How typical of men on this forum to write...." One shouldn't believe all one reads....
......EXCEPT of course the dictat (ph) of the  FORUM EXPERTS.

You boys really are something else..... :hee20hee20hee:

My favourite tipple is wine. I always say " If it was good enough for Jesus, it's good enough for me " .  :72:

The ordinary people in times gone by drank beer, because it was safer than most supplies of  drinking water. In the UK, there
was " small ale" or ' big ale", depending on the strength. ( I may not have quoted the exact phrases. )

Staying on the water theme and to LIGHTEN up the mood  we  have just returned from church where the head honco  gave a lovely sermon on the marriage feast at Cana.
there jesus turned the water into wine and everybody had a great wedding. Some were so merry they had to hire  lorenzos chariot to take them home.
now why would the sun of god and a holy man turn clean water into a horrible alchohol based drink.
Maybe the water quality in Cana is similar to the brown stuff that comes out of our taps after the heavy rain.
i dont have the answer to that but Jesus will be first on my invitation list the next time i invite my only two friends or maybe three round for a few drinks.
Please no anti  religion posts.  
HAve a great day all  including the lovely jessica.xx

JessicaH if you read my post its states ABOUT 3ppm. On average an outdoor pool in warmer climates should be kept at levels between 2/3ppm as the Sun will burn the levels down during the day.  If you only have 1.5ppm on  a really hot day the level could be zero at the end of the day, then you have no protection. Indoor pools where the Sun does not affect ( only pool heaters) should be kept around 1.5/2ppm. This is lower due to the fact that chlorine fumes within a building can harm/ affect people with breathing problems. I think you may be getting information from sites that only give basic information  (American usually)
Also I hope you do not believe everything that you read as they are misleading at times. For example:-
The World Health Organization has raised its safe level for chlorine in drinking water to to 5ppm.  This is to combat bacteria in water in Africa, but doctors are now finding that this level is causing just as much harm as the bacteria. Do you think that they are going to own up to this? Until the chlorine kills more people than the bacteria nothing will be done.
I didn't mean to offend only clarify and this will be the last time I will respond to this thread or any other.

Fact JessicaH if you drink water with 20/25 ppm chlorine make sure 1.  you are in a hospital 2. You have a preacher. Because you will need Both!
I have lived in Spain since 2000 and the thing that gets my back up is that because someone has a pool , overnight they become experts in water chemistry .


Am just quoting what many sites on www state.  So arrogant responses not necessary especially as I have NEVER said I was an expert in the subject but mearly stating the truth as I see it and read it.
The recommended outdoor home pool the acceptable level is 1.5ppm NOT the 3ppm you stated and it was because you wrote this I decided to investigate further.

raysun, Suggest you stick to your Irish ??? whiskey, because swimming and imbibing in sufficient alcohol to kill  :32 is not a good idea...

Because for 11 years we have back washed onto our garden without problem to plants and sans corrosion thought to do some research on this interesting subject and came up with this snippet that appears to be at odds with the forum experts. 

"Drinking water in fact has 3 to 5 times more chlorine that pool water.  :040:
Normal home pool water has 1.5 to 2 ppm chlorine, drinking water has 20 to 25 ppm chlorine.
There may be other chemicals in pool water that some people put in.
So chlorine is not a problem, but there may be other chemicals like water qualifiers and de foamers.
We use drinking water to water plants all the time - so its ok to use pool water, just don't use for 3 to 4 day after adding chlorine"

IMO the MAIN cause of the problem is when people refer to "backwashing " it is not the recommended way but via waste which pumps out water by the gallons.

Thanks you 1dezza2 - I rest my case Chisme.

Right let's get the facts of chlorine in tap water and pool water.
Tap water chlorine rate is 0.002ppm
Pool chlorine around 3.0ppm
I think there is a big difference don't you?
Tell me would anybody drink household bleach? Bleach and chlorine are virtually the same - sodium Hypochlorite.
Household bleach is between 3%to 6% pool chlorine between10% to 12%. So if anybody wants to drink it carry on.
Now can you see why it shouldn't be dumped on the street ?
If you want to know my background it's over 40years as a water treatment engineer / consultant to various water boards and hospitals.
I hope this clears up this thread.

For the last 11 years we have back washed straight onto our garden.
Although having always kept the chlorine high not only does it make our grass and flowers flourish but we dont even have the mearest indentation in the soft soil..which might occur if people backwash to waste thus draining the pool instead of. 20 second flush through.
Irrespctive of the legality it is a total waste to backwash onto the road instead of ones garden but cannot fathom how any of the chemicals, legally permitted for use in a swimming pool, could cause endangerment to the environment or damage Tarmac.

byrney

Clearly there is no point in discussing this with you further.  There is far more chlorine and other chemicals in my pool than there is in normal tap water, which is the point I was making.

You will remain unconvinced and continue to swallow copious amounts whilst swimming.  I swim and never swallow water - so I don't know what you are doing wrong.

