Berkey-Style Filter While You Build
Construction weeks are hauled-water weeks.

Why this comes up
Construction weeks are hauled-water weeks. Keep the system in the trailer or the dry room, and feed it water you brought.
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 Big Berkey water filter when that is the job in front of you. Keep the system in the trailer or the dry room, and feed it water you brought.
The limit
Filter water you hauled from a known tap, or water a lab has already tested. A steel crock does not make creek water safe.
The county viewer is the map. The product is only the tool you carry.
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.
