I don't think I will worry about first flush, as I'm counting on the sand filter. To be honest, I don't think I've seen above-ground cisterns - ferrocement or other material - used here locally or elsewhere in climates analogue to mine. The county wants all water useage to flow through a meter. What if you constructed a large ferro cement above ground cistern - because of the way they are made, I believe they can withstand heaving - or they may require a cement pad base. I live in an area that gets on average 60 inches of rain per year. They are very robust and with enough volume, probably wouldn't freeze, especially if you insulated it well.

Any thoughts or advice would be greatly appreciated!
