Hi,
I am on LI in NY and do not have a homestead, but I did read articles here on things like water sterilization. Solar sterilizing has bene's but a sand filter lasts about 10 years when fully going it does a very impressive job assuming there is no chemical contamination here is a link to a CDC web page on solar sterilizing which is ok, and the way they do it not very hot. Using a solar cooker gets it way hotter and if you hit the 155-162 sweet spot then do this I think you got a nice deal

here is an over view of the sand filter

The sand filtration system I read about many years ago and if you build it right and load it right it will develop a protective layer of bacteria. Lasts about 10 years, so it is a nice investment.
Waterwise and others sell a steam distillation unit that will work off any heat source, in Stainless Steel, it is impressive and maybe 400 bucks, but as there are no moving parts not much can go wrong.
Feel free to move this as I do not know where to put it, and I hope others find this useful!
