I have a huge hole in my garden, and insted of filling it with dirt, I
am thinking of putting a tank into it, and filling the tank with
rainwater to water my plants from.

If I use a steel tank, that you can get from ebay for 50 quid, will it
simply rust to a useless state in a copule of years ?

Thanks

I doubt it. A son has a huge steel tank in his garden which he uses as a
wildlife pond. Yes, it's rusted but it still holds water after about twelve
years.

With the new bunded tank regs coming in to compulsory force in the autumn,
there should be a flood of non bunded steel stuff up for grabs for free.

Probably. You could try and get hold of a sacrificail anode, magnesium
alloy sold for use in water heaters. There also plastic 1000 litre bulk
storage containers sold on E-bay. Would the hole be suitable to put
down some sand & a pond liner?

What do you do with the "sacrificail anode" ?

I have seen the plastic ones, too small. I am thinking a couple of
thousand gallons.

Thanks

Connect the sacrificial anode to the tank with a bit of insulated cable
and drop it in the bottom of the tank. It will protect the inside of
the tank from corrosion. I don't think it will do anything for the
outside. I believe they protect pipelines with a buried sacrificial
anode, so an external one would probably work in the same way. The
anode will reduce to a small mound of metal corrosion salts in a few
months/years. Then you get another.

A scrap magnesium alloy wheel might work, but I don't know anything
about what's in the alloys used.

Why? Whats wrong with building a masonary bund round your existing tank? Its
cheaper than buying a new double tank and has the advantage that when your
tank is in need of replacement all you need is another single skinned tank.
I always advise my customers to take this road rather than going down the
double plastic tank route

Presumably it is galvanised. We have an old galvanised water tank
lying around out the back, odd patch of rust but nothing serious. It's
been outside at least five years and I wouldn't be surprised to find
out it had been out for the previous 15 to 20 either.

Mind this is in the open so does dry when it's not raining, bit
different to being in the damp ground...

Look into using a proper packaged rainwater harvesting system and put that
tank under the ground. It will eventually pay for itself when on a water
meter. It will also add value to your house.

No.

It takes a long time for rust to penetrate all but the thinnest steel when
it's under water. When it does, in son's case, water will either very
gradually leak out (as it does in a natual pond) or any perforations will be
bunged up with debris which will slow leakage.

As an aside, we have a butyl lined pond which obviously has a leak somewhere
but the level is maintained by rain. One of the jobs on our ToDo list is to
re-line the cavity ...

Heigh ho!

Walls around the tank, so that if the the tank or connections leak, the
spillage is contained and can be cleaned up rather than contaminating
all the local water courses. The bund should be capable of holding the
entire contents of the tank.

110% of the tank contents. And as it's leak proof by nature you may
have to make arrangements for getting water from rain snow etc out of
it.

If I am gonna spend serious money on this, I'll pump free water out
the nearby river. This is an idea to inexpensivly harvest my rain
water. You can take a certain ammount each day without licence. The
pump would be expensive, its only 100m away, but its a big vertical
drop.

I suppose the sort of 2000 gallon tank I am looking at could be used
for loo fluhes and the like as well.

Thanks
Rick

Building your own bund requires two building control inspections plus the
hire of a compactor. That alone should make the double plastic tank route
cheaper.

Strictly speaking you can only abstract water from a water course if
it flows over your own land, and the amount that you can take before
needing a licence is restricted (although it's much more tham most
people would use).

I have not worked out these bunded plastic tanks. To me it seems its
the outer one that will take all the ware & tare, so will likely fail
first, but you won't ever find that out till the inner one fails.

Good one, hadn't thought of that, noted for future reference.
The rate of erosion of the anode depends on the surface area of the
steel it's protecting and the acidity of the water. The little ones
supplied for water heaters would probably last a few months. The ones
I've seen used on steel water tanks were the about the volume of a
football and probably weighed 40 lbs.

200 Gallons is a pretty small tank. "Standard" sizes are 250 gallon 2ftW x
5ftL x 4ftH or 300gallon 2ft x 6ft x 4ft.

They have not come up with your advised system as an alternative.

Possibly because of a preference for do it in a day swap jobs.

Would you like to come up with a ballpark figure for a masonary bund ?


I wouldn't like to quote a price as this can vary wildly in different parts
of the country but you need to work on a concrete base which can support the
weight of the tank, masonary walls either block or brick with a render
lining and an epoxy paint type proofing coat. The volume of the bund should
be such that it can hold a minimum of 110% of the contents of the tank and
this may need to take account of any piers within the bund to support the
tank. The 110% is to take allowance for accumulated rain (NO drain valve is
allowed as someone will surely leave it open
The OFTEC standard books show outline plans for suitable constructions based
on a concrete base about 150mm thick. If you are in a position to do the
work yourself (this is a d-i-y group after all) the material costs should be
minimal based on sand and gravel, concrete blocks, rendering sand, cement,
and epoxy paint. I'd be surprised if materials for a bund for a 300 gallon
tank including base and piers came to more than £150. plus whatever you pay
yourself?
A single skin steel tank from a supplier in Hull would be IRO £140
collected. a double skin plastic tank would be around £700.

There seems to be differing opinon on the best course of action.
I am now currently exploring the regs. to see if I can go unbunded using a
smaller tank.

Cheapest place to get them is a ships chandler. About =A315 a pop. The
biggest UK supplier is M G Duff.

And no, I'm not making that up.


Probably cheaper to use a steel sacrificial anode and connect to a wall
wart, or possibly even mains via a high enough impedance. A reasonable
lump of steel should last long time. I dont know offhand how much
current is needed, but we're talking microamps/milliamps, so nothing
noticeable. Might cost a penny a decade or something.
