darkroom drain/ septic system
After a 20 year hiatus I'm finally building a new darkroom at home.
The problem I face now is that I live in a well/septic area - no city services for water or sewer.
I know that fixer is a no-no for the septic system, and that developer isn't exactly friendly to the local environment either.
How do any of you in this situation handle wash water drainage? I can recycle the fixer at a local place, and dispose of the deveoloper ( diluted ) in the city sewer system from my office location.
But what are the issues with wash water and safe runoff? Since my well is on my property I'd rather not just send the wash water out to trickle down into my water supply if it poses a hazard.
Thanks for any input.
