SWA electric cable in a 10cm depth drive drain

I am getting an electric car in September and been talking to charge point installers. 

I have a 56 metre run from fuse box to garage where car would be parked. Looking at 10mm2 SWA 3-core cable on 32 amp supply. Would this be sufficient a mm2 for

length of route. 

Im burying it down to 45cm where I can except  under paths. I have a Hauraton drain on my drivr

which is 10cm deep and has metal grates on it. Was speaking to an electrician via a builder

neoghbour. Who said I could

run SWA directly in the channel by drilling into paving edges either side. So So cable would remain underground. Would concrete over anything less than 10cm down on either side and take cable down to 45cm. 

This is a picture of length which is about 6 metres.

Each side has a concrete edge on it,

so was planning to drill a 30mm hole into concrete for SWA cable and run on bottom

of plastic drain. I’d checked with installer and another electrican. But to be legal hence question before doing anything. 

Thanks

a drain is not suitable for a cable. do the job properly and stop trying to bodge it

Then are you proposing laying some of this over the top of the drain grills? https://www.tlc-direct.co.uk/Products/FMPT103.html

I trust your electrician has not agreed to run the cable in the drainage channel  ? 

This isn’t the first time this cock-eyed idea has reared its head. Gate lights or motors, drive lights, etc. The response is always the same, no way!

I find it funny.

I,have never met your electrician or builder but they do not appear to know what they are talking about?

if he thinks it's safe then let him do it and sign it off!

And he probably will, it will be for the next spark to sort.

It makes you wonder why we bother!

we sleep soundly at night because we know we have done it correctly and it's safe

They probably sleep soundly at night through ignorance

Ignorance is bliss!
