Gutter Question

[RockLobster]

I'm looking to get my driveway redone and currently doing a design. I've had one guy around here who said the downpipe going straight into the tarmac isn't ideal. He mentioned something about a gulley. I assume he would install a drain inlet hopper? One of these - https://www.wickes.co.uk/FloPlast-110mm-Square-Drain-Inlet-Hopper---Terracotta/p/432026

Is that correct? Or is it just called a gully?

I'm no expert, but sounds reasonable. Easier to carry out any maintenance if required in the future too.
Would they put a drain across the width of the drive into there too, to capture surface water.

As I understand it a hopper is just a top to the drain whereas a gulley has a trap of sorts to collect grit and so on that falls in to the drain.

A gulley would likely be a valley or channel cut into the surface to cater for the water which will lead to a drain

This is what you want.

While a gully is a channel/valley/ravine or whatever, it is also the terminology for what you are expecting to see - just it includes the u-bend bit.

Make sure you get a roddable gully - ie so you can stick a rod down it if it gets blocked

As mentioned above get the whole section including the bend to stop the smells etc, far better to have, I’ve had many a jobs cutting peoples down pipes over the years to clear out all the clogged composted leaves etc. they will no doubt run a channel across the wind of the drive to catch the rainwater I suspect depending on your situation.

I've asked them to install a ACO drain across the front of the garage. They could continue across and fit it under this drainpipe. My neighbour has this. Alternatively ACO drain up the pipe and then meet with the bottle gulley. Thanks guys I'll add to my design so they quote on that.
