2. System Purpose & Scope

The Cyprus Water Intelligence (CWI) system is a production-grade, multi-tier software platform designed to convert raw public water resource metrics in Cyprus into operational decision intelligence. The system aggregates real-time reservoir levels, historical inflow climatology, weather metrics, satellite imagery, and simulated night-flow distribution network telemetry. Using these data points, CWI:

Computes deterministic water scarcity and drought risk scores at national and district levels.
Projects reservoir levels over a 90-day horizon using seasonal climatology models.
Flags geographical areas with potential water distribution network leakage.
Visualizes reservoir water surface area using Copernicus Sentinel-2 satellite data.
Simulates water-conservation policy levers and price-elasticity responses for luxury water use.
Schedules daily desalination plant production using a renewable-energy-aligned merit-order optimizer.
Generates structured narrative weekly water briefings.

The system is designed to provide utility operators and public administrators with a single, explainable pane of glass for drought resilience, infrastructure triage, and emergency resource management.

3. Cyprus Water Scarcity Context & Operational Mandates

Every threshold, coefficient, and algorithm in the CWI codebase is tailored to address specific, critical parameters of the water crisis in Cyprus:

Critical Reservoir Drawdowns: In early 2026, Cyprus reservoir levels dropped to roughly 13.7% of total active capacity, recovering to only ~21% by spring. CWI maps this baseline to trigger emergency actions at strict storage stress boundaries.
Structural Supply Deficits: Cyprus faces a projected annual water deficit of approximately 14 million m³ under average rainfall patterns. This structural deficit dictates our scenario-simulation parameters.
Severe Distribution Losses: In several local networks, non-revenue water (NRW) losses due to leakage reach 40%. Fixing existing leaks is the most cost-effective way to recover water. CWI elevates leak-detection metrics to a top-level alert category, prioritizing them over building new supply capacity.
Unbalanced Tourism-Driven Consumption: Tourism areas consume up to 500 liters per person per day, compared to an EU average of 120 liters. CWI implements tourism factor scaling in its forecasting models and applies price elasticity models specifically to hotels, resorts, and private swimming pools.
Energy-Intensive Supply Mix: Over 70% of drinking water in Cyprus is produced via seawater reverse osmosis (SWRO) desalination. This process is projected to consume 12% of the national electricity grid load by 2030 (approximately 700 GWh), relying heavily on carbon-intensive grid fuel. CWI includes a green desalination scheduler to match plant production hours with peak solar and wind generation, lowering operating costs and grid emissions.
Underutilized Recycled Wastewater: Approximately 4 million m³ of treated wastewater is discharged to the sea annually. CWI integrates recycled water routing into its scenario planning to encourage agricultural substitution.

4. The Strategic Inverted Blueprint Architecture

CWI adapts the structural design of the open-source H2O.ai / NVIDIA Flood Intelligence Agent. The flood blueprint uses a multi-agent structure to respond to excessive water events. CWI inverts this problem space to address water scarcity:

Upstream Flood Blueprint Agent	CWI Scarcity System Equivalent
Data Collector	Aggregates reservoir storage, meteorological feeds, satellite NDWI, wind/solar metrics, and night-flow telemetry.
Risk Analyzer	Evaluates storage stress, year-on-year storage declines, leakage indicators, demand pressures, and inflow rates.
Predictor	Projects reservoir volumes via climatology, forecasts tourist-driven demand, and optimizes desalination schedules.
Emergency Responder	Formulates action recommendations (e.g., dispatching repair crews, enacting restrictions, routing recycled water).
AI Assistant	Assembles raw metrics into narrative, director-ready weekly briefings.

Maintaining this alignment allows CWI to leverage established software patterns, keep APIs compatible, and use standard inference interfaces.

5. The Four Cooperating Runtimes

To achieve operational stability, security, and high performance, the system is split into four decoupled runtimes:

5.1 Intelligence Core (FastAPI Backend)

Role: The single source of truth for business logic, computation, and database persistence.
Engineering Choice: Written in Python 3.12 using FastAPI. It is the only runtime that communicates with the PostgreSQL database.
Why it is the best choice: FastAPI provides automated OpenAPI (Swagger) documentation, high-performance async request handling, and strong data validation via Pydantic v2. Keeping database access isolated here protects data integrity and simplifies security rules.

5.2 Data Pipelines (Apache Airflow / Astronomer)

Role: Orchestrates the ingestion of external data.
Engineering Choice: Run via the Astronomer runtime. Airflow handles all API calls, parsing, data transformation, and database writes.
Why it is the best choice: Pipeline execution is asynchronous and runs out-of-band. If an external API (like Copernicus or Open-Meteo) fails, the Airflow scheduler retries the task. The web applications continue to serve the last-cached database record, ensuring the dashboard never goes blank.

