A septic tank is underground and helps waste water from homes decompose. The water will exit the septic tank in the drain field, where there is further decomposition.

In fact the waste water merely transits the septic tank on its way to the drain field where it undergoes an aerobic process in the earth, being cleaned and turned back into water.

The septic tank holds our solid waste, while it undergoes an anaerobic (airless) process, where it is turned into methane, carbon dioxide and various other gases. The solids start off as 70% water, after process they are very much reduced and are more or less compost, that is collected when the tank is full (in fact less than half full) and spread on fields as compost, or taken to a sewage plant for further process before being spread in fields as compost.

What happens after the water goes down the drain from the toilet?

That depends on how your sewage is treated, it could go into a septic tank in your garden or it could go into the public sewer and on to a sewage treatment works (sewage farm). In both cases raw sewage is prevented from discharge directly into the environment and the sewage is retained until natural processes have converted it into water that is safe to discharge.
