Surely the many miles of underground pipes are a breeding ground for microbes, right?

As everyone else wrote, chlorine.

But.

Chlorine’s concentration (and it’s effectiveness) reduces as it travels along the pipes.

So. If you imagine a city where the water treatment plant is in the center and there’s a series of pipes branching out to all the buildings; the chlorine concentration in the water needs to be sufficient enough to reach the farthest building. This means that the buildings closest to the treatment plant has the highest level of chlorine, while the farthest one has the lowest level of chlorine.

Remember that bacteria need food just like we do. Water is a terrible medium for bacterial growth. There’s nothing to eat ! And there aren’t many bacteria to start with because municipal water is filtered and chlorinated. Also , you can handle plenty of bacteria in your water. Your stomach destroys most bacteria and even if it doesn’t the bacteria you swallow just move along your digestive tract. Sure they might start to reproduce but the digestive tract isn’t exactly home sweet home. If they survive the stomach acid and the digestive juices of the small intestine, they then end up in the colon which is already packed with bacteria. Uh oh!

I work for a water treatment company in the UK and we have ditched chlorine a few years back in favour of charcoal and ultraviolet light treatment as these are less harmful and cheaper to use and highly efficient. I can only speak for the region I work in as I’m sure some places still use chlorine. We start by removing any solid matter from the water course via filtration and once the solids are removed we then focus on killing off any harmful bacteria and pathogens with charcoal and then through ultraviolet treatment. This is then pumped to town reservoirs for people to use.
