HOW | From Site Water Network to Reconciled Account and Action
Water Insights™ follows five connected stages—define, record, classify, reconcile and improve—so the water account reflects the physical operation before it becomes a report.
1. Define the Boundary and Model the Water Network
The process starts with the operational facility boundary, accounting period and material water interactions. Sources, operational inputs, Other Managed Water, stores, tasks, treatment plants, internal transfers and outputs are represented as connected parts of the site water network. Site and catchment boundaries, source and destination, water quality, operational purpose and reporting period provide the context that turns an isolated flow into meaningful water information.
The MCA Water Accounting Framework recommends using site plans to identify the inputs, outputs, tasks, stores, treatment locations and catchments needed for the account. Modelling those relationships first helps expose omitted flows and prevents a corporate total from becoming detached from the physical system it is meant to represent.
2. Record and Validate the Evidence
Using Carbon Sense™, water and supporting operational data can be captured through configured integrations, scheduled imports, structured files and controlled manual submissions. Relevant evidence may include abstraction and transfer meters, SCADA records, laboratory and water-quality results, groundwater monitoring, dam and tank levels, storage surveys, rainfall, runoff and evaporation data, utility records, production information and controlled site logs.
Each record can retain its source system or file, record identifier, timestamp, original value and unit, site, asset, meter or sampling point, method, confidence and supporting evidence. Local identifiers are mapped to controlled terminology without discarding the original description.
Configured controls can identify missing readings, duplicate records, incompatible units, meter rollovers, gaps in time series, unexpected values, inconsistent periods and mismatches between connected meters or stores. Exceptions are isolated for specialist review rather than passing silently into the account. Automation focuses attention; the water professional determines whether to correct, estimate, accept or investigate the exception.
3. Classify Flows and Reconcile the Account
Validated records move into Impact Accounting™, where units, periods, boundaries, classifications, aggregation rules and balance logic are applied consistently. Flows are classified as Operational Inputs, Operational Outputs or Other Managed Water, then associated with the applicable source or destination and Water Quality Category. Measured, simulated and estimated quantities remain distinguishable, with high, medium or low confidence recorded as required.
The WAF states that measured flows and surveyed stores are preferred to simulated or estimated values unless the measured data contains a known error. Where measurement is incomplete, the method and confidence remain visible instead of an estimate being presented as equivalent to a meter reading.
For each boundary and period, the governing relationship is:
Water In = Water Out + Change in Storage
Transfer meters can be reconciled against receiving meters; opening and closing storage against recorded inflows and outflows; and site totals against invoices or other independent evidence. An imbalance is a prompt for investigation, not automatic proof of leakage. It may reveal missing metering, timing misalignment, storage uncertainty, an incorrect allocation, an incomplete flow or a genuine operational loss. Corrections and approved estimates retain their evidence and calculation history.
4. Produce WAF-Aligned and ICMM-Compatible Reporting
Through Emissions Prism™, the governed account can be transformed into the WAF outputs needed to explain both the quantity and the quality of the underlying information. These include the Input–Output Statement with disclosure notes, the Accuracy Statement showing proportions by quantification method and confidence, the Statement of Operational Efficiencies covering reuse and recycling, and contextual information about the operation and surrounding water system.
The same foundation supports the ICMM Water Reporting: Good Practice Guide. The WAF maps its flows to ICMM metrics for operational withdrawal, Other Managed Water withdrawal, total discharge, consumption and water quality, with additional context for sites in water-stressed areas.
Every reported figure remains traceable in both directions—from source evidence through classification, balance and statement, and from a reported result back to the meter, model, estimate, method and approval that created it. Reporting becomes an output of the governed water-management process rather than a separate spreadsheet reconstruction.
5. Turn the Reconciled Account into Operational Insight
Once the balance is controlled, the same dataset can be analysed by site, process, task, source, destination, asset or period. Teams can monitor withdrawals, outputs, storage movement, imbalance, reuse, recycling, water quality and intensity against production or other operational drivers.
Trend and source-level analysis helps people distinguish a real change in water performance from altered throughput, rainfall, storage, measurement or accounting treatment. They can identify abnormal consumption, recurring data gaps, unreliable estimates, transfer losses, underperforming reuse circuits or discharge issues—and choose whether the next action should be better metering, maintenance, process investigation, operational change or a stewardship initiative.
Technology carries the repetitive burden of collecting, mapping, validating, reconciling and reconstructing the account. Water specialists retain control of context and judgement, with more time to understand what the water network is showing and decide where action will deliver the greatest value.
