I am also in Okanogan County (Methow Valley) and am researching this post because I'm facing the prospect of needing to put in an expensive septic to be able to permit and build my home (owner-builder). Has anyone in Okanogan County been able to successfully permit a composting toilet and greywater system? The greywater seems like it could be more of the hangup for the septic requirement. Unfortunately, the soil drains too well here and I may be required to pay a licensed installer to put in a pressured septic with a 20K price tag! All my closest neighbors have had to do this. Any potential workarounds? Would much prefer to put in a composting system and greywater system. Thanks.
