Restroom monitoring

Restroom monitoring sensors that catch running fixtures and time cleaning to use

Restroom monitoring combines an air quality sensor for odor, sound and occupancy with a compact water meter on the restroom supply. Aqueduct correlates them, so running water heard while the room is empty becomes a likely plumbing alert, odor trends set cleaning by real use, and the meter confirms the repair. No audio is recorded.

Hear the running toilet nobody reports, and clean when the room needs it.

Plumbing faults

Running fixtures caught while the restroom is empty

  • Sound plus occupancy

    Steady noise with no one present separates a stuck flush valve from normal use.

  • Flow confirms it

    The restroom meter shows continuous flow, so the alert carries both the sound and the water evidence.

  • Ticket with evidence

    Aqueduct routes the fault into your CMMS with the restroom, the trace and a recommended check.

Cleaning by use

Cleaning rounds set by odor and occupancy, not the clock

  • Odor trends

    H2S and methane levels show which restrooms need attention and which can wait.

  • Occupancy counts

    PIR occupancy shows how heavily each restroom is used across the day and week.

  • Cleaning recognized

    Short VOC peaks confirm a clean happened, and persistent ones flag a ventilation issue.

Proof of repair

The meter confirms the fixture stopped running

  • Flow back to normal

    After a repair, restroom flow returns to its usual pattern and stays there.

  • Water saved, measured

    Reduced flow is compared against the expected baseline, so water saved is measured rather than guessed.

  • Privacy kept

    No audio and no cameras, only decibel levels, air readings and water volume.

Old way vs the Aqueduct way

Restroom upkeep, before and after Aqueduct

The old way
  • A running toilet runs until someone complains.
  • Cleaners follow fixed rounds whether rooms were used or not.
  • Odor complaints are the only air quality signal.
  • The water bill hides which restroom is wasting water.
  • Repairs are closed without checking the flow stopped.
The Aqueduct way
  • Sound and flow in an empty room raise an alert.
  • Odor and occupancy set when each restroom gets cleaned.
  • Odor, VOC and ventilation trends are measured continuously.
  • A restroom meter shows exactly where the water goes.
  • The meter confirms the fixture stopped running after repair.

Two devices, read together.

Four signals, one restroom

Odor

H2S and methane trends show when cleaning is due, when ventilation is weak or when plumbing is starting to fail.

Sound

Minimum, maximum and average decibels, never audio. A steady level can reveal a running toilet or leaking flush valve.

Occupancy

PIR shows whether anyone is in the room, so running water in an empty restroom stands out.

Water use

A meter on a sink supply or the restroom main shows excessive or unexpected flow and confirms repairs.

How it works

How the signals combine

01

Running fixture

Continuous sound and steady water flow with no occupancy points to a stuck flush valve or failed fixture.

02

Cleaning event

A short VOC peak that fades as the room ventilates is normal cleaning. A persistent one suggests a ventilation problem or an ongoing source.

03

Cleaning by use

Odor trends and occupancy counts move cleaning from fixed rounds to the times the restroom actually needs it.

04

Repair verified

After a fix, flow returns to its normal pattern on the meter, so the repair is confirmed, not assumed.

Questions

Common questions

Aqueduct pairs a bathroom monitor air quality sensor, which measures odor, VOC, sound and PIR occupancy, with a compact water meter on the restroom supply. The combination tells plumbing faults apart from normal use.

Yes, indirectly. A steady sound level and continuous water flow while PIR shows the room is empty points to a running toilet or leaking flush valve, and Aqueduct raises an alert.

No. Sound sensors report only minimum, maximum and average decibel levels per interval. Nothing is recorded or stored as audio, which protects occupant privacy.

Odor trends and occupancy show when each restroom actually needs attention, so cleaning moves from fixed rounds to real use. Aqueduct can route the request into your CMMS.

Compact meters are typically 1/2 inch to 1 inch, fitted on an individual sink supply or on the main line serving the whole restroom. The exact meter is chosen per site.

Disinfectants and deodorizers release VOCs as they evaporate, so cleaning creates short peaks. Aqueduct looks at size and duration to tell normal cleaning from a persistent source or poor ventilation.
