Symmetri in Water

Operational intelligence for water utilities.

Water utilities lose millions to undetected failures and reactive operations. Symmetri, Sand’s infrastructure world model platform, detects events in real time and routes prioritised actions to crews, starting with the data you have today.

See Symmetri in action in water.

A major US metropolitan water network, modelled in Symmetri. Four hundred main breaks a year, and until recently it took over four hours just to find one. Watch the pattern repeat: sense, analyze, act.
  • Sense Every pipe scored by risk, live: weather, soil, pipe age and how the network is actually plumbed together, in three dimensions.
  • Analyze A main breaks. Symmetri locates it to under 100 metres, then surfaces what matters: which customers lose water, the hospital downstream, the regulatory clock now ticking.
  • Act It drafts the response: boil-water advisory scope, valves to isolate, the crew to dispatch. One click, from the same screen.
Detection: four hours to under one. Location: five hundred metres to under a hundred. The same platform runs in production at a Tier-1 UK utility serving 16 million people, with $100M in validated benefit.

Where it sits

Between the data you already have and the decisions you need to make.

No utility has all the data. Networks are dark in places, sensors drift, records live on paper. Symmetri is built for that reality: the world model infers behaviour where the network is not monitored, and the Symmetri data marketplace and partner hardware fill the gaps that matter most.
Upstream / start with what you have

Your data, as it is

  • SCADA and PI historian, where they exist
  • GIS and asset registers, gaps included
  • Pressure sensors, AMI, work orders
  • Weather, satellite and external feeds
  • Marketplace data and partner sensors for the rest
Symmetri / decision layer for water

Sense, analyze, act

  • Real-time operational picture
  • Water network ontology
  • Infrastructure world model and consequence models
  • Optimal-action recommendations
  • Workflow embedding at a governed level of autonomy
Downstream / workflows

Actions crews can take

  • Incident dispatch and triage
  • Valve isolation guidance
  • Field-team mobilisation
  • Customer communications
  • Capital reallocation

// Symmetri does not replace these systems. It makes them act together seamlessly.

Use cases

From reactive coordination to intelligent operations.

Each use case answers a question operators ask every day, grounded in deployments at some of the world’s largest utilities. Because they share one world model, every use case you deploy makes the next one cheaper and smarter: leak detection labels the data capital planning needs, and capital planning maps the risk that fiscal planning needs.

01 / Use case

Burst detection and localisation

“Where has the network failed, and who is affected?”
ML detects bursts in under 30 minutes and localises them to within 100 metres, with freeze-thaw events predicted days ahead. Crews know where a pipe has failed and who is affected before the first customer call comes in.

02 / Use case

Network risk and non-revenue water

“Where is the network losing water, and what do we do?”
Satellite SAR triage, hydrophone arrays and flow analytics pinpoint hidden leakage without excavation. Virtual DMAs and AI-driven pressure optimisation cut leakage at source, and repairs are ranked by water recovered, not complaint volume.

03 / Use case

Asset health and capital planning

“Which assets deserve investment, and in what order?”
AI risk scoring across more than a million pipe spans replaces age-based replacement with a multi-variable deterioration model. Survival modelling projects condition forward so capital lands where it prevents the most failures.

04 / Use case

CSO and SSO prevention

“Which events put us at risk of overflow or permit breach?”
ML blockage models run across tens of thousands of sewer monitors, masking rainfall and generating risk-ranked work orders. Real-time spill alerts across treatment works, pumping stations and outfalls keep compliance ahead of the weather.

05 / Use case

Operator Assist

“What should my operators do next, and why?”
A generation of operators is retiring and decades of judgment is walking out the door. Operator Assist puts your best operator’s instincts beside every operator on every shift: what is going wrong, why, who is affected and what to do next.

Dynamic dissolved-oxygen setpoints, blower sequencing matched to live load and continuously tuned chemical dosing. A plant-wide world model of energy and emissions charts the pathway to net-zero operations.

Start where you are

Three tiers. One platform. No re-architecture.

Each tier deploys as a packaged product into your environment, meeting your network at its current level of instrumentation and data maturity, and growing from there. You do not need complete data to start; you need a place to start.

Tier 1

Dark operations

For utilities with minimal instrumentation. Intelligence from the data you already have, with no new hardware required on day one.
  • Burst detection from available data
  • Asset risk scoring
  • Incident triage

Tier 2

Noisy operations

For sensor-rich networks drowning in alarms. Correlation and consequence turn noise into a short list of what matters.
  • Sensor-rich event correlation
  • Crew dispatch optimisation
  • Isolation consequence modelling

Tier 3

Intelligent operations

For utilities ready to run proactively. Prediction and orchestration move work upstream of failure.
  • Predictive maintenance
  • Capital targeting
  • Autonomous workflow orchestration
Works on dark networks No SCADA dependency Deploys in days Your cloud or on-prem Data sovereign

Governed autonomy

Levels of Autonomy

Every recommendation runs at an explicit, auditable level of autonomy, from decision support to supervised automation. You set the level per workflow, and raise it only when the evidence earns it.
Explore autonomy levels

First step

Operational Diagnostic

Not sure which tier you are? The Operational Diagnostic benchmarks your data, instrumentation and operating model, and returns a prioritised map of where intelligence pays back first.
Take the diagnostic

Under the hood

Built on the Water Network Ontology.

Generic AI can detect anomalies. It cannot reason about consequences. Symmetri’s water use cases run on an infrastructure world model of how water actually works: the source-to-tap value chain formalised as entities, relationships and decision actions that machines can traverse.

A source-quality event forces a treatment change. A trunk-main burst affects multiple zones. A failing pressure valve leaks across a district. The ontology is what lets the platform reason about those cascades, and trade performance against cost and resilience the way your best engineers do.
