RO for a Cabin Fed by a Cistern
Cistern water is stored water. It still needs a test.

Why this comes up
Cistern water is stored water. It still needs a test. RO can be part of a cistern plan after you know what the lab found.
What to check on the map first
County GIS lines are assessment maps. They are not a survey, and a product will not redraw them.
Open Platbookmapper and choose the state. The directory sends you to the county viewer. Match the parcel ID before you trust a pin on an aerial photo.
A tool that matches the job
Shop the Reverse osmosis system when that is the job in front of you. RO can be part of a cistern plan after you know what the lab found.
The limit
Test the well before you buy a system. Reverse osmosis treats a drinking tap. It does not fix every well problem, and it is not a survey tool.
Walk the parcel in daylight before you trust a gadget at dusk.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
