For parents and teachers
- How a real wastewater plant works, one block at a time: screens, grit, settling tanks, the air eaters and ammonia changers, the clarifier, UV light, the sludge line (digester, turbine, squeezer, compost, oven), later the carbon filter and the emergency tank. Real US sizes and prices; every number has a source listed in the design notes.
- Three stages over 15 days: a normal town, then strong water and new rules, then hidden harms (grease, medicines, tiny plastics, a spill, flu) and what they do to the farms and the sea. The polluter pays. A Theater shows every pollutant and how to "send it home right"; a Waterpedia holds 59 short stories.
- Aquabot, the auto control master, runs the machines and explains what, why and for whom. The clock waits while a child reads.
- Read-aloud is off at the start so a classroom stays quiet; the Voice button turns it on and uses the device's own voices.
- Progress saves itself on this device. Clearing the browser's site data erases it.
- Crayon or Movie look: the switch at the top of this site sets the default; the title screen and Menu inside can change it any time.
