Fontus Blue

Fontus Blue is a water optimization platform built for drinking water utilities. We help teams optimize water quality, manage chemical costs, and reduce guesswork, by replacing trial-and-error with confident, data-driven decisions. Our platform combines Virtual Sensors, Virtual Jar tools, and expert coaching to help utilities simulate, validate, and optimize treatment before it goes live. Operators can move faster, reduce manual sampling, and access insights that scale beyond what's in a single operator’s head. Whether you’re tackling turbidity, DBPs, corrosion, softening, or harmful algal blooms, we’re here to support your team with tools built for operators and designed for optimization. Stop guessing. Start predicting.
