Grit in sewer systems is anything not organic, sand, rocks, etc... There is a little plastic but not much in this station and it's shredded. The unit will be shaded except for the morning and that too could be fixed for constant shade.

I'm wondering about the Bio Pod lid. Is there a lid with just a round hole? I would need to fit a sock on the classifier outlet to a round pipe, probably PVC to direct the stuff into the Bio Pod automatically. It runs when the system needs it to run. Right now we have a lot of infiltration from ground water running into old collection system and storm rain infiltration. As summer progresses the flow will drop a lot and we will have less grit. Fall it will pick back up as rains come.

Some people are very curious as to the plan here. Can't wait to get going. Will start with the small one and go bigger if we need it...
