Long time lurker - first time poster...

We live in a fairly high water table area. I collect my sump pump water in a 2ea 65 GAL outside water container for use in my garden. If/when needed - what precautions would I have to take to be able to drink this water (besides portable water filters)?

I'm wondering what type of filter system would I have to build to drink the water?

Also - would the same rules apply to water runoff from my gutters?

Thanks all...
