Then it's very possible at least some of the water is from your septic
system.


Just called the folks at the county (Wake County, NC 919 856-7400) and gave
them my address. They will research the property and let me know in 3-5 days
what they find on the original septic plan..

Good plan, wish I'd thought of it :-)
