I'm surprised, to say the least, that so many people think water should be free. I've been to many countries where there is no running water, while our friends, who live in Spain, do have running water, but it's not safe to drink.
We take it for granted that whenever we turn on the tap, fresh, clean, unlimited water comes out - and yet millions of people still buy bottled water, because they think it's somehow better than tap water.
Your water bill pays for the infrastructure to collect that water and deliver it to your tap. It pays to have that water cleaned and treated, so that it's safe to drink. It pays for the infrastructure to take your waste away from your house and treat that, too (which is why your bills are lower if you have a septic tank).
While I agree that the water companies are often doing a bad job controlling leaks and haven't invested enough in new reservoirs, we should all be grateful that our water is actually very cheap. If you want free water, then set up some water butts. I use my collected rainwater for watering the garden, washing the car, etc, but I certainly wouldn't drink it or brew with it!
