Bill, I saw the recent kickstarter post and it mentioned the darkroom. It's funny that I assumed there'd be a darkroom but never gave thought about how you were going to deal with the waste water. The site seems fairly remote from public sewer systems and I would guess that in that area in general most commonly septic systems are used. Do you have access to public sewer or have you come up with an alternative means for chemical waste water? I ask that because I have considered building a house in an area without access to a sewer and was hoping that maybe you had a solution I have not considered.
