Backyard Aquaponics
A place to discuss aquaponics

We had over 100 mm rain in the last 24 hours. My pond bottom has lifted so what was 600 litres looks to be 300 now. I see no way of fixing it other than pull it all out and do it again.

I have streams under my house, this is not typical weather it's seriously extreme. My underhouse drainage is coping. My greenhouse still doesn't have a gutter and 100 mm rain was just too much.

Looking at the streams under my house I can't see how on Earth I can realistically bury a pond now without 1 metre drainage round it. 300 mm didn't cut it at all.

I'm so glad this happened to me and not a client. Though I aint so happy about it all, y'know...



Flood type rain is like a power outage - sooner or later... says the man with no backup power yet.

bugger!
hope things don't get worse than that!
Keep us posted!

I got out with the spade ond got a lot of water flowing out of there. My mate who's the "phone a friend" I'd always ring on such matters, says it'll go back down and have a real nice smooth seating them whack the drain in 150 ml deeper to ensure the side runoff doesn't choose between the drain and entering greenhouse as the drains lower.

So, a good lesson in drainage for me. If I can get pics of putting solution together I will. Anything deals with 100 mm rainfall in a day should be good to go

My sympathies AA. I find it really hard to get my head around the idea of 100mm being a problem. Our wet seasons regularly involve nights of 100-200mm. There are times when you have to go out and empty the 300mm rain guage to get an accurate reading for the day!
I hope your waters recede and leave everything dry for you!

ah thats why you farm rocks. bloody rains washed the rest away.

good luck getting it all cleaned up AA

absolutely right!

ROFLMAO - quick one there

AD- sounds like you have created a bowl under the liner am I right in thinking this...
U have prolly gone ninize so wont see an answer you til I'm at Jaymie's.
But it sounds like what happens to pools and things like ponds.Hydro static releif valve required or similar to.

Yep there's a bowl under the liner. It's too dark yet to see it today but I'm not overly worried having slept on it. I know the point of entry of the water (the whole ground table...) and how to divert this happening again. The site is on a hillside and will drain.

300 mm's is not 'wet season' Jaymie, it's bloody Noahs Ark revisited.

..and your from the land of the long white cloud?
you will prolly find you do all you have to the still put in a relief valve--socked pipe auto syphon to keep the 'bowl' empty.

We get rain all the time, but it's a little bit a lot. You get none, then everything is dry and caked, then you flood. Flooding here is an accumulation of ground water that may start months of small inputs before it reaches critical mass. 100 mm's in one day on already wet land = too much. On dry land it'd barely feed the topsoil.

If you had topsoil....

I'd need to remove the pond to place the siphon. - Next one.

I disagree.
I'd use a flexi end passed under the liner with a screen(sock)to the edge and then add the bits to finish the syphon on the outside..
just a thought!!
C1..with stuff every where GGGGRRRRR and a 4 hour drive ahead.

While you drove enjoying your beautiful country I sat in a classroom getting drilled on tax for 8 hours.

Count your blessings!

Like the siphon method, thanks i'll do that.

I'd like to see a bit of that 100 mm here north of Adelaide, we've had around 40 mm for the whole of September. Too late to do any good now, crops are gone, but it'd keep the dust down.
