Need Imput

Jimco, The kennels are sloped towards the building. I have a trough about 10" x 5 "deep next to the building. By the gates I have about a 2"rise sloping down to the trough. The drain is off center but the trough is also sloped towards the drain. I will have to valves at each end that shoot a stream of water down the trough to the drain. All I have to do is wash everything to the trough from the outside & the turn on the outside valves &everything gets washed to the drain. The building is also sloped to the drain & I can rinse the inside out too.
