I have a slab with a drain. I built the kennels up and just wash everything down. Spray the dogs off at the same time. Seemed like something I would be proud of. Never felt like a waste of money. Besides the dude asked.
I was not trying to be rude. Sorry it came out that way.
I am going to use wood off the ground and put a rain gutter on the back and have it go to a pipe and into the sewer. I was going to make a small septic system but the sewer is where poop goes and I just had pipes replaced and had a seperate access put in I can run over to
Everyone has a different situation. I just like cheap and easy because I am a broke, lazy dude
