[pure-silver] Re: other new darkroom
I was wondering about the plumbing question. Is it safe to use a gray water drain field for photographic chemistry, or is that an environmentally bad thing to do?
Most of what you generate in the darkroom is wash water. That along with stop bath and spent developer can go to a gray water drain field. Fixer - send it to someone with a silver recovery system. If you are on septic - most residential systems are designed for a maximum rate of 300 gallons/day and a lot of wash water will overload the system
Thanks: I was wondering if the wash water was bad for the soil, but I guess it's not. I dispose of developer and fixer another way, not by pouring down the drain.
