Having spent 11 years living with a septic system as my number one source of home anxiety, I find living on a sewer system, once again, to be amazing.
While I was living in rural Marin County, I got a Mill Valley Waste processing plant tour, with my daughter's 4th or 5th grade elementary school class. While foul-smelling, it was an amazing tour explaining the system.
I have ever since been sensitive to what I flush, and employ tub stoppers at almost every drain.
This video, by Practical Engineering, is just as good and doesn't stink.
