AI‑powered SaaS turns fragmented hydrological signals into a governed, real‑time operating system for utilities, agriculture, and basin authorities. The durable loop is retrieve → reason → simulate → apply → observe: ingest permissioned telemetry (stream gauges, reservoirs, SCADA, smart meters, soil moisture, weather/satellite), use calibrated models for demand forecasting, leak/burst detection, water quality, irrigation optimization, and flood/drought risk; simulate trade‑offs (supply, equity, energy, ecology); then execute only typed, policy‑checked actions—valve setpoints, pump schedules, pressure zoning, release/abstraction plans, irrigation allotments, conservation notices—with preview, approvals, idempotency, and rollback. Programs run to explicit SLOs (alert latency, forecast error, action validity), enforce privacy/residency and water rights, and track cost per successful action (CPSA) as losses fall and reliability improves.
Trusted data foundation (governed)
- Hydrology and infrastructure
- River/stage/flow gauges, reservoir levels, groundwater wells, canal telemetry, SCADA (pumps/valves), pressure/DMAs, burst alarms, asset health.
- Demand and usage
- Smart meters (AMR/AMI), consumption by DMA/sector, seasonal/weekday patterns, tourism/industry loads, conservation stages.
- Weather and remote sensing
- Radar/nowcast, gridded forecasts, EO imagery (snowpack, surface water, NDVI), soil moisture, evapotranspiration (ET).
- Water quality
- Turbidity, residual chlorine, conductivity, temperature, pH, contaminants; upstream discharge reports.
- Policy and rights
- Allocations/permits, environmental flow requirements, drought/flood plans, tariff structures, energy prices, carbon targets.
- Governance metadata
- Timestamps, device IDs, jurisdictions; ACL‑aware retrieval; region pinning/private inference; “no training on customer data” defaults.
Abstain on stale/conflicting inputs; every decision brief shows sources, times, and model versions.
Core AI models that move outcomes
- Demand and loss forecasting
- Short‑ to long‑horizon forecasts with weather/holiday effects; non‑revenue water (NRW) and diurnal signatures at DMA scale.
- Leak and burst detection
- Pressure/flow anomalies, nightline analysis, transient events; rank likelihood and locate via hydraulic fingerprints.
- Pumping and energy optimization
- Schedules to meet head/flow at lowest TOU energy cost; reservoir/pipeline constraints; GHG targets.
- Reservoir and release planning
- Inflow forecasts (snowmelt/rain‑runoff), rule curves, flood control vs storage trade‑offs; ecological and downstream demand constraints.
- Irrigation and allocation optimization
- ETc and soil‑water balance; fair allotments by crop/zone; canal scheduling and rotation; conveyance loss estimates.
- Water quality anomaly detection
- Early warning on turbidity/chlorine drifts and contamination plumes; safe flushing/isolation plans.
- Flood and drought risk
- Nowcast to seasonal indices; compound risk (rain‑on‑snow, saturated soils); urban pluvial and riverine inundation mapping.
- Quality estimation
- Confidence per case; abstain on thin/erratic sensors; request calibration or redundancy.
All models expose reasons and uncertainty; evaluated by DMA/basin/season to manage bias and drift.
From signal to governed action: retrieve → reason → simulate → apply → observe
- Retrieve (ground)
- Assemble hydrology, infrastructure, demand, weather/EO, quality, and policy with timestamps/versions; reconcile conflicts; banner staleness.
- Reason (models)
- Forecast demand/inflows, detect leaks/quality issues, optimize pumps/allocations, compute flood/drought risk; draft remediations with reasons and uncertainty.
- Simulate (before write)
- Project supply reliability, NRW reduction, energy/GHG, equity across users, ecological flows, flood volumes, and rollback risk; show counterfactuals.
- Apply (typed tool‑calls only)
- Execute via JSON‑schema actions with water‑rights, safety, and change‑control gates; idempotency keys; rollback tokens; receipts.
- Observe (close the loop)
- Decision logs link evidence → models → policy → simulation → actions → outcomes; weekly “what changed” tunes thresholds and rules.
Typed tool‑calls for water ops (safe execution)
- set_valve_position(asset_id, position%, change_window, safety_checks)
- schedule_pump(asset_id, start, duration, target_head|flow, TOU_constraints)
- isolate_dma_for_investigation(dma_id, valves[], ttl, reason_code)
- issue_conservation_notice(zone_id, stage{voluntary|mandatory}, measures[], locales[])
- update_release_plan(reservoir_id, schedule[], min_env_flow, flood_rule, approvals[])
- allocate_irrigation_quota(scheme_id, zones[], volumes, rotation, fairness_rules)
- flush_or_chlorinate(main_id, plan_ref, sampling_points[], safety_checks)
- open_incident(case_id?, category{leak|quality|flood}, severity, evidence_refs[])
- publish_public_notice(audience, summary_ref, channels[], accessibility_checks)
Each action validates permissions; enforces policy‑as‑code (water rights, safety, environmental flows, quiet hours, residency); provides read‑backs and simulation previews; emits idempotency/rollback and an audit receipt.
Policy‑as‑code: rights, safety, and equity
- Water rights and allocations
- Permit limits, priority classes, environmental flows, indigenous/community rights; drought stages and exemptions.
- Safety and quality
- Chlorination and flushing SOPs; boil‑water advisories; discharge permits; confined‑space and switching procedures.
- Change control
- Approval matrices, maintenance windows, canary adjustments, rollback; incident‑aware suppression.
- Privacy and residency
- Smart‑meter data minimization, aggregation for public dashboards, region pinning, short retention.
- Equity and accessibility
- Fairness in conservation/allocations; accessible notices (language, literacy, disability); tariff assistance triggers.
Fail closed on violations; suggest safe alternatives (e.g., advisory vs isolation; staged releases).

- Promotion policy
- Assist → one‑click Apply/Undo (pump schedules, advisories) → unattended micro‑actions (minor pump/valve tweaks) after 4–6 weeks of stable precision and audited rollbacks.
Observability and audit
- End‑to‑end traces: sensor hashes, model/policy versions, simulations, actions, approvals, outcomes.
- Receipts: setpoints, releases, advisories with timestamps, jurisdictions, safety/rights checks.
- Dashboards: NRW and leak MTTR, supply reliability, energy/GHG, flood/drought incidents avoided, water‑quality compliance, equity metrics, CPSA trend.
FinOps and cost control
- Small‑first routing
- Lightweight anomaly/forecasting for most tasks; run heavy hydraulics/EO only when needed.
- Caching & dedupe
- Cache features, EO tiles, sim results; dedupe identical alerts by scope/time; pre‑warm hot DMAs/basins.
- Budgets & caps
- Caps on simulations/hour, advisories/day, valve ops; 60/80/100% alerts; degrade to draft‑only on breach.
- Variant hygiene
- Limit model/rule variants; golden sets/shadow runs; retire laggards; track spend per 1k actions.
- North‑star
- CPSA—cost per successful, policy‑compliant water action (e.g., leak isolated, safe release, quota allocated)—declining while reliability and equity improve.
90‑day rollout plan
- Weeks 1–2: Foundations
- Connect SCADA/gauges/meters, weather/EO, quality labs; import policies (rights, env flows, safety). Define actions (set_valve_position, schedule_pump, isolate_dma_for_investigation, update_release_plan, allocate_irrigation_quota, flush_or_chlorinate). Enable decision logs; set SLOs/budgets.
