@BowsacNoodle I was wondering how he was handling all the soap, etc., and what you pointed out makes sense.

The only part I had time to read during my bathroom break was the canister filter (prefilter?) notes in the "manual", and he said he recommended change every 150 showers, which would be about every month for my family of 4.

I could see this system being most valuable prepacked with a water tank in a shipping container for remote construction sites, or other areas where rainwater collection isn't viable. It would also be really good as an RV conversion.

There is a company that pioneered containerized wasterwater treatment, and my understanding is that remote construction was a primary part of their business.
