The best way to deal with this problem as i had the same problem is to connect a long hose pipe from an outside tap and rig it up over the offending wall and when yea see the bas.tads urinating on yea wall give it some stick, i had a security light and a small cam riged up it was one of my favorite pass times on a saturday night great laugh try it, it is fun to watch when the drunk gets a taste of clean water over is block head.
I did similar, not with someone peeing, but had a spate of little oiks playing knock down ginger night after night, and silly little bu55ers always at the same time give or take 10 mins.
So I laid in wait behind the garden gate, with a long hose in my hand waiting for the little rascals to knock on my door.
Yup, they didnt let me down, and I let go with the water and drenched the little darlings, I laughed so much I nearly had a little accident myself.
They stopped for weeks afterwards, but then they came back, so I made a point of setting up the video camera on my window sill in the front bedroom, as I saw one of kids playing out, so I took my time setting it up so he could see what I was doing.
He must have told his mates, as I never had any bother again.
Set up a camera, develop the pics, and paste them on bus stop windows, phone boxes, on walls, lamp posts etc, word will get around that they cant take the P out of you.
