Patio drainage on new project

[markyyyyyy]

I am installing a patio and think I should install some drainage

green is where I want to install Aco drain
orange circle is where sewer is

The path edge is not level (it’s approx 3-4cm lower one side). I want to level the patio from left to right (so it will be lower than path edge one end) but slope it front to back and install an aco drain

I have a sewer/manhole right at the edge of my patio that I was possibly hoping to connect an aco drain to.

How do I go about getting through the brickwork in terms of draining the water into sewer? What pipe connects from the eco drain to drain the water?



Cheers

You can't drain surface water into a foul system. It needs draining into a soakaway

I don’t have space for a soak away….

Would a further option be to dig down another 300mm at the front edge of patio (where water will collect due to the fall on patio ) and put down 300mm of pea shingle below the compacted hardcore to help with drainage?

Or is this not suitable because the gravel won’t necessarily compact as such?

Alternatively I can install without drainage and it’ll have to naturally drain away?

It would depend on what soil type you have as to whether it would drain or not. You can dig a test pit and throw a bucket of water in to see how fast the water drains away. Alternatively, you could check where the downpipes from your guttering are draining to and possibly tap into one of those. Assuming the house is relatively modern these should already be connected to a surface water syatem of some description.
