Airports where every meter point reports, and every loss gets fixed.
Terminals, concourses, cargo and landside on one platform. Thousands of meter points become a live balance, and an anomaly becomes a ticket and a verified saving.
Thousands of meter points become one live balance, and every loss gets an address.
Terminal, tenant and airfield water reconciled every minute
- One live balance
Main supply is reconciled against terminals, tenants, cooling and airfield use, with telemetry refreshed every 60 seconds.
- Loss with a location
Unaccounted water is localized to a riser or a zone, so the crew walks to one place, not everywhere.
- Proven at scale
Water savings are verified at the meter against a weather-normalized baseline. Every loss is read from one live balance.
Peaks that follow the flight schedule, not the clock
- Weather and schedule baselines
Baggage halls, chillers and jet bridges are baselined against weather and the flight schedule, not a flat average.
- Peaks shifted
Where control is enabled, with owner approval, loads are sequenced so peaks drop, and every command is logged.
- Concourse air
Fresh air follows passenger occupancy by zone, and the energy cost of that air is counted alongside it.
Concessions billed on what they actually used
- Sub-meters reconciled
Tenant sub-meters reconcile to the main meter, so gaps between billed and metered use show up quickly.
- Bills validated
Utility bills are checked against metered use, so overcharges and estimated reads are caught before payment.
- Records for disputes
Concession charges rest on measured interval data, so a tenant query is answered with a chart, not a debate.
Running an airport, before and after Aqueduct
- The quarterly water bill is the first sign of a leak.
- Thousands of meters report into systems nobody reconciles.
- Chillers run the same profile on quiet days and peak days.
- Tenant water charges are estimated from floor area.
- A leak ticket closes when the crew says it is fixed.
The Aqueduct way- The live water balance flags the loss within days, with an address.
- Every meter point reconciles into one balance for the whole airport.
- Plant follows the flight schedule, and peaks are shifted with approval.
- Tenant charges rest on reconciled sub-meter data.
- A leak ticket closes when the balance confirms the loss stopped.
What airports teams are up against.
Water, energy, air and operations carry equal weight. Each one runs the same loop: monitor, measure, identify, act, verify.

Where teams put it to work
A riser, not a hunt
Anomalies arrive as tickets in the airport CMMS with the likely riser and the recommended fix, then close only when the balance confirms it.

