Hi I am doing some changes to my patio and i want to put french drains. My question is where shall i connect the french drains? Shall i connect them to the rainwater drain?

As you can see from the photos the lines signify where i want to put the french drains and connect both of them and then i was think to to connect them to the rainwater drain

Thanks a lot

Hi sae198417,
Provided your rainwater system drains away to an area away from the French drains you should be ok. Whether your local waterboard would give you permission to discharge land drainage into their system is another matter.
