best value water tanks??

 

Hi, I live in the lowerbluemountains SYD, (10 mins Penrith) and really
want to  splurge on a large watertank 9000 - 20000litres. Really
confused what to get,  I want the best value tank that will last at
least 20 yrs.  Anyone know any bargains out there??   There are a few
sellers on EBAY but worried buying sight unseen.   If I connect it to
the growing shed and not the house do I still get a govt rebate?  Any
tips appreciated.

In my view the polymer ones are best.  The polymer is UV stablized and they
have been in use for long enough to be sure that they will actually last.
Also they come in various colours and don't need painting.  Concrete will
crack (especially on clay soil) and are very heavy, and galvanised iron will
rust (especially near the sea or in a polluted area).  I have three polymer
ones from Bushman and I am happy with them.

As these things are rather large you need to include delivery when comparing
prices.  The price per kilolitre decreases with tank size.

Something you need to work out is how in advance is how to re-arrange your
roof plumbing to capture the maximum amount of water, this is not so easy if
it was built to discharge at 3 or 4 different places.  The simple solution
is to block the ends or downpipes where you don't want the water.  This is
not ideal as some of the guttering is likely to fall the wrong way this can
shorten its life and accumulate muck as pools will form at the low points
where the water can no longer escape.  Also if all your roof water comes
down to a single pipe the guttering is very likely to overflow in heavy rain
as the pipe will be inadequate.  This will waste water and may damage your
house.  If you are not experienced in this you may need a plumber.

Just to add 2c to the discussion.
If you are in a place bordering bushland, you might want to
reconsider poly tanks if you are relying on them to assist in fire
fighting, but if that is a serious consideration, then you'll have a
diesel powered pump in a brick enclosure and roof sprinklers as well I
guess.

I'm also thinking about repairing them. The old gal (new = colorbond)
could be easily repaired with a piece of tin and sticky goo. they seem to
rust out in the bottom if never cleaned out. I guess you'll need to be
able to fibreglass to properly repair a poly tank (anyone done it).

Generally get the biggest tank you can and make sure the ground under it
is VERY stable and compacted.

After you work out how to get the tank into place, you also need to
investigae all the costs.  If you are going for the rebates,then you have
to hire professinals (plumber and electrician(?) AFAIK to sign off.



Start from the top.
Work out how to keep leaves out of the gutter, but make sure you can
clean/flush the gutter as they are not the only crap that gets their (all
filters have small bits fall through, plus flower parts, bugs,
etc).

Then have a leaf diverter below the outlet and work out where the leaf
diverter is going throw the leaves and a bit of moisture.

The "sydney standard" says I should have 3x100mm down pipes. Like everyone
else, I have 2x90mm, but my front downpipes are long horizontal runs down
each side of the house. Different yes, but I'd loose most of my
water if I didn't. Until SWMBO agrees to replace the front lawn
with a mega tank, then it stays that way.

Long horizontal runs are leaf catchers, which is why I mentioned the two
steps above.

I also have a first flush diverter (put T vertical just before the
downpipes(2 on each tank) enter the tanks(2).

Great to deal with.
If you are looking for rebates then "play it straight", anything else
may well not realise your expectations.
There is no requirement in Qld to advertise the exact location and
hydraulics for the purpose of claiming a rebate.

g'day george,

around the 22 to 25k litre size are agood size you could go to around
the 32k size if you have capacity to do so that is space.

i find dealing with the long time in business rural tank makers is
always better their product has stood the test of time and their
prices aren't directly driven by the gov rebate like those johnny come
lately city makers. they will also site the tank(s) where you want
it/them so long as you have access.

the supplier should also be able to sell you a pump as part of the
deal, i would suggest a 4 tap pump that will be able to service the
whole house if need be, they cost around the $600 mark, we also now
ahve a preferenc to air bladder type pressure pumps, now got no faith
in these electronic controlled pressure devices.

and if you need ot buy that cheap as floating ball cock type diverter.
