tank is and will help you and our experts determine whether to pump your tank. The EPA recommends having your tank pumped if: 

  • The scum layer is within 6 inches of the outlet
  • The sludge layer is within 12 inches of the outlet 

After a few visits, you’ll have a better idea of how often to pump your septic tank. The average household size in Duncanville is just under three people, and on average, households of that size can safely pump their tanks every 3 to 5 years. If you host a lot of events or have additional family members move in, though, you’ll want to get your tank pumped more often.
