💩 Why it's ugly
You are managing sink water, food scraps, soap, and mystery liquids behind events, mobile kitchens, and temporary worksites. Nobody applauds because the whole point is that nobody notices it.
💰 Why it prints money
Temporary kitchens, festivals, film sets, and disaster sites need compliant wastewater handling and cannot simply dump graywater. Customers pay for tanks, delivery, pickup, pumping coordination, and emergency swaps, which creates recurring multi-day rentals.
