How to dispose of thick dirty vacuum water without clogging the sink

Emptying dirty water from a wet vacuum into a sink or trash bin risks clogs and messes because the reservoir contains thick debris. Pouring it improperly can also lead to plumbing backups or plumbing contamination issues. The safest approach is straining out solid waste for the trash before discarding the liquid safely.

where do you empty the dirty water reservoir? It’s basically vacuum dirt soup, so I’m not keen on pouring it into the sink OR the bin.source ↗
