Wastewater from your home flows into the septic tank, which is a large tank typically made of concrete, steel or other materials such as plastic or fiberglass. Once there, any waste solids in the water settle out and are broken down by bacteria. As particles settle out, the water itself is able to flow out of the septic tank where it is distributed through a series of gravel-filled trenches known as leach fields where the water is absorbed into the ground. Any remaining waste materials are then broken down by microorganisms in the soil.
Some systems also separate greywater (water that comes from waste-free sources such as laundry, bathroom sinks and showers) from the “black” water that contains waste. While this water is not directly recycled as drinking water, it can be filtered and used as part of an irrigation system for non-food plants and lawns. This not only makes more efficient use of your household water but also reduces stress on the septic system as a whole.
Ideally, a septic system shouldn’t require too much maintenance to keep it functioning properly. With that said, there are a few things to keep in mind to ensure that your system doesn’t develop problems. Key points of septic system maintenance include:
In addition, it’s recommended that you have your septic tank checked every 1 to 3 years and have solids pumped out of the tank every 3 to 5 years to maintain optimal function. This may need to occur more often if you live in a cold climate, as bacteria may not break down waste as quickly when experiencing severe cold or prolonged winters.
Whether you suspect a problem with your septic system or just want to stay on top of septic tank maintenance, periodic inspections will help you avoid major problems down the road. The most basic inspections are simple visual inspections, where water is run through the sinks and the toilets are flushed to check for backups or other obvious problems. These are often performed by home inspectors but provide only a very limited amount of information about the condition of the system itself.
If you have a septic company do the inspection, you’ll likely get a much more in-depth job. These inspections check for signs of septic tank problems such as visual damage to the tank or depressions around the tank area that could indicate sagging in the tank walls. They will also check for odd odors, signs of leaks, the condition of liquids and sludge within the tank and even backflow once a portion of the tank is pumped. You should receive a report on the condition of the tank after one of these inspections, and most likely will have the results explained to you as well.
Provided that it is well maintained, a septic system can theoretically last for decades. More realistically, though, you can expect a septic tank (and the system it’s a part of) to last for between 15 to 25 years. The actual lifespan of any given septic tank depends on the material it’s made of, how well it was installed, the types of waste that are dumped into it and how often it is pumped or maintained. The more care you put into maintaining your septic system, the longer it’s likely to last.
Of course, once a septic tank starts reaching the end of its life it is important that you deal with it before hazardous conditions can form. If a tank is leaking or sagging, it needs to be collapsed or crushed and filled in around. In some cases, a new tank can actually be installed beside or on top of the old one after it has been properly taken care of.
