How to add patio drainage?

[Sched7]

I've just installed a concrete patio and after a heavy downfall the rain has highlighted where I need to place some drainage.

Based on the attached pic, I was wondering what the easiest solution would be to draining the water from the patio. I was thinking of digging down near the downpipe and adding a junction to the downpipe as well as a shallow drain placed next to the downpipe - this would allow both water from the gutters and patio run-off to flow to the stormwater.

Another solution may be to cut the downpipe and add an open grille drain below the downpipe and just allow any run-off from the patio to drain away too.

Any advice would be much appreciated.

Hi @EricL,

That is a really good call on your part, regarding the Council approval, I'd completely forgotten about that.

Over here, I believe you only have to have approval where you are increasing the size of any storm-water capacity into their system.

But yes, I have no idea how that works in Australia and I would hate to give the wrong advice.

Especially with Councils, you don't want to be "found wanting" if they start asking questions, get their advice first.

Cheers,

Mike T.
