Kennel Septic system help needed

Make sure you have a way to pump your barrels out. even a proper working system will develop sludge in the bottom of your barrels after a period of time. eventually the sludge will reach the top of the barrels and start down the pipe to your leach field. This sludge is some nasty stuff. Remember clay does not hold much water, during the summer the water will evaporate. Take into consideration what is going to happen if you have two or three days of rain. Will your ditches fill up and back up into your grated opening into your septic system. I put in a 200 gallon tank if I remember right it took eight years before I had to pump it. Had 8 kennels 8' x 20', had 30 x 80 leach field. Plan for the worst conditions, days of rain and saturated ground conditions.
