Agreed its chunky and modern. Not agricultural imo.

One of the great disciplines on BH is saying nothing when you have nothing to say. But I'm experienced in this, so it is duty to say...I don’t know. Lindab is seriously good. So if they have a ready made product that suits, then use it. But I'm assuming the question is about an internal gutter, fabricated then galvanised. In such a situation I haven't heard of aluminium being used. Maybe it can. But the reasons against it may be strength and durability.

You can paint the inside of the gutter with bitumen paint. We used to have such paint supplied as standard along with internal gutters. It had the physical advantages of stopping any repetitive drips from wearing the galv off, and extra sealing at joints. Now I think of it, there was aluminium dust mixed in which rose to the surface, which returned the sheen for reflecting the sun. I've no idea if that is a standard product. Use bitumen paint anyway and it will do what you need. I would not recommend an internally colour coated metal. It will laminate in time and the galvanising coat is minimal.

MacDonald's ratio?

Which could reduce the total number of turbines required.

But it is very complex. Will the powers (I know) communicate? Ness remains the second deepest Loch even when 100mm is borrowed, but the murky bottom may be disturbed, along with creatures.

That's quite a pump isn't it? Best not swim near either end. I wonder if that flow change is noticeable downstream. You wouldn't want it during storm conditions. That now partly answered by PD.

Ask thd bco. I know this is planning but they are the same authority in the Scottish process. Once upon a time you could put pegs in the corners and be photographed using a theodolite. Maybe strip the site. Nowadays they tend to want to see some construction. Eg a hole with concrete in it or a section of drain. Perhaps some services in or modified. Access as @ProDavecan be good. Choose something easyish but constructive and suggest it to the bco. They will understand. But do it or there is a genuine chance of losing the permission.

And that is surplus power to pump the loch up the mountain. Looks as if many a Ben will be turbined. This probably links with the current (I know) plan to build a new power line south, skirting the Cairngorms, from Nairnshire to the Lowlands. I've been in such a pump storage tunnel during construction. The scale is bogglingly huge. Of course it may be that the plan is to pump water up over many days of plenty, to use in extremes or whatever earns most. ie sell more cheap power at imported gas prices.

Because, perhaps, that is the implication intended by some sources with a southern readership to keep wound up. And that is population, not registered voters. That's homework for later. Don't worry, you will find the numbers to be equitable. Next consider whether a widely dispersed constituency should have slightly more representation because of more variable circumstances...by which i mean are the currently similar figures too much in favour of the concentrated urban populations? For what it's worth, I've lived in many areas of the UK. The most insular is the SE, with few having ventured north of home counties, or having any interest there. It's very common for southerners to think that Scotland can be driven through in 2 hours even with the country lanes winding through the heather. And the peoples of the Midlands feel as ignored by that there London and the powers that be, as do Scots. What was the question again?

Sorry, that was unnecessarily glib. Turbines on fields. Solar on industrial roofs and walls. Let the plants grow. There is a theoretical problem with solar on older or agricultural roofs as the additional wind load can be huge and they aren't designed for it. Perhaps Government could reduce the factor of safety, solely for solar.

That's not the same as building regs for pipe depth. There's nothing magic about 900mm either and I'd think the aerobics that far down are ineffectual. I haven't seen any science on the subject, just don't know how oxygen could replenish at depth. I suspect 900mm is an "out of harms way" statement that is preferable to silence on the subject, and tends to be practical.

Not that difficult to steer around a big column surely? Or a pylon.

Useful pics. Flashings are generally made in 3m lengths because the bending presses are made that size. In 1mm metal they are usually overlapped and it shows. In 2mm it can bd butted, with a back plate but needs pop rivets at the least. 2mm will be much the best for stiffness but is expensive and with limited colours. Even that must be fitted without twisting or the sheen will exaggerate any change. That's a great drawing. It seems optimistic to me, getting the u bends made with the right size of gap, then mastic to keep it tight. I guess you could screw inside the gutter and at the soffit. These bits don't travel well. Do you have a local fabricator? I used to have to drive about 30 miles to a cladding merchant who served mainly the agriculture industry, then drive back very slowly with these on the roof, trying to bend. If you can find one I would visit and get advice from the machine operator. They will know exactly what is possible. I still recommend battens to square it all up and avoid contact with the main faces.

There is a proposal for even more pump storage using Loch Ness. Apparently it already rises and falls 50mm. installed capacity of 1.8GW with a stored capacity of up to 36GWh, providing 20hrs of storage 1. Can a boffin advise how much energy this is, in relation to a power station / town size/ number of wind turbines or other convenient comparison? 2. Should there be a levy payable to Highland Region, for exported power?

For any CE nerds. I once had to design a surface water drain, about 300dia and 2.5m deep. It was in danger of collapsing under gte weight of thd backfill ( by digging and refilling, the interlock and load spread is lost). We filled half the depth with straw bales to reduce the dead weight and it could also float a bit.

The depths are guidelines that avoid analysis and are conservative. To the best of my understanding, the logic is thus: Q The minimum is to keep below trouble, be lower than any wheel loads will damage, and away from frost risk. None of these may apply in your situation. The max depth is to avoid the weight of trench fill crushing the pipe. If you protect the pipe and backfill very thoroughly then a bit more won't matter. Shallower is better of course, for economy and safety. Re the frost risk. What chance is there of sewage freezing? It flows briefly down the pipe and away. Workmanship is important at slow gradients to avoid lips and dips. I think at the steading, where the winter can be chilly , from -300mm cover for both foul and surface water. It wasn't questioned. Was that realism from the bco or because it was a formal design, I don't know. Another thing you can do is have open gullies and slopes, so if ever the pipe blocks, the water runs away harmlessly.

An established biggish company might have a close relationship. Small ones unlikely. You could ask an SE for a site visit and just pay for the time and a quick opinion on the likely scenario. A written report costs more of course. Then think again of the best way forward, depending on the situation. In the ideal scenario there is no structural significance, and then there will be no building regs, and the SE will write to state all that. Otherwise the builder will be guessing.

Just providing a technical solution would be enough. They probably can't though because it is a specialist skill. I've designed such flashings, hence my comments above. ie I'm saying don't use aluminium. 3 profiles is right. They are bent to order from a standard sheet colour, and then each of them is sliced to make into a corner, all by a specialist. Plus end details. Then cut a hole for the spout and seal it somehow. Anybody got any suggestions for invisible fixings? I'd love it if I'm wrong and somebody knows a way. You could think about one simpler flashing covering the large vertical, fixed on battens to remove the wobbles. Then paint or stain below. You still have the corners and ends to make and fix.

In that case, yes it does.

That applies for new build. You have constraints so the bco should give latitude.

I'd say it is possible but at huge cost. The house is almost certainly constructed from that higher level, so would need a retaining wall. Could traffic calming be the solution? 20mph is simply ignored by many, but a chicane can work. Not that the council will have the funds for it unless there is a history of accidents.

I can have a think later but immediate comment is that the timber work is too approximate. Aluminum will follow the shapes and exaggerate them with the sheen . Will this straighten? Otherwise I think batten first. will you accept visible screws?

The cheapest rwh I ever installed was a series of IBCs. 4m3 for £400 plus some plumbing. It was only for buckets of water for slunging vehicles OR could be set to dribble to slow down flow to drains and ground. Not pretty but the client loved the value.
