Glycol Monitoring for Airport Stormwater

Airports spray millions of litres of glycol. We watch where it goes.

Battery-powered sensors at your outfalls, streaming glycol readings to one dashboard — all winter, unattended.

See the spike tonight, not Thursday

Lab results take 1–3 days. By then the water is gone. A live reading turns a report into a response.

Cover the drains you can't walk to

Grab sampling reaches a fraction of your network. Distributed sensors watch every basin at once.

Walk into reporting season with data

A season-long, timestamped record behind your annual glycol reporting — not a handful of grabs.

The Problem

Dozens of monitoring points. Checked by hand.

This is Toronto Pearson's water monitoring map — every station sampled by walking over with a bottle, then waiting days for the lab. A ~$500K-a-year program that still can't see a spike the night it happens.

The Sensor

A small box at the drain. Hundreds of readings a day.

Electrochemical glycol sensing, automated fluidics, and a cellular uplink in one weatherproof, battery-powered enclosure — installed before the season, running unattended through April.

The Dashboard

Every outfall. One screen.

Live readings across your stormwater network, with instant alerts the moment a station crosses 100 ppm.

Built to supplement accredited lab testing — continuous visibility between compliance samples, not a replacement for them.

Deployment

Pilot-first. Winter-ready.

1

Drop in

A small pilot at your highest-priority outfalls, installed before the de-icing season.

2

Correlate

Run against your grab-sample program until the data earns your trust.

3

Scale

Cover the whole network — basin by basin, at a fraction of analyzer cost.

See your stormwater in real time.

One winter. Your grab samples as the referee.
