.......... I've been meaning to ask about your pipe/cable hole. Is it actually a hole, or a slot cut in from the side to allow the inverted lid to be removed easily? I'm a bit concerned that a slot would allow warping of the lid from the weight of the pebble topping, but it will be a 'mare to try to lift it up and slide it up the corrugated pipe. I'm thinking about a removable inverted-U shaped clip to hold the ends of the cut rim together.
Mine's a slot. Not had an issue with warping. The slot's only about 1.5" wide and about 2.5" deep. Even inverted, the lid is a close fit on the bin and so it is supported either side of the slot.

Rik,
The other thing I've been meaning to ask you about is in your "How I created the stream" blog post. You say " A mix of 5 parts sand to 1 part cement was slapped, slopped and splodged behind, under and between the rocks ". Did you really use that mix? I'm far from being a 'brickie' or anything related, and I realise that it isn't doing anything structural/load bearing, but but 5:1 seems very weak?

You're right. A 4:1 mix is probably better. In fact, I generally tend to use a 3:1 mix now for most of my small scale jobs around the garden.

I use 4:1 for all the concrete on my railway and it seems sturdy enough.

Thanks both.
I tend to go towards 3& a bit:1( -ish!) for the odd bits of mortar when I need it and given the propensity for my soil to move around and expand and contract I think I'll err towards 3 rather 4 for this job to give it a chance of holding togather. In fact I'm considering laying some sort of mesh reinforcement in the stream bed in case the ground drops underneath. The problem may be in not having enough depth in the mortar to allow the reinforcement to function, plus there is always the chance of a cut edge strand accidentally puncturing the liner, unseen. I don't want to have to do a Rik and dig it all up again to find the leak in a couple of years time!

Evening chaps,

I'm with you on the 3:1 mix for this sort of application. Even for mortar I only drop back to 1:4.

Philip,

The re-inforcing sounds like a really sensible idea. The fear of damage to the liner from metal mesh sounds equally real! Have you considered using plastic mesh for reinforcing. It doesn't have to be 'high tech, you might even manage it with the plastic from the top of 'four packs' of beer. You may need quite a lot of those but gathering the materials should be enjoyable! On a more practical level(!) I bought some plastic non-slip matting for serving trays a few years ago. it came in rolls about 15" wide and about 2 yards long. It was pretty cheap and I think it came off ebay. I think something like that would be ideal. Just a thought. :idea:

Andrew,
Thanks for the plastic mesh idea, brilliant. I don't drink so the 4-pack suggestion is a non-starter but I'm not sure if I still have it but I used to have some semi-rigid 1.5" mesh net which I used on a pergola and would be ideal. I'll have a look when I'm home.

Is the bin a full sized (four foot(ish)) one? Does your stream drain away completely once the pump stops?
Hi Andrew, no it's not a full sized one, its a 70 litre. Can't remember the dims off hand and I'm away for a couple of weeks, will check when I get home.
As promised, the bin is a 70 litre one. which measures a nominal 450mm wide at the top and 540mm deep.

These two pictures show it with the bin full of water having just run the pump to fill the system and then emptied it, so you can see the last dribbles draining back, and then the water level when the system is full and running.

There is about 150mm water covering over the pump whilst running. The red lump on the pump, which you can just about see, is a filter box. The 'proper' one belonging to the pump was too big to sit in the bottom of the bin so I made one from 2mm HIPS with lots of 8mm holes drilled in it. It should do to keep bits of leaf and other debris from circulating.

Thanks philip,

That's useful information. I still seriously considering embarking on some 'aquatic engineering'. This will point me in the right direction. I must re-read Rik's blog on the subject too.

I hope you had a good holiday.

All the best,

Andrew

Always willing to assist, if I can help in any way - though it looks like Philip is now highly accomplished at hydraulic engineering and taken it a stage further.

Thanks Rik,

You remain the pioneer of the 'trickle trade' and the orignator of my awakened interest in the subject!

Thanks Rik, although I'm not sure how justified that praise is! :oops:

However a couple of weeks of enforced idleness has allowed me to mentally play with an idea to solve something that has been niggling at me for ages.
If it works, that accolade may be justified otherwise it will be a candidate for the 'epic failures' thread!

Brilliantly worked out Phillip. Just a little bit of genius ( :idea: ) inspiration we all need sometimes.
