Ultra, only gonna comment about the water/waste water aspect; those actually affect public safety. Fire department and police have very little affect on anyone's true safety. Get a whole town sick from bad water, or a sewer discharge. I'm not saying fire department doesn't help people, but in the grand picture it is a Very small number per year.
If you live in/near even a medium sized town of 10k, they will probably have dozens of breaks per year, upgrades, ect; and the general public doesn't have any idea how expensive underground water/wastewater work really is. Sure directional drilling, pipe bursting, CIPP, and slip lining have helped keep the prices from climbing faster than they would, but trust me, it's climbed. Also, you Can defer some maintenance for a few years to a decade, but with that, a minor repair can/will turn into a major rebuild, and there isn't a cost savings.
Look at the Jackson Mississippi case. Something like 200 days out of a year they were unable to provide treated drinking water to significant parts of the rate payers. That's a Dang serious public safety problem, and yes, it was caused by 50 years of corruption, incompetence, poor planning, deferred maintenance, and bad decisions.
