Sorry, not uksuds.com, actually (believe it or not) 'freeflush' ( https://www.freeflush.co.uk/products/suds-attenuation-sizing-design ). Cost is £120 now. The calc looks something like this (I think they have updated it now). The key output number is the 'tank size' (the 95% is assuming a tank made from typical crates which are 95% void / 5% plastic). The 'tank' can be any shape, of course. The key inputs are your location, the allowed drainage rate (1.9 l/s in my case), the horizontal area of your roof and any 'non-permeable surfacing' e.g. concrete driveway. Actually, for a quick and dirty calc (as we're in a similar location weather-wise) just pro-rate my numbers using your own roof area etc.

What’s the fall between ground level at the house and invert level at the pipe? Suggest you need about 1 in 100 on the pipe plus about 20cm for rainwater gullies. Maybe get a suds analysis (uksuds.com) as the 1 l/s thing is a suds requirement. That calc uses your roof area and any non-permeable hard standing (so plan to have a permeable driveway), weather data, allowed drainage rate (2 l/s in your case), some climate assumptions and a bunch of stats to figure out the tank size you need. If you have the fall and room (under the drive maybe) you can use a suds tank. If not, above ground storage like butts. It’s possible your ground even in winter maybe take some water too. Storage can be an actual tank, crates, dug hole with shingle in (at 30% volume) etc. I’m using a permeable drive as part of the ‘tank’. Any place to drain at the rear of the plot too?

Very good, extra brownie points for bank holiday working 😀.

For french drains / perforated drainage pipes in clay - would you geotextile (and have this possibly silt up) or not (and have the drain possibly silt up)? A quandry / puzzle / dilemma?

Count me in

1400mm stone? That is, 1.4m diameter boulders This is under suspension bridge piers?

Nice work:) Mm accuracy in building work is impressive. Care to share a few tips?

Suggest this is the time to go full beans: Hassle the planners for more info. What did the consultees say? Hassle the architects to bug their contacts and ask them to talk at the meeting. If there’s any doubt, pull in the cnsultants too. Otherwise you might be looking at a planning strike against you and, maybe, 1-2 years delay. I’ve done that and it’s no fun and a complete waste of time and resources.

Also ... + how do people generally seal the ends of ,say, an armoured cable in a 63mm duct?

Also, where there's several power lines that run parallel for a bit - do they need 100mm separation too?

Coupla questions I couldn't find an answer for: + can I run a MDPE water pipe below a 110mm rainwater drainage pipe in the same trench? I plan to put a bunch of power / network stuff above that lot too (in their own ducts). For instance, Essex & Suffolk Water has the diagram below, but doesn't show drainage pipes. + when I cross an open ditch do I need to be way below the bottom of it (UKPN docs suggest 1m) as though it was level ground? Simiarly under a piped culvert?

Ah, to report back - I was recomended a QS as a way to solve the 'am I getting a reasonable price' problem. That's where there were few apparent takers for the job. That worked a treat. The QS thought the bid from the single contractor was fair.

I think you'll struggle to get qualified because of the apprentice / proof of work accomplished element. There is an episode, I think, of Artisan Electrics where one of their clients got qualified - so it's not impossible. As an ex-EE consultant, I would love to find a way too. You might be able to do a deal with a sparky where you do all the dumb and time consuming cable pulling & practical installation work and they do the 'intelligent' work - wiring up, testing etc.

Thurs 8th maybe?

@Gus Potter - as Buildhub royalty, I'm sure we would convene an appropriate celebration if you visited our conrner of the world. A little short of the Pope's funeral, but not by much .

Thanks, that sounds like hard-won info. Nothing like a few inflexible and capricious tax rules to screw everything up, huh?

Rated people and about £99 should cover it - but the money is made from fixing the faults.

Feel free to carry on without me - sun’s out, kettle’s hot etc. @lsb - sorry to hear about your mishap, there’s always something,..

Duh, I just discovered that the better 1/2 has booked us to see Dara O'Brien next Thurs, so I will have to miss which is a great pity. I like the idea of visiting someone's site and local though. Mine's a (part) driveway and nothing else much atm .

Does the Kubota red key thing not work? You can get a keypad fitted that needs a PIN entered for £300.

Morning. Anyone with a raft have an example cost? @marshian ?

Congrats

Great that you got a much speeded up start letter. Curious though. The take from my own appeals is that both the LPA and the Inspector largely make it up as they go along. Is this one a different inspector? - I noticed that they seem to end up with quite different pass and fail stats.

What kind of duct sizes are people using?

>>> Their sheds are good as sheds. Yeah, +1.
