I have a need to put a septic cleanout in the yard. The real reason is the occassional dumping of the travel trailer tanks. Spoke with the inspector. He said I could not put in a connector to dump, but he would not have a problem with a cleanout. Use it however I needed to.

So I dig down and use a snap cutter on the cast iron. Install a wye using Mission no-hub's. Should I put gravel around this before replacing the dirt? On the ground surface I intend to use one of those boxes with the lid so I will not have a problem with the mower. Have I left anything out?

Thanks for the input
