Smart restroom monitoring for running toilets and cleaning on demand
Restrooms are among the largest water users in a commercial building, and a running fixture can waste thousands of gallons before anyone reports it. Aqueduct combines water meters, occupancy counts and air sensors so leaks are caught early and cleaning follows use.
The busiest room in the building is usually the least measured.
What goes wrong in a restroom
- Running fixtures
A worn flapper or a stuck flush valve runs day and night, out of sight.
- Cleaning by the clock
Fixed rounds over-serve quiet restrooms and miss busy ones at peak times.
- Complaints as the sensor
Odor and supply problems surface when an occupant reports them.
Why restrooms are worth metering

Meter the risers
A meter on each restroom block shows flow per block, with a baseline for empty hours.
Count visits
Occupancy sensors count use, so water per visit and cleaning need can be compared across blocks.
Watch the air
VOC and humidity readings flag odor and ventilation problems before complaints do.
Send the right task
Flow with no visitors raises a leak alert; heavy use raises a cleaning task for that block.
What to watch per restroom block
| Metric | What it tells you | Act when |
|---|---|---|
| Flow with zero occupancy | A running fixture | Flow persists after hours. |
| Water per visit | Fixture efficiency and misuse | One block runs well above its peers. |
| Visits since last clean | Cleaning need | Visits pass your service threshold. |
| VOC level | Odor and ventilation | It stays high after a clean. |

No. Occupancy comes from people counters and motion sensors that record counts, not images, and air sensors report sound only as decibel levels. Nothing captured can identify a person. See restroom monitoring hardware.
A water meter per restroom block, occupancy sensors at the entrance and an air quality sensor for odor. Partners fit them, usually starting with the busiest rooms. See water meters.
Facilities teams get leak alerts and cleaning contractors get service tasks, each with their own alert routing. Neither needs to watch the other's alerts, and each alert names the room and time. See airport terminal operations.
Steady flow on the restroom supply while the room is empty points to a running fixture. EPA WaterSense puts a leaking toilet at 0.5 gpm at 21,600 gallons a month. See leak detection.
