Hi, my location does not currently have sewage connection, so city ordinance says we'll have to connect. No problem, the sewer line runs right down the middle of the street in front of the building. There currently is a 500L septic system - possibly 2 x 500L tanks underground, I haven't actually opened the system up to take a look yet. I'm not sure you could call it a septic system, since there's no outflow to a field. Anyhow, I was thinking of connecting the septic tanks to the brewery drainage and use it (or them) as a settlement tank in order to reduce BOD. When the system gets full, I could just call the poop truck to suck it up, or alternatively, use a sump pump to lift it into a plastic tank, put the tank on a pickup truck, and haul it out to the hop fields for fertilizer. If possible, I'd also connect the outflow of the 2nd tank, at the top, to the sewer to handle any liquid overflow. The major organic loads would be yeast, trub, mash tun washout, a bit of beer, tank gunk and caustic and acid cleaners - normal brewery stuff.
Any thoughts on this plan? Would I need to treat the effluent or tank water for pH? A fish tank air pump would keep the tank contents from fouling and also help provide some aerobic digestion to reduce solids, would it not? Any complaints the city may have with this plan?
Thanks in advance for any insight.
Cheers,
