text: well i dont actually own a piggery, my stepfather does.  It operates on our farm here.  We lease it out to people who supple the pigs.  We feed them and maintain the piggery and they pay us to do so.  On some occasions the piggery does smell pretty bad due to all the waste.  However we have an anearobic dam that breaks down the waste once it leaves the piggerey.  We then pump the waste out onto the grass helps it to grow.  The only problem I have with the piggery is the smell, especially when its going to rain.
