I know NYC doesn't treat their water at all, but LA doesn't either? My city runs on surface water, so we have treatment and then pump to storage tanks. You would have to be out for quite a while to run the city out of water, though - the tanks are large. | ||||||||||||||||||||||||||||||||||||||

LA definitely treats the water. Both the surface water before consumption (I'd be surprised if any city doesn't do this) and the wastewater, for reclamation for nonportable use like irrigation, and for recycling back into the general clean water supply. The aqueduct water is specifically purified by the Los Angeles Aqueduct Filtration Plant. That plant is gravity fed, but it doesn't operate without power. LA just has the advantage of having mountains in the city, so it's cheaper building more elevated water storage so the capacity lasts longer during power interruptions (which are also not as common or extended as they are in the east). They will still eventually run out if they're not replenished by powered pumps. | ||||||||||||||||||||||||||||||||||||||

Where did you get that idea about NYC water being untreated? NYC treats its water. Chlorine is added if and when needed. Testing stations exist to evaluate water quality all around the boroughs, etc. You can't have a city of millions of people and have the water be potable from the tap without testing and treatment | ||||||||||||||||||||||||||||||||||||||

I know NYC doesn't treat their water at all… EDIT: I'm a dork an grabbed the wrong URL. Changed URL to a PDF for lack of better. A major metro doesn’t treat its tap water? Where on earth did you get that crazy idea? <old URL deleted> https://www.nyc.gov/assets/dep/downloads/pdf/water/drinking-... I'll save some digging: "Even without filtration, the water is carefully treated to reduce the risk of harmful microorganisms." | ||||||||||||||||||||||||||||||||||||||
