My grandfather had 6 kids and his house had 3 additions that he did himself to make room for all of them. It's sound, but is missing niceties like good insulation, you can feel the wind blow through the bedroom. My mother tells stories of roller skating in the dining room before they put down the final floor. There is a boarded up coal chute and a dirty little room in the basement the used to have coal in it. After he died, his kids put in everything it needed to be habitable for my grandmother (new electrical, new roof, a bathtub). I can't imagine 8 people with 1 bathroom and no tub. After she died, it went to my mother and her sisters (Irish tradition, the boys got the business) and they are selling it to a cousin rent-to-own so it stays in the family. But the only other people that would buy it would knock it down and built 4 condos.
I don't mind the outdoor watering ban because I like to have water to drink and bath and for my fish. I don't care if FA can't run its nuclear plant, but if our lake dries up, the pipes will be dry or we will have to pay TN to tap the river up there.
Here is okay to water your lawn with creek water (which makes no sense to me), and its okay to use waste water. So if you fill the bathtub while you shower, you can drain it into the garden. I often dump my fish buckets on my flowers. Rainwater is okay, too. You can put barrels under the downspouts to catch it. In practice, this means companies and farms put pumps in the creeks and lakes and rivers to water their landscaping and crops, Florida complains about low water levels, the Army corps or Engineers releases more lake water and homeowners get tighter restrictions and higher water bills.
People here were just ignoring the non-watering notices or paying the fines, so they kept raising them. During the worst part of the drought, neighbors would tattle on you and dead lawns and dirty cars were a source of pride.
Wisconsin only has "severe" drought. We have "exceptional drought". We are lucky to still be allowed pools. If your restrictions are that strict without the kind of long-term super-drought we've had here, you should really wonder if your water supply is adequate. http://droughtmonitor.unl.edu/
Global warming or not, long droughts are something we should prepare for and water conservation is a no-brainer. I think the high water bills in Europe are the reason for the German nano tank trend.
