Our water pressure is very low, so we're not doing a lot there. We don't use that much water anyway, most of the time, so it's not a big deal.
I also have 50 gallons of runoff water set side for toilet flushing and washing if necessary - with chlorine tablets added to it.
So, for right now, we're doing okay. The neighborhood was relatively lightly touched. Lots of limbs down, about six trees per block down, but only a few of those trees seriously damaged property. (almost one per street for being a blockade)
