The county is genuinely mixed: 3,068 of 6,847 classified parcels are on septic and the rest are sewered. Which side of that line a Erwin address falls on is worth establishing before anything else. The county publishes a records portal that we were able to search without creating an account, which makes checking a specific parcel something you can do yourself in a few minutes.
