Hard water

That is an excellent point and it is something that we do on a small scale right now. It doesn't help during these long stretches when there is no rain water to collect. I have plans to do something on a larger scale for collecting rain water but it is a project that hasn't yet floated to the top of my list. It is part of a project that I have in mind for creating a small scale pumped hydro system on our property to compliment our solar and should further help us reduce our use of the dirty electricity that we get from CFE.
