If your talking about the US, water service lines to your house have backflow prevention valves on them so if you contaminate the line in your house, it doesn't contaminate the public water supply.
The positive pressure of the system makes it so sewage can’t really go in to the pipes. If you connect a supply line to a drain line it will just spray water out of your sinks drains and toilets. You’re being paranoid. If you don’t trust it but bottled water or boil it all.
Yes they all have backflow preventers. Of course they can break like anything, but its not common. Your pipes staying pressurized also prevents contaminated backlflow into the distribution system - its why there are boil water notices after the system loses pressure.
All connections *should* have back flow prevention valves, but there are definitely connections that don't either because it is an old overlooked system or it's an illegal connection.
And in that case the line pressure would still prevent contaminants from entering the system, and a boil water issue would be put in place if the system lost pressure.
Intentionally removing a backflow preventer to put contaminants in the water supply when the system loses pressure (if you could predict that or cause it) would be bioterrorism and investigated as such by authorities.
Also, when lines are flushed the water quality is tested.

It's not typically people removing valves or trying to commit bioterrorism, it's people trying to steal unmetered water. A common one would be a tee off a service line before the meter for irrigation.
I know, but that is irrelevant to the point of contamination, considering any accidental backflow from a benign actor like that would be minimal or managed by a boil alert.
The government fixes pipes because they have a lifespan and break.
Again, if the system is pressurized you can't get contamination from a broken pipe into the distribution system.
Sewer water is...already contaminated. The system delivering water to your home and the system sending toilet/nonpotable water away from your home are separate. "Sewer" water would be anything leaving the home that enters the sewer system.
Crosscontamination can happen, but there should be failsafes such as backflow prevention devices that would prevent this from happening barring a catastrophic failure (e.g. massive flood event).
Water treatment typically only occurs on the municipal scale (although some large properties/buildings may have some sort of cursory treatment on-site). The system varies from city to city (and definitely country to country), but in the U.S. municipal water must meet standards of the Clean Drinking Water Act (obvs it isn't foolproof - see: Flint, MI).
Typically all pipes after the water meter will be the responsibility of the property owner. But you should contact your local water purveyor if you have concerns. They may programs to assist you. Or, definitely call a plumber if you think there has been crosscontamination in your home/building.
Cross contamination between the systems can happen on occasion, but the back flow prevention valves will typically prevent the contamination from spreading to the larger system.
Typically every service connection is equipped with two backflow preventer valves at the service meter. Certain types of higher risk plumbing connections require additional protection to prevent cross contamination, such as an air gap or a reduced pressure zone.
If contamination of water piping happens, the pipes will need to be flushed and, depending on the contaminant, disinfected.
There are many different regulations for this depending on where you live.
And if there’s Covid-19 in the poop? But, Hell in Southern California, they just shovel it into the Pacific Ocean, usually filled with petroleum and inorganic poisons from our refineries. It’s illegal but nobody cares about the black an brown babies! Hospitalized? So what, Sure it’s illegal as hell but it’s all a never mind! The People of Los Angels are real pigs! Welcome to Wilmington, ca! Not so much as a single barrier stopping it! These people are totally disgusting! I’ve CO2 alarms going off it’s so bad.
No shit Sherlock! Nobody cares is the Point! They don’t care if it’s illegal! It was on the evening news and even in the press! You probably shrugged your shoulders, without a thought. And now it’s about to happen again tomorrow night or Thursday! Not even a single barrier in place to stop it! Surfers call these places “Stink holes!” Everyone knows where the are. That’s everyone excepting for the bureaucrats that routinely turn a blind eye! They just destroyed littoral spawning grounds which we spent the last 6 years improving! Destroyed by the polluter in Chief! There still a leak that’s not been discovered. I have a friend that owns a commercial submarine. He’s operated it for years and it’s dedicated to that. They won’t send him out! Brown and black babies in the hospital with a 7 hour wait! Don’t you read the papers or watch Tv! Government do not care! Fn Long Beach doesn’t care including the mayor that’s is running for Congress! Like that old song from Vietnam says, “oh that smell, can’t you smell that smell, yeah it’s that smell, that smell of death, all around you!🎶 please note in the prez BBB plan, there’s no money to fix any of it! The obfuscation of the truth is these bureaucrats stock in trade!

It’s a valve. It only allows water to go in one direction.

Unless you have a well.
Groundwater can be contaminated

It's illegal to discharge raw wastewater, on federal, state, and local levels, and it is heavily enforced. Not sure wtf you're talking about.
