White pipe (flexible) in drainage brown pipe is dripping water slowly outside house

I have recently noticed water dripping inside a short rain water down pipe even on non rainy days outside the house entrance. The short down pipe is located outside downstairs WC. I took off the down pipe which is directly connected to the rain water drain and found that there is a short white pipe (possibly 5-10mm) inside that that is dripping water continuously. The boiler is at the back of the house so its not a condensate pipe. There is no AC in the house. Does anyone have any ideas of what this could be? Thanks
