Evidence-driven water solutions

Virridy bridges the gap between real-time environmental monitoring and sustainable development finance. Our IoT sensor technology powers both continuous water quality surveillance and the verified impact measurement behind our carbon credit programs.

Real-Time Monitoring

Continuous, in-situ water quality data replaces costly, delayed lab sampling with thousands of measurements per deployment.

Machine Learning

ML analytics fuse sensor networks, remote sensing, and hydrological data to quantify contamination and verify outcomes.

Peer-Reviewed Science

39 peer-reviewed publications and multi-site field validation provide the evidence base behind every deployment and credit.

Global Scale

Operating across 9 countries with programs spanning drinking water, agriculture, and watershed restoration.

Two innovations. One mission.

Explore our sensor technology platform or our carbon-financed clean water programs.

Sensor Technology

Lume — Water Quality Sensing

Continuous water quality monitoring — for the cost of a single grab sample.

The first single-unit fluorimetric sensor for continuous microbial contamination monitoring. Three measurement modes — TLF for E. coli, Chlorophyll-a for algae, FDOM for dissolved organics — with integrated power, cellular/satellite connectivity, and 1-year battery life.

Carbon Finance

Water for Carbon

Clean Water. Carbon Credits. Proven Impact.

We design and scale drinking water treatment, precision irrigation, and watershed restoration programs. IoT sensors and scientific rigor verify emissions reductions and generate carbon credits that sustain clean water services for communities that need them most.
