WOW... Thats going to be a problem. The admittance valves used on the big industrial vacuum systems really don't like trash down the drain. Plus if (well really when) the Big centrifugal vacuum blower at the holding tank
fails life gets interesting.
When I was doing some of the big casinos on the strip in vegas. I would sometimes put a big grinder called a muffin monster on the main sewer line. That thing would grind bricks or anything else going down the tubes. Sounds like the Navy
could use a few of those now and then.
