If you live off the sewer line, you have to come up with other ways to dispose of all your wastewater and the products that it contains. You can recycle some of it, like greywater, from your sinks, tubs, and washing machine, but that can take a lot of work, and you have to install a system that would let that actually work. And that doesn't accommodate the blackwater from your toilets. The most common and sensible solution is to use a septic tank. A septic tank isn't just a tank; it is a system with several parts that all have to work in order for the whole system to work.
The septic system consists of a tank that is buried on your property near your house. Putting it underground keeps the tank safe from anything that could damage it. It also lets gravity help the system work. When the wastewater flows down your drain, gravity helps it run into your septic tank. The tank is generally made up of two chambers connected with baffles. The first chamber is where the wastewater collects in the beginning. That tank has bacteria that will eat the solids in the water, breaking them down. Their waste and the digested solids end up as sludge in the bottom of the tank, while grease and oils end up as scum on the top of the tank. The baffles are located in the middle of the tank, so only fluids flow into the next chamber. Eventually, the water runs out from the second chamber and flows into the leach field, the ground around the tank, which lets the water finish filtering and slowly absorb into the groundwater.
Septic Tank Issues
Like any other system, your septic system can have issues and break down. One of the most common is that the tank gets full, and you have to get it pumped. One sign that you might need to have your tank pumped is if you try to flush your toilet or run any water down the drain and it won't go anywhere or backs up into the drain. You might also notice puddling around your septic tank or a foul odor.
If you live in the country or somewhere not near the municipal sewer, you need to have a way to get rid of your wastewater. That generally means having a septic system on your property.
