Domestic sewage treatment using vermifilters. Primary, secondary and tertiary treatment of blackwater and greywater to a very high level suitable for surface...
I’m always hesitant on these systems without water testing “certificates”. Removing turbidity and removing bacteria is a different kettle, one is invisible and far more dangerous.
That said, there is plenty of evidence that worms do break down viruses and bacteria so potentially the system is safe to do surface water. I wouldn’t be playing, drinking, or eating root crops from it, but it’s definitely better than shitting straight into a creek.
Even my greywater treatment got worms into it and they are thriving. This is a biochar/plant/worm system so 3x the cleaning power? I don’t know, I can just make up wild claims on the internet. Good enough to drink! Trust me!

We have some worm farm systems here in Aus but they need to be approved by the Local/State Government (Victorian certs: https://www.epa.vic.gov.au/for-community/environmental-information/water/about-wastewater/onsite-wastewater-systems) you reside in. A couple of examples:
