Not sure where to post this but I’ll try here. I’ve got a 4-run kennel I’m putting up at our new house. Each of the pens is 10’x10’ and I’m going to pour a concrete pad roughly 44’x15’. That leaves 2’ of concrete extending past each “narrow” end, a 3’ walkway in front of the “long” end to access the doors, and 2’ on the opposite “long” end or the back of the kennels. I’m planning on putting in a trench drain along that back end to rinse the pee and poo into - that will drain into a septic tank and then the waste water will run out of that and be daylighted. Does anyone have experience with a septic system like this on dog kennels? Any ideas how much fall I should have in the trench itself and then also the schedule 40 pvc that leads to the septic tank? Should I send all the drain to one end or slope each half of the kennel to the middle and run it to the septic tank from there so I can have more fall in the drain? A quarter bubble on a level works well on similar systems for people but our #2 floats and dog #2 sinks for the most part. Or is this system even the best option? Any and all info is much appreciated. I’m just tired of scooping poop every night after work and the smell of the dog pee/poop lingering around. It would be much nicer to just rinse it down a drain.
