When you flush the toilet, where does the waste go? If you live in the country — somewhere without a public sewer connection — your waste will go into a septic tank. When everything is going as it should, the waste will slowly break down in the tank, and the liquid will flow out. But if everything is not going as it should, your septic tank needs service. It might just need to be pumped, or it may need to be patched or replaced. You can learn more about these services, and about septic service in general, on this website.
