Should You Install a Septic Tank on Your Own?
When it comes to septic tank installation, it may be tempting to use a DIY approach in an effort to save money, but is it really a good idea? Even for experienced DIY’ers who have done things such as building a deck or replacing a sink, a septic installation is much more complex. Can you install a septic tank yourself? Technically, you may be able to, but there are many reasons to avoid trying the DIY septic system approach, including legal complications, the risks that come with installation, and the high chances of problems resulting from the failure of a DIY septic system.
Let’s look at the key things to consider about septic installation:
The Reality of DIY Septic Tank Installation
When pondering, “Can I install a septic tank myself?”, the answer isn't as simple as yes or no. Depending on where you plan to build, there are some states that allow homeowners the option of installing their own septic systems. Others do not. This is true at the local, city, and county levels as well. Failure to follow the law or codes in your area could put you in serious legal trouble, including fines or worse, as well as the expense of having your DIY septic installation removed professionally. If that happens and you still want a septic system, you will have the added cost of paying a professional to install a new one.
Even if your area allows for a DIY septic installation, there are other things to consider, such as materials, equipment needed, and the knowledge required for a successful installation. It’s more complicated than replacing a toilet, requiring an understanding of the precise calculations, ground preparation, environmental impact, and the risks of a system failure leading to a costly situation that may also have legal ramifications.
Costs of Materials and Equipment for DIY Septic Installation
A good starting point when considering a DIY septic system is the cost of materials and equipment needed for even the most basic septic installation. Here is a short list of what you’ll need to consider:
- Septic Tank: $600 - $2,000, depending on the size and type.
- Piping: $200 - $600 for quality, durable pipes.
- Gravel and Sand: $500 - $1,000 for the required fill material. This varies depending on the size of your system.
- Heavy Equipment Rental (e.g., Excavator): $300 - $600 per day. Most states also require someone that is specifically trained and certified on the heavy equipment.
Consider the cost of transporting these components, including the significant difficulty of transporting the dirt and heavy equipment. On top of these basic large items, there is always a variety of smaller items, such as couplers, connections, etc.
Risks of DIY Septic System Installation
Septic system installations are a complex system and an important component of your home or building. The risks tied to self-installed septic systems can outweigh the upfront savings. Even minor errors can cause problems such as sewage backups, burst pipes, and other malfunctions that disrupt the system functionality. This will lead to more frequent maintenance, repairs, and pumping, even if your system functions to some extent.
There is no nice way to say it: a septic system that handles human bodily waste is considered a biohazard. An improperly installed system can lead to contamination of local water sources, posing health risks to everyone in your area and a very expensive clean-up (That might also come with legal ramifications.).
Permitting and Legal Aspects
With any DIY project, you want to be aware of your local and state permit requirements, laws, and codes before you start. If you’re considering a DIY septic system installation, do your research before you try it yourself. If your area does allow for DIY septic systems, permits can range from $100-$1,500, and you may need multiple permits, inspections, and other processes depending on local regulations. You will need additional final inspections to ensure the completed system meets environmental and health regulations.
Failure to meet these requirements can result in fines, additional legal consequences, and/or forced removal of the system at your expense.
Is DIY Septic Installation Really Cheaper?
A lot of people assume that a DIY septic installation would be cheaper than paying a professional since you’re basically supplying your own free labor. In reality, when you add the cost of materials and equipment, the risks caused by mistakes made during the installation process, unexpected expenses, and the fallout of an improper installation, the savings aren’t as great as they might appear. Hiring a professional company to handle your septic installation may bring sticker shock at the initial quote, but the benefits are immeasurable. A professional company understands the laws and regulations have the trained staff such as equipment operators and their own equipment. Still, they also come with warranties and guarantees on their work that can protect you from a catastrophic system failure, legal issues, and expensive future repairs.
