The Rhode Island and Southeast Massachusetts distributor for Fuji Clean, selling one-tank treatment to the engineers and installers who draw septic systems for a living.
What we built
The site is a drawing set: above the grade line a photograph, below it the section, and the annotation leaders carrying down through grade from chalk into graphite.
The argument made interactive: swap a conventional treatment train for one tank on the same section, and the drain field, pump basin and floats visibly refuse to move.
Every figure is published manufacturer data, down to footprints and dry weights, because the people reading it check. Light for the trade, dark for anyone who prefers it.
