Production and consumption of dirty water is not showing up in the production window's fluids tab

Dirty water is being consumed by filtration plants:

Dirty water (the fluid itself) does not seem to be modified by other mods:

This appears intentional, for some reason the water/dirty water used in other processes is marked as "catalyst" and therefore not counted in the production stats, presumably because it's only a byproduct?

that's right, fluid ingredients can have a catalyst_amount property that makes this many of fluids from the ingredient to not be counted in the stats,

and water in the enriched ore recipes is set up as a catalyst

Well, then it's not a bug, I guess. But what could I do to know how much dirty water is produced? I need it for base-debugging purposes. It seems like if less water would be returned to smelters after dirty water being cleaned, and I needed to set up an offshore pump to the filtering facility. I have dedicated trains for this purpose, so water shouldn't be able to get transported to other parts of the base (not that I noticed such behavior)

I just always add an offshore pump along with a top-up valve from the Flow Control mod, so if there's ever not enough water the pump will supply it, but won't oversupply. Normally it's only needed when I remove entities though and some (dirty) water is lost. A top-up valve connected to a water tank would probably also work if this event is rare enough.

I already have a pump that's limited with circuitry, but hiding the symptom might not be the best solution.
Maybe I organized my smelters or filters badly and fluid gets to where it shouldn't, or maybe it's a bug, and if so then at least I would know not to use fluid must flow (or some other feature) for non-endless fluids.
Also, My dirty water pickup is a bit complicated, because it's a double station for also dropping off clean water, so even that could be the source of the problem through some weird glitch
