Bucket

Hi Paula,
It is more about saving water because of the drought.
I am guessing a conservative shower takes about 30 gallons and a longer shower might take 60 gallons or more.
I actually plugged the drain once and took a shower to see how much I used. It was about 1/2 a bathtub which I am guessing is around 30 gallons. I was in conservation mode, and I think my showers are normally longer and much more wasteful than that. In comparison 2-3 gallon savings a shower seems insignificant, but multiply it by how many people in the household use it, and then by the shower days in a year. It adds up to significant water savings. At least it seems like it to me.
I mostly do it because it is not a huge hassle and it makes me feel better. I would much rather have a grey water system in our house, but that will be much further down the line for us due to the effort of installation, permitting, and cost involved.
