Everything you put down the drain or toilet has to go somewhere. Whether you're flushing the toilet, washing clothes, having a shower, or washing the dishes, we send a significant amount of water down the drains in our households each day.
The water and other materials that go down the pipes are processed and then released back into the environment. Sinks and toilets are not intended to be disposal systems for garbage or chemicals.
