    Starting a brewpub on septic. looking for advise on treating wastewater and disposal.

    Hi there,
    First time poster, long time reader.
    Putting a brewpub on septic. I'm sure there are a lot of reasons why not. But we are going for it.
    System is 8bbl but will probably start with about half that.
    This location used to be a restaurant. Including 3 inline grease traps before the septic, Then 3 septic tanks followed by a tertiary effluent filter box full of filter media. Water is very good after this process.
    I would like to not tax the septic when possible.
    I've heard some people storing waste water, adjusting the ph and just letting it go on the property. I'm not sure I'll be allowed to do that.
    I'd like to hear if anyone has any ideas for keeping wastewater down, or treatment of it and ideas? Maybe the farmer next door would love it if I watered his or her crops once the water is within the desired readings.
    Thanks so much!

    I am sure you've already thought of this, but you can save water run through the chiller for use in cleaning, etc. Alternatively, since you're in Canada where outside temps are equal or below ground water temps for at least half the year, you could run chiller water back and forth between two water tanks outside, instead of sending any to your septic.

    Use for surface water irrigation

    Hello Ward1BrewingCo,

    Our brewery is in rural Placer County, California. With permission from the state water board, we simply put the process water into tanks (6000 gallon) and use it for onsite irrigation (hops, mandarins, and blackberries) at our Farm Brewery once we filter out the solids (sand filter). We batch it so the BOD and nutrient load is relatively uniform. Works great and a nice way to recycle water.

    The BOD from process water is way too high to go into your leach fields. It will forms a biomass (slime) on the trench sidewalls in no time and plug the entire system. You will then have to install a new one ($$$$), if you have the land for it.

    Good luck,

    Earl

    That is a great idea I did not think of that. Thanks very much!

    Thanks a lot Earl! This is great to hear. Could you recommend a sand filter? Also, what are you doing with the solids from the filter? Or does that just get pitched with the filter cartridges?
    Thank you again, this is so damn exciting!

    I haven't actually done it yet, but the plan is to use two stacked 250 gallon plastic totes. You can get them off Kijiji for a couple hundred bucks. Average daily temp in Nova Scotia never drops below about -6 C for extended periods of time, so I think I could get away with just electric wrap on the piping to stop freezing, and otherwise rely on the large thermal mass and the input of heat from brewing for the tanks. Ontario's a bit of a different scenario, but you can buy trough/tank immersion heaters for <$100. That's what we used on our farm in Northern BC growing up. Worked great. For example: https://www.tractorsupply.com/tsc/pr...icer-1500-watt Set up would have the advantage of making available near zero degree water for large parts of the year, greatly increasing cooling efficiency.

    Use for surface water irrigation

    Hello Ward1BrewingCo,

    The filter system will need to be sized based on the anticipated flow and amount of bio solids. Also, build in a second (redundant) filter in case the first one clogs. You can go to a farm irrigation company or a good engineer to size it (usually, the farm irrigation company is cheaper). As far as purchasing a filter, there are many. That same farm irrigation company or a pool supply company have the filters (based on the size you need).

    As far as the bio solids, I simply use them for compost for my hops, mandarins, and berries. I don't get too much in the filter as most settles out in the storage tanks and have to be cleaned out once in a while. Note: don't put the intake to your filtration system at the bottom of the tank; you will suck up the solids.

    Based on the design, you could probably use filter cartilages rater than sand filters. I just happened to have a couple of sand filter laying around.

    Good luck,

    Earl

    If you are looking at which kind of drains to be putting in your floor you should check out Blucherpipe.com/breweries. We have had much success in the craft brewers space when it comes to saving water and cutting clean out time. Mad Tree Brewing in Cincinnati OH is saving over 1000k gallons of water per year with the Hygienic Pro stainless steel trench drain installed.

    Let me know if you have any questions,
