I would say you could have issues in the city due to the size of the land .

The big issue I have is power, that's why we went traditional septic, it does not use any power at all.

I'd heard that company had gone out of business in at least Australia, and were known to have issues.

Yes it was in Au actualy on the sunshine coast hinterland so very local . A NZ company has taken ownership now. They are made there now but available in AU.

They don't have troubles but a lot were installed incorrectly . For example installig them below then ground at the lowest point in the block. Then when the system floods and the worm drown they wonder why. The top 30cm or so needs to be above ground and not at the low point of the block. Simple but often overlooked.


It's just a tank with mesh bags, filter cloth a pump and worms, not much to it .

Hi bpratt,

I have an A&A wormfarm here and it is genius! I'm on the side of a hill and the whole system operates by gravity - no alarms - no pumps to break down - and no fan. Awesome!

Better still, the system never requires desludging so it is virtually maintenance free.

The trenches are about 80m long here and they keep the grass / herbage green over summer so the wombats, wallabies and roos keep off (mostly) my vegies.

The internal plumbing is identical to a normal house so visitors are unaware that the worms, slugs, bacteria, fungi etc are eating their poo!

The only downside is that you can't chuck large amounts of chemicals into it as it is a biological system. The plumber here was telling me that his wife went hard on cleaning their house using bleach with a similar system (Taylex) and it killed the whole system. He restarted it with a bit of dynamic lifter.

You won't regret the purchase!

Septic system do use power when they eventually fill up and are then required to be desludged. It all depends on how much water you use.

The wormfarm uses aerobic composting which is why it has virtually no smell. I scare visitors by daring them to poke their heads into the system (you can chuck your vegie scraps in there) and take a deep breath.

Septic systems use anaerobic (ie. no air) bacteria and they stink!

My system is rated to cope with 1,800L of water per day and being on tank water, I'd be pretty grumpy if someone used that much here! :lol:

Yes a "honey truck" for that. Minor issue, if you use a septic tank correctly that can take a longtime indeed, my grandmothers house from when I was a kid, way long time ago, had a septic tank it took 25 years before it needed desludging as my father told me when he was alive, I''ll have a grey water system anyway the amount of water going into the septic system will be 1/3 to 1/4 maybe less compared to what might typically be seen so detention time will be much longer.

If you can get the anaerobic bacteria really "cooking" then it may take even longer between pumpouts, I was at one farm a little while ago the farmer their I've known for a quite a few years he used a truly freshly dead cat, to get bacteria in his septic tank to really ramp up again surprisingly it really did help get it really going well again, gees it made for a funny story. :lol: his desludging is now at in excess of 20 years since the last one and it's still not half full, which is technically the trigger point for a pump out.

Hell yes, they can. Particularly if the septic is mistreated, ie fed lots of poisons on a regular basis they like us really don't like being regularly poisoned, that's one of the main reasons for premature septic system and leech field failures. People keep poisoning them by putting stuff into them that make the toilet smell nice and kill all the bacteria. Those are the very bacteria that are critical for a septic system to function correctly, the end result is a truly bad stinking system, if you know of any that really stink bad, ask some questions it's not hard to figure what has been done to it.

A simple rule is if it will kill all bacteria or it's a poison then it will kill a septic system, avoid it if at all possible.

Treat septics properly, they will last for decades without any real work being required, some septic systems have been functioning properly for over 100 years with only the odd desludging every xx number of years and the leech field is still functioning even after a century of use. It's like anything treat it the right way it will last a really long time indeed. Do the worng thing and you will pay for it.

BTW, for what it's worht it could make for a methane gas collection system, say for a gas hot water unit or BBQ maybe. I'm not sure I would use the methane inside a house for a gas stove at least not without doing some proper testing and filtering anyway :lol:

Hi davidg,

All of that is so true. The system is only as good as the people that use it. If people constantly poison their systems then they will find that no matter how good the system could be - it will fail.

Because the worm farm takes all of the organic scraps that the chooks and dogs don't want, I check the system out here most days.

If you don't require certification for occupancy, then there is really no technical reason (legal is another matter altogether) why you couldn't build and maintain your own system - as long as you don't annoy your neighbours!

We do, it's kind of hard to miss our house once it built initially however once the bushing goes in that will make it hard to see from the Hume Freeway, ATM it will be very easy to see it though, once it's built.

Ah well, then all you need is an old well built "long drop" outhouse :lol: with a long chimney vent stack, painted black that will draw the air though the "thunder box" and out the chimney stack vent continuously, very simple just don't poison it. :lol:

Yes the septic tanks do last a long time. My old man would have had his on the farm for around 37 years. That said I think I remember it being pumped at least once when I was a kid and I'm not sure if it has been done again. Not to shabby.

Though when you get a lot of rain or go silly on the showers (Xmas time lots of guests) I do remember siphoning antics going on from the vent pipe to the paddock out back. Hey suck on this pipe :lol:

The system we have doesn't need to have a pump you can just use gravity. We have a huge hill just 5 meters from the tank but I think they chose to pump the water out underground to the lawn that is flat as us a nice and level if not slightly up hill from the tank. Gives us a nice green lawn all year rather than just watering the scrub below us. The energy consumption isn't that much if it was I would be the first to complain about it and try and fix the issue.