Anyway, let's leave it to the Town Hall and Police to decide what's legal and what isn't, eh?

So Chisme, you settle down with a nice glass of pool water then do you?  Of course there are more chemicals in pool water - I know as I put them in !!!

Do you mean chlorine? It's in such minute quantities and chlorine is in tap water too!

I don't settle down, as you so cynically put it, with a glass of pool water, but I do swallow a lot when swimming - it does me no harm!

Lets look at it from another perspective. If there is any danger to public health, do you really think Europe, with it's concerns about 'health and safety', would permit pool ownership or even pool swimming?

But however sensible the arguments, I'm sure the urban myths are more captivating and will prevail.....

"Nosun tap water and pool water nearly the same" - where do you get that from?  Nonsense.

Byrney,

If, as you claim, Nosun's comment is 'nonsense', could you please let us know what's different (assuming no-one's been urinating in either)?

What chemical might be in one but not the other?

There seems to be a lot of strange urban myth surrounding the properties of pool water and its danger to the environment!

Regular nut 🥜

Well you can drink coke but you can also clean a toilet and things with it, so I expect same principle.

guest4538

What is this dangerous chemical in pool water which is capable of destroying plants and roads whilst apparently harmless to humans?


tandas

Forth pool emptied down our road for maintenance!  Good job the Spanish couple who live there are not doing so at the moment!

Nosun tap water and pool water nearly the same. I think you a miss informed.

I live under the Zurgena area and today two locals have backwashed into the road again, and the road is breaking up, in the vicinity of where one of the local councillors lives.
Just as the dog owners wander the roads with dogs off lead allowing their dogs to defecating where they will and not cleaning it up 
So much for rules and laws, which unless they are vigorously enforced mean absolutely nothing
Then again judging by previous posts on a range of subjects it seems some select which laws the accept and which they dont according to if it affects them.   

aussie

When we enquired at ZURGENA town hall we was told it IS illegal to back wash on to roads and there is a fine for this.
They said the chemicals eventually damage the roads

Hi all,
Is it OK to Backwash pool water direct into Potho?

Thanks for any assistance.

no coz you will fill yer potho with water,just chuck the backwash on yer land or patio its should soon dry out.

Also too much chlorine could kill off the good bacteria that are digesting the solid matter

Amanda Oakley

Back to basics..................
Water is a "luxury" ítem in this part of Spain which we should all respect........
Use the backwash water in your gardens, respect disposal of this water if running onto someone elses property or public land (ie. roads etc) and learn to speak enough Spanish to ask for local advice if in doubt !!!!!!

Makes you wonder if those who have pools which don't backwash into the waste water system ever received permission to install them.......

KJH3

Nosun, it's such a shame that some don't agree with you, frankly it's selfish and arrogant and it damages roads, the damage where I am is severe, there is not many days a week when water is not flowing down the street away from their properties.

Just seen this post very interesting my next door is ruining the road it has all sunk they are the only people whom empty into the street, I have now taken photos of it coming out of the hole in the wall and informed the town hall as I have spoken to the tenant  but just got abused, spoke to the landlord about the barking dogs and got no where as all he is interested in is is rent, so thought no point saying about pool to him go straight to town hall. They have at least now taken the pipe into their own property, so let's hope it lasts. Can not see how much longer the road is going to last now as it is all sunk and the main drains is going to collapse if we get a heavy truck come this way.

Backwashing is just not about clearing the filter of dirt/dust, it is about cleaning the filter of bacteria. Bacteria can hide out in the filter and chlorine alone will not sort this out. So for a few cents worth of water give the filter a good backwash.

stean

why are you backwashing every week, I vac my pool 2 or 3 times a week but I havn't backwashed for about 6 weeks or more. Have you not got a dial that goes from green to red on the top of your sand filter to let you know when to backwash, also only backwash until the water turns from brown to clear approx 1 minute then 20 or 25 seconds on rinse.

uslot

I backwash straight onto the garden, only a splash pool so it's not a lot of water and soaks in very quickly. I imagine with a large pool there would be a lot more water, which would not just soak in. A barrel therefore would allow you to only release a small amount of water at a time. A watering can rather than a hose, if you see what I mean.

JessicaH

All our the water, except from all but the toilets, is dispersed straight onto our garden.
Everything thrives because, thinking logically, any detergent or chlorine used is automatically diluted.

So backwash straight onto your garden and wash it away unless you have an area you don't give a damn about. Barrels control the flow. As for what happens when it rains the same thing gets into the cracks and undermines the tarmac but at least it's natural. The Spanish house at the bottom of our road had to erect kerb stones to keep the backflush water from flooding their frontage every week.

How do barrels control the flow? Are these smart barrels?

The Spanish owner of the house at the bottom of Calle Arbuli, added channels in the road to direct any pool water, which had been discharged into the road, directly onto his land. He was sensibly grateful for any free water!