One airport, six teams that need the same numbers
Airports split responsibility across departments that rarely share data. A single measured record gives each team what it needs without a separate project.
Facilities and engineering
The team keeps plant running across terminals built in different decades, often with different BMS vendors. Aqueduct reads them side by side.
- One view across mixed BMS generations
- Faults routed into the CMMS with the likely cause
- Plant drift ranked so capital goes where it pays
- Measured
- plant energy, flows, zone conditions
- Target
- design performance per system
- Aqueduct
- fault detection, diagnosis and verified closure
Sustainability and carbon
Carbon accreditation and annual reporting need scope 1 and 2 numbers that trace to a meter. Aqueduct supplies measured use per terminal and per fuel.
- Electricity, gas and diesel per terminal and system
- Weather-normalized trends for year on year claims
- Exports for the carbon footprint and reduction plan
- Measured
- energy by fuel, by building
- Target
- the airport's reduction targets
- Aqueduct
- supplies the evidence, the accreditation body assesses it
Commercial and concessions
Concession utility charges based on floor area leave the airport exposed. Measured tenant use makes the charge defensible.
- Tenant sub-meters reconciled to the main
- Interval data behind every charge
- Disputes answered with a chart
- Measured
- tenant electricity and water
- Target
- full recovery of tenant use
- Aqueduct
- exports measured use to your billing system
Airport operations center
The operations center needs to know when a utility problem will affect passengers. Aqueduct raises alerts by location and severity, without touching operational systems.
- Alerts for restrooms, gates and concourses by location
- Conditions in passenger areas visible live
- Airport operational systems stay separate
- Measured
- zone air, water and power events
- Target
- no passenger-facing failures
- Aqueduct
- location-based alerts with a ticket attached
Finance
Utility bills for a large airport are complex, with many accounts and tariffs. Bills are checked against metered use before payment.
- Bills validated against meters
- Savings stated in money through rate configuration
- Budget forecasts on weather-normalized use
- Measured
- utility consumption and demand
- Target
- pay only for what was used
- Aqueduct
- bill validation and verified savings
Tenants and airlines
Airlines and concessionaires increasingly ask for their own use data. A shared measured record means one set of numbers for everyone.
- Tenant level reports on request
- Same data the airport bills from
- Supports tenant sustainability reporting
- Measured
- tenant sub-meters
- Target
- one agreed number
- Aqueduct
- shares the record the airport chooses to share
What each Airport Carbon Accreditation level asks of your data
Accreditation is assessed by the program and its verifiers. Aqueduct supplies measured energy evidence; it does not accredit anyone.
| Level | Focus | What measured data supports |
|---|---|---|
| 1 Mapping | A carbon footprint for emissions the airport controls | Scope 1 and 2 energy use by fuel and building, traced to meters |
| 2 Reduction | Targets and shown reductions against them | Weather-normalized trends that separate real reduction from a mild year |
| 3 Optimization | Engaging airlines, tenants and service providers | Tenant and concession use measured and shared |
| 3+ Neutrality | Offsetting residual scope 1 and 2 emissions | A defensible residual, based on measured use rather than estimates |
| 4 and 4+ Transformation and Transition | Absolute reductions aligned with climate goals | System level evidence for where reductions came from, verified at the meter |
| 5 | Net zero for emissions the airport controls | Continuous measured record to show the position holds year on year |
Terminal by terminal, without disrupting the airfield
Airports cannot shut a concourse to install meters. The rollout follows access windows and starts where existing meters already report.
Read what already exists
Connect to the BMS, existing utility meters and any historian. Most airports have thousands of points that report into systems nobody reconciles.
First balance and baselines
A water balance and energy baseline per terminal, normalized for weather and, where a schedule feed is available, for flight activity. The first losses usually appear here.
Fill the gaps
Add sub-meters and air sensors where the balance does not close, installed with Atria during night access windows. Wireless devices avoid new cable routes airside.
Act and verify
Findings routed to the CMMS, tenant billing on measured use, and where control is enabled, with owner approval, schedules applied to gates, garages and AHUs.
Extend and report
Further terminals, cargo and landside added on the same model. Carbon and water reporting runs from the measured record.
Keep, replace or build in
Keep
Older terminals keep their BMS and meters. Aqueduct reads them over BACnet, Modbus and vendor APIs and puts them on the same model as newer buildings.
Learn moreReplace
Where meters or controls have failed, Aqueduct supplies replacements and brings them online with the rest.
Learn moreBuild in
New terminals and expansions specify the measurement layer at design, so the building starts with a baseline.
Learn moreVerify
Every saving is verified at the meter against a weather-normalized baseline, then stated in money through rate configuration.

Common questions
When the balance stops closing, the loss is flagged with a location, instead of waiting for the bill. Every saving is verified at the meter against a weather-normalized baseline.
Yes. Keep, replace or build in: Aqueduct works with what is installed, replaces what is failing, or is specified into a new terminal.
It supplies the measured use per tenant and exports it. Your billing system issues the bills.
Instead of relying on a site-wide quiet period, Aqueduct keeps balances per terminal and riser and compares each with its own baseline for the same time and traffic. A riser whose low point keeps rising stands out even while the terminal is busy.
Yes, where the airport provides a schedule feed. It is used to explain load and to normalize baselines. Aqueduct does not write to airport operational systems.
Installs follow the airport's access and escort rules, usually in night windows. Wireless LoRaWAN devices and clip-on meters reduce the need for new cable routes, and Atria confirms each device is reporting before the crew leaves.
Where those supplies are metered, yes. They become named terms in the terminal water balance, so they are not confused with loss.
It supplies measured scope 1 and 2 energy data by fuel and building, and weather-normalized trends. Accreditation itself is assessed by the program and its verifiers.