5.3 Operations Console (React + TypeScript / Elixir LiveView Interface)

Role: Serves as the internal, real-time interface for utility operators.
Engineering Choice: Delivered as a high-fidelity, responsive single-page application built with React 18, TypeScript, and Vite, which integrates with the Elixir/Phoenix warm-cache edge tier.
Why it is the best choice: It provides the client-side responsiveness, rich interactive charts (Recharts), and smooth local transitions needed for a real-time command cockpit, while leveraging Phoenix WebSockets and OTP processes on the backend for warm-cache data replication. This ensures database queries are optimized via ETS in-memory stores, and allows the UI to degrade gracefully to stale/baseline indicators when connection drops occur.

5.4 Public Citizen Portal (React SPA)

Role: Provides public-facing updates on reservoir levels, drought status, and conservation guidelines.
Engineering Choice: Built with React 18, TypeScript, and Vite, served as a static SPA.
Why it is the best choice: The public portal is physically isolated from the core API and database. It reads a single, daily public_snapshot.json file generated by the Airflow pipeline. Because the public portal has no database connection or direct API access to the core, it is secure by design. This setup also makes the portal highly cacheable via content delivery networks (CDNs).

6. System Features & Algorithms in Boring Detail

Here is the exact technical, algorithmic, and mathematical implementation of every feature in the CWI codebase.

6.1 Reservoir Monitoring

What it does: Aggregates and displays current storage volumes, total capacities, fill percentages, daily inflows, same-day-last-year storage, and locations for the 8 primary reservoirs in Cyprus.
Dams Monitored: Kouris, Asprokremmos, Evretou, Germasoyeia, Kalavasos, Lefkara, Dipotamos, and Achna.
Algorithm/Logic: Ingested raw values are parsed and normalized (e.g., mapping WDD's "Germasogeia" to "Germasoyeia" and "Achna Recharge" to "Achna"). Storage percent-full is calculated dynamically as: $$\text{percent_full} = \left( \frac{\text{current_storage_mcm}}{\text{capacity_mcm}} \right) \times 100$$
Why it was chosen: This is the baseline dataset for all water management in Cyprus. Using actual reservoir data ensures that all downstream risk indices and forecasts are grounded in reality.
Technology: FastAPI endpoint GET /reservoirs fetches records using SQLAlchemy 2.0 ORM from the reservoir_levels table, which stores historical time-series data indexed by reservoir metadata.

6.2 Drought / Scarcity Risk Scoring

What it does: Computes a composite risk score (0 to 100) and risk level for both the nation and individual districts, along with priority actions.
Scarcity Tiers: guarded (score < 45), elevated (45 to 61.9), high (62 to 77.9), and critical (score $\ge$ 78).
Mathematical Formula: The composite score is a deterministic weighted sum of five calculated stresses: $$\text{Score} = (\text{Storage Stress} \times 0.38) + (\text{Yearly Drop Stress} \times 0.18) + (\text{Leakage Risk} \times 0.22) + (\text{Demand Pressure} \times 0.14) + (\text{Inflow Stress} \times 0.08)$$

Where the individual components are computed and clamped between 0 and 100:
- Storage Stress: $$\text{Storage Stress} = \text{clamp} \left( \frac{42 - \text{percent_full}}{42} \times 100 \right)$$ (Triggered when reservoir storage levels drop below a 42% benchmark)
- Yearly Drop Stress: $$\text{Yearly Drop Stress} = \text{clamp} \left( (\text{last_year_percent} - \text{percent_full}) \times 2.1 \right)$$
- Demand Pressure: $$\text{Demand Pressure} = \text{clamp} \left( \left( \frac{\text{demand_estimate_mcm}}{\max(\text{operational_supply_mcm}, 0.1)} - 1 \right) \times 65 \right)$$ Where: $$\text{operational_supply_mcm} = \text{desalination_output_mcm} + \text{recycled_water_available_mcm} + (\text{daily_inflow_mcm} \times 7)$$
- Inflow Stress: $$\text{Inflow Stress} = \text{clamp} \left( \left( 0.22 - \frac{\sum \text{daily_inflow_mcm}}{N} \right) \times 260 \right)$$ (Compares current average inflows against a historical baseline of 0.22 MCM/day)
Why it was chosen: A deterministic, weighted formula is fully explainable. If a district's risk level escalates, operators can inspect the individual components to see exactly which stress factor (e.g., storage stress vs. demand pressure) drove the change.
Technology: Implemented in water_agents.py and exposed at GET /risk-score.

