Browse Forums Building A New House 1 Jun 27, 2007 7:23 pm We've just been told we have at least a 9000L tank to pass BASIX.
I'm looking at my plan (see blog link in signature) trying to work out where to put it. I was hoping to put it near the laundry at the corner of the house. I'm imagining the tank needs to be quite close to the gutters but at the moment we have a 1.2m offset from the boundary on that side and the tank would extend past, and cover the door then. Does anyone have more info on how this could work? Just how close does the tank need to be to the house considering there needs to be a pump etc there and return feeds to the house for toilets and laundry use. Re: Water tanks 2Jun 27, 2007 7:31 pm holy cow that's a large tank!
an option would be 3 x 3000L slimline tanks - but that's going to get pricey. The cheaper tanks seem to be the round poly ones. what about putting it underground? maybe even a concrete tank.

The cheaper tanks seem to be the round poly ones. what about putting it underground? maybe even a concrete tank. That's for sure! The slimline 3000L tank set is 3x the price of a 9000 round poly one, and I'd need 3 sets!! I wonder how much the excavation etc would be for an underground one... It's because we have just under 1200m2 block, with only 200 odd covered with house.

I need a smaller block. ![]() If I built a bigger house that had more bedrooms then all the other calculations would increase I think because I would have capacity for another user... It would be good to have some time to play with the BASIX calculator to see just how to manipulate it best.

I'm doing a favour for mum and putting one in her place. One thing that I've found is that you can have the take quite some distance away if you use a wet pipe system or install it as a wet pipe system but use an underground diverter. You'll have to have a read to understand it fully: http://www.rainharvesting.com.au/wet_systems.asp As for pumps, the problem is the height that the water has be pushed. Re: Water tanks 7Jun 27, 2007 10:38 pm You could also consider bladder tanks - they're basically slung underneath the house. One I've looked at briefly is http://www.rainreviva.com.au though I've been told by the staff at our local environment shop that there are other businesses that might offer better service. I think they mentioned the "Aussie Bladder" ![]() ![]() ![]() I have no idea how these compare to slim line or other tanks in terms of price. I'm about to post a new thread to alert people to another approach to water collection (namely fitting a kids swimming pool underneath the decking) that I just read about in Renew magazine. But it wouldn't work for you with BASIX because I don't think it would pass the bureaucratic hoops. Pity ... the guy who wrote the article put his in for about $350 ($200 for the pool and $150 to dig it in) and has storage capacity for 7000 litres. He's connected it to his other tanks, so they all run off one pump. Anyway, back to bladders, just google bladder tanks and you'll find lots of options. My advice would be to contact a proper green plumber - there's a lotta ******* operators out there. See http://www.greenplumbers.com.aufor more info. e. Re: Water tanks 8Jun 27, 2007 10:55 pm I’m doing 2 slim line tanks that will follow my walls. I don’t have the space to put the big round ones in…..been here 20 years….there’s a lot of gardens!
That’s a big tank…..they must be really cracking down now! What happened to……Get rid of the water tanks?

That 'underneath' word represents a bit of a problem right there - we're building a slab house. They'd be perfect otherwise. Re: Water tanks 10Jun 27, 2007 11:11 pm Ah, I see. Another reason for me not to be moaning about having to build min 600mm above ground! (flood levels and all that).
Oh well, might be useful for someone else reading this thread in the future. G'night! e.

It's because we have just under 1200m2 block, with only 200 odd covered with house. FYI, our builder charge us about $8000 for a 3000L slime line water tank (with all connection, motor, filters, ...etc all included). To replace it with an underground one in similar size, they charge extra $5000.

Re: Water tanks 12Jun 28, 2007 8:46 am ![]() I wonder how much the excavation etc would be for an underground one... We've been told that ball park range for underground tanks is about $10k (excavation, electrical, plumbing) - cheaper if you know someone in the excavation business. A 10k L tank in concrete was relatively cheap - about $5k. Re: Water tanks 13Jun 28, 2007 9:23 am Basix assumes that because you have a big block, you will have a big garden, hence be a heavy water user and require a large rainwater tank.
You can reduce the need for water in Basix by nominating more area to indigenous planting which won't require water. Definitely play around in the Basix website to see what suits you better, or ask your Basix consultant to change it. You should be able to use a tank of 4-5000 litres. Re: Water tanks 15Jun 28, 2007 10:29 am Bud - that's what we thought until we found out about the $10k installation costs!
I think we will be in a similar situation as our block is 880m2 with a house footprint of about 200m2. Luckily, we are in a recycled water area (Schofields) and so BASIX doesn't require a tank - however, we will put one in anyway.

We've already done that with half our block! ![]() Re: Water tanks 17Jun 29, 2007 4:40 pm Make sure you nominate 3 star taps and showers.
I'd get a BASIX consultant to look at it. I tried doing my own certificate and came out with loads of requirements, but the builder's one is much better. ![]() Building a Jandson Espirit in Pennant Hills "What is the use of a home, if you haven't got a tolerable planet to put it on?"Henry Daniel Thereau Re: Water tanks 18Jun 30, 2007 11:35 pm What sort of tanks are you guys talking about, because you could get a lot cheaper tanks than that!!!
$8000 for a 3000L sounds like $3000 for tank and pump and filters (at a stretch) - $5000 for the builders pocket!!! Hope you aren't getting ripped off.
