However if you are using tap water it will be chemically treated? OK less so than a pool, but still âstuffâ. Will you try to rid it of that stuff?
We had a naturally fed mare as had a small source, but we didnât swim in it.

That stuff will be burnt up quickly by the sun in as little as 4 hours. Water treatment plant often use flocculent to aid filtration which is sometimes alum based.

You have to give them an email address but no money etc.
Sorry to see that our new member has departed. It would be nice if she came back and told us more.
Shame! I must say it all looked very interesting. I was looking forward to learning more about natural pools. For example, was she expecting still to swim in it, or to just make it a pond?
OH some years back began to find our pool a struggle to keep up for our guests and I was thinking of making the hole in the ground into a sort of hidden seating area with lots of plants and perhaps a fountain to help keep it cool.

Thatâs what we had thought of if we got a house with a pool

Hmm unusual, I wonder if they were really trying to promote swim ponds? One of the companies I know in the UK have a bio filter costing ÂŁ25k, Kate Winslet has one.
Something for everyone to be thinking about⌠I reckon.
This year is possibly setting the scene for future regular heatwaves and droughtsâŚ
with perhaps floods in some areas ⌠who knows.
Whatever.. I donât think one should rely on tap water for swimming pools without putting some sort of means of âcapturingâ rain water, grey water, whatever possible, to ease the strain on the tap water supplies.

No way should grey water go into a pool.

No, no way. As a grey water collector (for the garden), the literature might say itâs 90-whatever % clean but it doesnât pass my sight or smell test. I certainly wouldnât want to swim in it. The SAUR agent even said itâs not to be used on a potager.
Goodness⌠Iâm talking about water used to rinse a lettuce, tomatoes, fruit, or an empty glass/teacup (for example) âŚno suds involved. My garden plants thrive on such offerings, especially in these near drought conditions.
Obviously grey water means vastly different things⌠

I thought it meant that as well as soapy water, Stella, but it doesnât seem to looking online.
You can also save what might normally run away while you wait for the water to be warm enough for washing up, shower, etc.

Weâve been doing that for ages, certainly a year or so.. egged-on by discussions on this forum about saving waterâŚ
4 litres of cold water, before the hot water is actually hot for the first shower⌠
That bucket of water is used to refill bird bath and the hedgehog water spot.. as and when.
we do likewise when running hot for the washing-up, although thatâs downstairs and nearer the hotwater supply so not so much water.. but it all adds up and gets used.

Itâs always worth reminding each other (and newcomers) about useful, important stuff.

I have learnt something. What I referred to as âgrey waterâ is actually âblack waterâ. Iâd not heard the latter expression before. I donât think Iâve ever heard anyone refer to anything other than grey water.
No need to after initial construction if the policy I outlined earlier is followed, that is siting it amongst trees.
I filled my pond directly from the tap in November 2005 and in the more than 20 years since have not added a single drop. This is the current level in the middle of a severe canicule:
The bottom of the board on the other side is the maximum point where it would overflow, it is about 4 or 5 inches below that now but it will replenish when the rain comes and the weather cools.
The cargo strap which I use to pull myself out (in the corner out of picture) is never in the water.

You are very fortunate
and if this heatwave continues, you might find some of us SFâers turning up on your doorstep, asking to take a dip

Depends on their custom and practise, all are welcome but, bear in mind I have not bought swimwear for 30 odd years, when my only cooling opportunity was a drive to a swimming pool or etang.

I have always flushed the loo all my life after using as I donât like urine left in the bowl but for the past few weeks I have been flushing every second time of using apart from number 2. I alternate my toilets too as both take 4L to flush on a full one and use half of that on the semi flush. It should make a difference on my water bill too. As the Tesco ad says, every little helps