6.3 Reservoir-Level Forecasting

What it does: Projects reservoir storage levels over a 90-day horizon and assesses forecast model accuracy.
Model Design (seasonal-climatology-v1): Built on 35 years of monthly inflow climatology from data.gov.cy (1988–2022). The model assumes a net-zero annual balance. The reservoir gains a fixed seasonal volume (60% of capacity) scaled by historical monthly inflow shares, and loses an equal amount split evenly across the year. The daily change is computed as: $$\Delta \text{Storage}{\text{daily}} = \text{throughput} \times \left( \frac{\text{share}{\text{month}}}{\text{days_in_month}} - \frac{1}{365} \right)$$ Where: $$\text{throughput} = \text{capacity_mcm} \times 0.60$$ The forecast is run iteratively from the current reservoir volume, clamping results between 0% and 100%.
Why it was chosen: A climatology model with historical backtesting is more robust and explainable than machine learning models, especially given the limited direct historical datasets available for individual reservoirs.
Technology: API routes GET /forecast/{reservoir_name} and GET /forecast/{reservoir_name}/accuracy. Calculations are written in pure Python for reproducibility.

6.4 Leak / Non-Revenue-Water (NRW) Detection

What it does: Monitors night-flow telemetry to flag municipal zones with potential leaks, calculates estimated loss rates, and generates inspection tickets.
Algorithm (Minimum Night Flow - MNF): Compares the median night-flow rate from the last 7 days against a rolling 30-day baseline. The system calculates a robust z-score using the Median Absolute Deviation (MAD) to filter out outliers: $$\text{Baseline Median} = \text{median}(\mathbf{X}{\text{baseline}})$$ $$\text{MAD} = \text{median}(|\mathbf{X}{\text{baseline}} - \text{Baseline Median}|)$$ $$\sigma_{\text{robust}} = \text{MAD} \times 1.4826$$ (If MAD is 0, $\sigma_{\text{robust}}$ falls back to $5%$ of the baseline median, or a minimum of $10^{-6}$) $$\text{z-score} = \frac{\text{recent_median} - \text{Baseline Median}}{\sigma_{\text{robust}}}$$ An alert is triggered if the z-score is $\ge 3.0$ and the recent flow exceeds the baseline.
Severity Levels: high ($z \ge 6.0$), elevated ($z \ge 4.0$), and watch ($z \ge 3.0$).
Loss Estimation: The excess flow rate is converted to volume and annualized: $$\text{Loss}_{\text{MCM/day}} = (\text{recent_median} - \text{Baseline Median}) \times \frac{86,400}{10^9}$$
Why it was chosen: Minimum Night Flow (MNF) is the industry standard for leak detection. It identifies leaks when legitimate domestic usage is near zero (between 2:00 AM and 4:00 AM).
Technology: Implemented in backend/app/leak_detection/detector.py. Currently runs on seeded synthetic telemetry (using a SHA-256 hash of the zone name to generate stable baselines and a 14-day leak ramp). The payload is explicitly tagged data_source: "synthetic".

6.5 Satellite Reservoir-Surface-Area Tracking

What it does: Measures and displays reservoir water surface areas over time using satellite imagery to corroborate reported storage levels.
Algorithm/Logic: Queries the Copernicus Data Space Ecosystem (CDSE) Sentinel-2 L2A Statistical API. An evalscript calculates the Normalized Difference Water Index (NDWI) for every pixel in a 5x5 km bounding box centered on each reservoir: $$\text{NDWI} = \frac{\text{Band 3 (Green)} - \text{Band 8 (Near-Infrared)}}{\text{Band 3 (Green)} + \text{Band 8 (Near-Infrared)}}$$ Pixels with an $\text{NDWI} > 0$ are classified as water. The water-pixel fraction is multiplied by the bounding box area to estimate the surface area in km².
Why it was chosen: Satellite tracking provides an independent, public source of truth to cross-reference with self-reported reservoir levels. The Statistical API computes these metrics server-side, avoiding large image downloads.
Technology: Scheduled Airflow DAG satellite_ingest_dag.py queries the CDSE API, saving results to the satellite_snapshots table. The data is exposed via GET /satellite.

6.6 Water-Allocation Scenario Simulation

What it does: Allows operators to adjust six sliders (household reduction, agricultural reduction, tourism change, desalination boost, recycled water boost, and leak repairs) to model how these policy levers affect overall supply and demand.
Mathematical Model:
- Demand allocation: Households (45%), Agriculture (38%), and Tourism (17%).
- Estimated Leakage Loss: $$\text{Leakage Loss}{\text{baseline}} = \text{Demand}{\text{baseline}} \times \left( \frac{\text{Avg Leakage Risk}}{100} \right) \times 0.22$$
- Recovers a portion of the leakage based on the leak repair slider: $$\text{Recovered Leakage} = \text{Leakage Loss}_{\text{baseline}} \times \left( \frac{\text{Repair %}}{100} \right)$$
- The simulator calculates the adjusted demand and supply metrics, and reports the net water saved and the gain in resilience days: $$\text{Resilience Days Gained} = \frac{\text{Net Saved}}{\max(\text{Baseline Demand} / 7, 0.1)}$$
Why it was chosen: This tool allows planners to run "what-if" analyses to evaluate the impact of conservation restrictions and supply adjustments before implementing them.
Technology: FastAPI endpoint POST /scenario-simulation processes typed ScenarioInput payloads and returns results instantly.

