Hi Kurt,

Yeah, animal fats clog up main sewers too. Plant based oils such as olive oil have lower melting points so they don't tend to be as bad (on your arteries as well for much the same reasons ;) ).

When we rented in a housing estate whilst building this place, the main sewers became clogged with fats around Christmas time because of all of the cooking fats. True story.

Actually reading over Davids system again it doesn't sound that complex only two mechanical things the air pump and transfer pump. Its just spread out over a few areas and tanks rather than in the one system. It Most likely gives better results that way to.

If you want green lawns just do my trick and leave a garden tap running for 3 days :lol:

I can imagine the town water treatment stations have to deal with some real nasty stuff as most people on town wast water just tip any and everything down there and think it all just vanishes. :lol:

That I would believe.

Even though are not the most pleasant things to clean out. At our farm I'm putting in a grease trap for the kitchen to ensure fats & oils don't go into the septic system, they ruin leech fields and force septic systems to be pumped much more than they need to be. I'd rather clean out a grease trap system occasionally and put the grease into a composting system. Compared to having to redo a leech field or pump out a septic tank. People wonder why things were done the way they were, it's not hard to figure out why they did it, once you follow the path to it's logical conclusion. :mrgreen: . As we move forward we sometimes need to look back.

Getting closer to start building my new house, and have been planning on getting a A&A Worm Farm system, and have mentioned it to a couple of people who turn around and say I'm mad for getting one because of all the problems.

The problems that say that they fail because medications such as anti-biotics, even though they have passed through a human, will kill off the worms in the tanks.

I thought that a bit strange because if medications were going to cause a problem to a worm farm system, they would cause a problem to any closed system like septic tanks or any other HSTP system.

Naturally I would imagine if you tipped a jar of medications down the s-bend, just as pouring a bucket of bleach down there would do too. That'd would screw up all types of systems, not just the worm farm ones.

Hi bpratt,

Don't let opinions be confused with fact. :lol: I've had one of these A&A systems for years. I have never noticed any smell from them and they are able to deal with anti-biotics as and when required. I even occasionally use bleach and haven't noticed any die back in the system.

A couple of minutes ago I just dropped in the food scraps that the chickens or dogs don't want (citrus peel, onions and coffee grounds) and the composting bin is working great. I've never had to empty the system, it just works.

Despite the heat waves, the trenches produce bright green fresh grass which the wallabies, wombats and kangaroos really enjoy.

Just out of interest do the people who are suggesting you are mad have any real world experience with these systems?

It's the old I know someone who knows someone else stories, and usually from the 'competition' (the other type of waste water treatments). I reckon if worm farm treatment plants were affected by passed through antibiotics, then so would these other ones too, and perhaps even moreso, as they are relying a lot on bacteria to do the cleansing, which being smaller in size than worms, could be a lot easier to kill off.

The smell, well I've been on septic tanks for the last 28 years, so the worm farm ones will be a pleasant change. The only odd part will be the 4m high 'stink pipe' off the tank.

The bonus will not just be the quality run off, but food scraps being able to dumped in the top of the tank to feed the worms.

Yeah the plumber who did the house work here told me that his wife used a lot of bleach when they first moved into their house and killed off the bacteria in their system (I can't recall which system). A simple trick to get the "good" bacteria restarted is to add dynamic lifter (basically a mix of composted industrial cow and chook poo). Very clever.

The good thing about worms is that they lay eggs, which can survive for a couple of years, so it is pretty hard to stuff the A&A system up.

Yeah, the vent pipe is the only unusual thing about the system. However, from my understanding it is necessary as it keeps the bio-mass aerated. The whirly gig thing on top will spin all of the time. That was the thing that convinced me that a wind turbine would be a good idea here, however, a wind turbine here was a bad idea. :lol:
