Hi,
We have had some round treated pine fence posts installed recently (they look green).
We'd like to paint them, but everything I've read seems to recommend acrylic paint (something to do…

Hi SaveH20,
In the above scenario, we reduced a 90mm overflow (on a 2500L water tank) to a 50mm PVC pipe. We buried the PVC pipe 100mm underground, then brought…

Such a helpful response - thank you. I learned a lot from what you shared and saved the post for future reference.
What you’ve outlined (best practice tips)…

Hi SaveH20,
I have a random question for you please...
Our water tanks (the three of them) have inlet screens that sit at an angle on the water tanks. But I've…

That's very helpful - thank you.

I have another question for your please...
Instead of reducing the overflow pipe from 90mm to 50mm just below the overflow outlet, we were thinking of sticking to a 90mm overflow…

Thanks - I'll purchase several different degree bends and see what works best.
I tried heating up a 50mm pipe using a hairdryer today! I can't say I succeeded. …

Ah yes, you’re right - makes sense (thank you). I should have figured that out myself.
Thanks, I’ll go with an 88 degree bend and a 15 degree bend. …

The timber around the tanks is H4 sleepers. I don’t believe they should rot.
I don’t understand why I need two 45s. I am going to set up the overflow as…

I thought of drilling holes in the wood, too. It might actually work ok because the land falls away from the tank base and into a garden of trees.
Thank…

Ok, I’ll use the reducer you recommended.
Ok, we will bury the 50mm pipe. How deep do you think it would need to be buried to make it safe to go…

Thank you - that's super helpful.
Should I use this reducer:

Or this one?

If we left the 50mm DWV pipe on the ground surface (instead of burying it), would we be able…

Hi SaveH2O,
I realise this is an old thread but I have a related question please.
We purchased a small water tank (2500L) for our animal barn (roof = 26m2). Water…

That's very helpful, thank you. I was mostly interested in knowing if a spoon drain requires a specific slope, but I appreciate the extra information.

Do you mean land slope for open surface drainage or pipe slope for subsurface stormwater drainage?[/
I would love to know both please. Thanks

Hi,
What is the absolute minimum fall land should have for sufficient rain water drainage?
Thanks.

groundzero We are going to start with the trench along the neighbours boundary, as suggested (we organised someone to do it for us).…

groundzero Could you please share your thoughts on the following:

If we installed a cut off drain along the neighbour's entire fence line (in…

We would manage it if it was installed. But it never was. The land was never graded away from our property, nor were temporary downpipes used.

Yes, it looks amazing, but we won't be paying for that. Surface drainage on highly reactive soil is the responsibility of the builder.

Tried digging a small pit in the animal paddock and it was impossible! Ground is as hard as a rock. Will attempt it again after some rain. …

I will do, thanks. We are in the Western suburbs of Melbourne.

If we had built this house, we would have done things very differently. But we are the second owners, and we're just trying to do our best with a…

I agree that a cutoff drain would be better than a spoon drain near our neighbour’s fence line.
What is the difference between fill versus natural topsoil over natural clay? …

That makes sense - thank you.
The animal paddock is ours. It's about 30m wide, so that's roughly the distance between the neighbour's fenceline and our house.
I will carry out…

That diagram is very helpful - thank you.
I don’t understand what the cutoff drain in the animal paddock is for? Is that to stop the neighbour’s water from approaching…

I’m sorry the link doesn’t work - I just double checked it and it should work. I’ll try uploading a picture.
Thanks so much for that very helpful information. It makes…

Great diagram - thank you.
So are you saying the trench could be backfilled with soil (+ sand/gravel) and we could omit the agi pipe? How would we get the…

That looks brilliant and it makes perfect sense, but I wonder how much something like that will cost us?
Does the crushed rock above the agi pipe have to remain crushed…

Our soil report states H2/P. So I guess it's both?
Do you mean that at the end of the builders plastic the agi pipe would have to drop 600-600mm into…
