The Brew Cabin

I'm to patio an area to make a dog run. I can't leave a gravel drainage area agaianst the house wall, as the dog will eat it!

I plan to add a drain for the pation for surface water, but also to wash the dog poop into.

Do I connect a gully drain to the foul water main or the surface water main?

Dog crap = nasty = Foul water.

You must use a trapped gully, to prevent the Doggy-Doo odours wafting upwards.

I know some folk wash their pet's waste products into the SW gullies, but it's bad practice, and, if you have a chance to do it right, you might as well take it. :)
