Hi, I am trying to figure out the best drainage scheme for a tricky patio shape prior to paving.

Last summer, we excavated 2 feet down to form a sunken patio area. The patio is surrounded by 2 foot high brick walls to create raised beds. The shape is essentially two separate patios. One is a 4.5m dia. circle and the other is a 4.5m wide/deep square. Both patios are linked by a 3m long walkway.
Hard to describe, is it possible to send an image through?

During excavation we also dug out a 1m deep "sump" in the middle of the "square" patio and filled it with rock so all water will end up there. Hoping to get some suggestions as to the best place to locate the actual grilles to take the water away from the paving surface. I will use 100mm pipe to get water from the grilles to the sump and I think I probably need two drainage points. Would even consider linear drains if necessary.

There's a help file for posting images - click the Help button at the top right corner of the page. Alternatively, email images to me and I'll upload them for you.

Is this "sump" you mention supposed to be a soakaway? Have you read the main website?

Tony,

Couldn't find anything in the help file so I have sent 3 photos to your ******* & ******** addresses. The photos should clear it up.

I expect the answer is simple enough but I can't seem to find it so any pointers would be useful. I want to avoid putting drains in the middle of each patio if possible as I think it would make the falls hard to achieve when I do the paving, so would prefer to drain to perimeter point(s) somewhere along the retaining walls.

And you are correct, I meant to say "soakaway" instead of "sump". I plan to test it before paving by running hose for a few hours and seeing what happens.

Holy Cow, what was I thinking! Please accept my apologies Tony.

I really couldn't find anything in the help file about sending pictures so I thought I would use the direct email addresses I found on your website(s). I realise now I should NOT have stated what the email addresses were in this forum due to problems with harvesters collecting email addresses, etc.

I guess I've blown any chance of advice on drainage now?
