Dervish said It's terrifyingly easy to contaminate a water reservoir. For example, if someone were to pour just 2 liters of oil into a 390,000 liter reservoir, the entire supply of water is pretty much undrinkable and capable of making people sick. I would not want the nightmare of having to try to replace and treat that much water when it's an essential service and trying to clean out the entire reservoir from any lingering contaminants. Plus, if that happened, the operator would probably be looking and crushing fines and jail time for not securing the water supply.
So really, appreciate the efforts the guys in your municipality go through to make sure your water is clean and safe to drink as well as keeping up with demand. It's a very tricky line of work.
Really? 0.000005% oil content? Drink a litre, and you don't even get a millilitre of oil.
