I'm considering the idea of converting our 55,000 litre swimming pool
(better known as the money well) into a rainwater tank. It's inground
and made of very thick and solid concrete, with no leaks.
Has anybody out there done this or heard of it being done. From what I
have read, it seems feasible, and the pump on the pool now appears to
be the right power to supply the house.
Any and all hints and tips would be appreciated.
Not sure this is a good idea. How will you treat the water? The same
system that filters and chlorinates the water in the pool does not make
it potable. I think it's a legionaire's
disease/mosquito/cryptosporidium/giardia breeding ground waiting to
I had thought of that as well. My idea was to have a concrete lid built
onto it, with a well sealed access point for cleaning and sludge
removal, along with a filtering system on the inlet points. That is
what the water authorities reccomend on normal tanks. So provided it is
sealed the mosquitos won't be an issue. As to the rest, any info would
The filter system on it currently is a sand system, so there'd be no
Take $100,000 and one gallon of gas. Mix well. Ignite.
You will have the same result as messing with this idea.
Unless you are just thinking of a way to make a swamp, a sewer, or holding
tank for irrigation water.
Okay you'll have to work on the theory that I'm a dummy here, because
never having looked at anything like this before, there are going to be
a lot of theories and situations I have no knowledge on.
Can you explain to me your thinking on this please.
Just keep it simple.
What do you intend to use the water for?
What size of a management program would be required to store and maintain
that quality of water?
Is it worth the cost of building a storage facility when there is water
available from other cheap sources?
The intention is to use it for showering, washing, flushing toilets
etc, we use bottled water for drinking and cooking.
Management program? This is a two storey house..... not getting you
The pool is built, full, and simply needs a well fitted cover, yep
there will be cost there, but I'm working those out as we go.
I don't know where you are Steve, but here in Sydney Australia, we are
under very tight water regulations, and it looks like they are going to
put the price of water up tremendously very soon. Our reservoir here is
currently at around 42% of capacity, and is going down not up.
If it were just that simple. Storing XX,000 gallons of water, and keeping
it safe to use is not a small task.
Even though you say you will only use the water for showering, etc., you can
ingest protozoans that are in the water by simply getting them on your lips
during showering. Protozoans that cause dysentery and that are difficult to
treat, even with modern medicine. Some incidents have been fatal.
Your questioning of the term "management program" indicates that you have
not done a lot of homework on this. What you propose is plausible. It's
doable. But you aren't going to be able to just use your swimming pool as a
water reservoir without some "management program", just as you can't simply
swim in your pool without a "management program" that involves monitoring
and treating the water. And such a simple solution as you propose of adding
a tight fitting cover is not going to be anything that is close to easy.
Good luck in your adventure.
***Wayne: - Precisely why I am asking these questions, obviously there
are those of you out there who have some of the answers.
***Wayne - Which is exactly why all these questions, did you think
these were just random thoughts?
***Wayne - I'm not looking for a simple solution, if there is a
management program neccessary, then that is what will have to be
I truly do appreciate your concern over our health, but have to remind
you that up until two years ago, I lived in the country and lived in a
home serviced by a 500 litre tank. Never had a problem with any
diseases, and it tasted better and more pure than any "town water" I
have ever tasted.
Steve I'm 47 years old, not prone to idylles, simply a better solution
to a problem.
If you aren't going to help with specifics, please leave it to those
who will, there are others on here that have offered possible solutions
Committed to finding out whether this is an economical, sensible way to
Its a interesting idea. theres the cost of the cover, the filter and
pumps to get the water in the house and the cost of power to keep the
water pumps and filters working.
fi;ltering for toliets etc can be kinda crude, showeing demands much
so assume you have this big tank, and are using water.
how will you replenish the tank?
Okay let's take this step by step.
The cover will cost X amount of money which I'm prepared to do, the
filter already exists and is a sand filter, and will cost the same
amount as running this as a swimming pool.
My theory is that as it is adequate as a pool filter, it should be
adequate to filter for showering, washing and toilet flushing, and we
use spring water for drinking and cooking and have done for the last
couple of years.
As to "are you using water", I was considering using alcohol, but as
it's currently full of WATER, and the cost of 55,000 litres of even the
cheapest alcohol in Australia would come to about $120000 dollars, I
figured water was the best way to go.
Therefore, we will use the traditional method of allowing the skies to
administer the additional liquid to the said tank.
For god's sake read the previous posts or don't bother.
I'm sorry to say (ok, not so sorry) that you are way, way off base
there. Large rainwater collection tanks are very common in many parts of
the world and work just fine. Indeed I seem to recall This Old House did
a project in Bermuda and spent most of one episode covering the
rainwater tanks that provide the bulk of the domestic water there.
Thanks for the tip, I'll have a look at their online site to see if
there is some sort of transcript on these systems.
Being in Australia, I haven't seen that show, although it's probably on
I don't see why it wouldn't work Wayne. The way we have been pushed
rain water tanks over the past few years, i am surprised that I have
not heard of the idea before. There are many older houses around
Sydney that have underground storage tanks and that is really all that
you are proposing. It would be easy to channel rainwater into it and
the standard pump would be adequate to get the water out of it. You
may want to think about a smaller, elevated intermediate tank with a
float valve to act a s a buffer between the pool and the house.
How about talking to someone like Dural Irrigation for some ideas.
Now if I can only convince the better half that we don't need the
I have sent a query to another irrigation specialist, but will give
Dural a go as well, the more the merrier I say. I dont know that this
has been tried before, but I'm determined that either this will happen
or it will become a hole filled with dirt. No more money drain for me
Thanks for the lead. I'll keep posting here to keep things up to date.
