Water and energy utilities that cut network loss they can measure.
Most utilities still find loss from a yearly audit. Aqueduct balances each district metered area every day, ranks districts by loss and checks each repair against the next week of data.
What water and energy utilities teams are up against.
Water, energy, air and operations carry equal weight. Each one runs the same loop: monitor, measure, identify, act, verify.
Water: Loss known as a yearly total
One audit figure for the whole network, with no district to send a crew to
Energy: Pumps run off their best point
Station energy read from the monthly bill, not against flow and head
Air: Treatment buildings unmonitored
Chlorine rooms and control rooms checked on a round
Operations: Rotating plant run to failure
Bearing and seal wear noticed after the pump trips
Problem, solution, impact.
How Aqueduct resolves each problem for water and energy utilities, and what changes when it does.
One audit figure for the whole network, with no district to send a crew to
A live water balance across meters and sub-meters localizes the loss, routes the fix and confirms it closed at the meter.
Loss found from the balance, not the bill, and every fix verified.
Station energy read from the monthly bill, not against flow and head
Weather-normalized baselines per building and asset show the waste in money; schedules and setpoints adjust where control is enabled.
Savings stated in money and confirmed at the meter, not estimated.
Chlorine rooms and control rooms checked on a round
Air quality per zone, overlaid with occupancy, with ventilation raised when it matters and verified back in range.
Targets held during occupied hours, with the energy cost counted.
Bearing and seal wear noticed after the pump trips
Faults diagnosed in plain language and routed into your CMMS with the fix; early signs of failure schedule maintenance first.
Fewer reactive call-outs and closures confirmed by the equipment.
One incident, from first signal to verified fix.
An illustrative example of the flywheel on a typical site.
District meters, pump stations and treatment plants read alongside SCADA and AMI.
A baseline per district, night flow and pump station.
Night flow in District 7 rising above its baseline. Loss localized to one main.
Work order routed into the CMMS with the location and recommended fix.
Night flow back to baseline. Reduction verified and retained as evidence.

Three equal ways in: keep your BMS, replace it, or build Aqueduct in at design stage.
The questions each seat asks first.
“Can you cut measurable loss alongside my SCADA?”
“Will the data stay in our environment?”
“Which pumps will fail next?”

| Rule or standard | Date | What it asks for |
|---|---|---|
| AWWA M36 water audit | Free Water Audit Software v6.1, 2025 | A standard balance of real and apparent losses |
| EPA Lead and Copper Rule Improvements | Compliance from 1 November 2027 | Lead service lines replaced within 10 years |
| State audit mandates | Texas, Georgia and others | Annual audits filed on the AWWA method; see the water loss audit page |
Loss and replacement programs share one record.
LCRI compliance begins
A decade of service line replacement runs alongside loss control, and both need an asset level record.
EU leakage thresholds
EU rules are due to set leakage targets by 2028, with national action plans to follow from 2030.

Common questions
No. Aqueduct takes a read-only feed from SCADA, AMI and the historian and never writes to them. Operators keep running valves, pumps and reservoirs from SCADA, while Aqueduct adds the district water balance, the loss ranking and the verification of each repair.
Aqueduct compares the water entering each district metered area with what customers use, every day. The gap is the loss, and a rising night flow shows which district to survey first. The non-revenue water feature then splits real from apparent losses.
Aqueduct reads SCADA tags for flow, pressure and levels, AMI and billing reads for customer use, and historian data for past periods. Pump station meters add energy per cubic meter pumped, so loss and pumping energy sit in one balance rather than in separate systems.
Aqueduct keeps the measured inputs an AWWA M36 water audit needs: system input volume, billed consumption and the gap between them, by district and month. The utility still completes and files the audit, with daily measured data instead of a once-a-year estimate.
