anybody have any creative ideas for a septic design to work with high water table? I bought my property about 3 years ago with the idea that we could divide it and build another house on the property. We have everything lined up except our septic system. First the county told me I need 6 holes with at least 24" dry soil. Got it. Should be good right? No. They tell me they don't like the color of the soils so they want to perform a "wet season review" so they come out in the middle of winter and check again and I need 12" of dry soil. Well, I only had 1/6 holes meet this requirement. I had a couple at 6" and 8" and the rest were pretty much right at ground level.
Any ideas would be appreciated. I live in Washington State if that makes a difference.
