Default Drainage Channels

I have some drawings showing 120m2 of tarmac with 1.5% fall to 3lm of 120MM wide channels connected to a 100mm pipe run of 40LM with .75% fall into culvert.

Will this be sufficient drainage ?
Client doesn't want wider channels for aesthetic reasons.

If you know the manufacturer of the channel go to their website.
Nearly all provide throughput flow for their channel.

That's not a huge area so should be more than adequate.

Either way, you are covered as its been designed by someone who's paid to check these things and you are just installing their design.
