A pluming ploblem?
Answers: It seem to be that you have a clogged drainage queue. Take a look in your crawlspace/basement for you septic pipe. There may be an access port on it. If you loosen this(be prepared for a LOT of fluid) you may be able to attain to the clog with a snake. Keep surrounded by mind, you clog could be located anywhere on the pipe after the drains for your toilet, kitchen sink and tub are located.
Black offers a valid suggestion. Somewhere within your plumbing should be a threaded cleanout plug. It may be outside the house, as many are, and usual access is next to a Crescent or open call a halt wrench, then the cleanout process.
While you're at it you should probably check and verbs out all the VENT pipes as economically.
From that point on be careful what go into your drainage system