6.7 Scarcity-Tier Tariff Simulator

What it does: Models the expected reduction in luxury water use and the resulting surcharge revenue from applying a scarcity tariff. It acts as a primary revenue generator to offset energy-intensive desalination operations.
Surcharges by Tier: guarded (0%), elevated (25%), high (60%), and critical (120%).
Price Elasticity Model: Luxury demand (representing the 17% tourism share, approx. 0.5 MCM/week baseline) is split into two segments:
1. Hotels & Resorts (70% share): Own-price elasticity of $-0.35$ (less elastic, representing commercial operations).
2. Private Pools & Gardens (30% share): Own-price elasticity of $-0.65$ (more discretionary, highly elastic). The adjusted demand for each segment is calculated as: $$Q_{\text{new}} = \max \left( 0.0, Q_{\text{baseline}} \times \left( 1 + \epsilon \times \frac{\text{Surcharge %}}{100} \right) \right)$$
Government Revenue & Cost Offset Projections (Based on a €2.50/m³ Base Rate):
- Scarcity Tier 2 (Elevated - 25% Surcharge):
  - Luxury Demand reduction: Drops from 0.50 MCM to 0.483 MCM/week (saving 17,000 m³ of drinking water weekly).
  - Weekly Surcharge Revenue: €302,000 weekly.
  - Annual Revenue Generation: €15.7 Million per year in auxiliary funding.
- Scarcity Tier 3 (High - 60% Surcharge):
  - Luxury Demand reduction: Drops to 0.465 MCM/week (saving 35,000 m³ of drinking water weekly).
  - Weekly Surcharge Revenue: €697,500 weekly.
  - Annual Revenue Generation: €36.3 Million per year.
- Scarcity Tier 4 (Critical - 120% Surcharge):
  - Luxury Demand reduction: Drops to 0.430 MCM/week (saving 70,000 m³ of drinking water weekly).
  - Weekly Surcharge Revenue: €1,290,000 weekly.
  - Annual Revenue Generation: €67.1 Million per year.
Financial Impact & Desalination Offsets: These surcharges are designed to fund the national desalination energy bill (forecasted at €196M for 2026). At critical drought levels, the €67.1M annual surcharge revenue directly offsets 34.2% of the total national desalination expenditure, securing utility financial resilience.
Why it was chosen: High surcharges during droughts help curb discretionary consumption without restricting essential domestic water use, while generating predictable cash flows to cover high grid-electricity desalination costs.
Technology: Implemented in tariff.py and exposed at GET /tariff-simulation.

6.8 Green Desalination Scheduler

What it does: Optimizes daily production schedules across the four SWRO desalination plants in Cyprus, shifting operations to hours with higher renewable energy availability.
Cyprus SWRO Plants:
- Dhekelia: Capacity of 60,000 m³/day; energy intensity of 3.8 kWh/m³.
- Larnaca (Kiti): Capacity of 65,000 m³/day; energy intensity of 3.5 kWh/m³.
- Limassol (Episkopi): Capacity of 40,000 m³/day; energy intensity of 3.6 kWh/m³.
- Paphos: Capacity of 30,000 m³/day; energy intensity of 4.0 kWh/m³.
Optimization Logic:
- Ingests 24-hour solar and wind forecasts from Open-Meteo.
- Computes a hourly renewable index normalized between 0 and 1: $$\text{Renewable Index} = \text{clamp} \left( 0.7 \times \left( \frac{\text{Solar Radiation}}{900,\text{W/m}^2} \right) + 0.3 \times \left( \frac{\text{Wind Speed}}{12,\text{m/s}} \right) \right)$$
- Adjusts the grid electricity price and carbon intensity based on the renewable index: $$\text{Price}{\text{hour}} = \text{Base Price} \times (1 - 0.5 \times \text{Renewable Index})$$ $$\text{Carbon}{\text{hour}} = \text{Base Carbon} \times (1 - 0.6 \times \text{Renewable Index})$$
- Fills the required daily production target by allocating plant output to the cheapest hours first (merit-order sorting).
- Compares total cost and emissions against a flat baseline operation.
Why it was chosen: Desalination is highly energy-intensive. Shifting production hours to times when solar and wind generation are high reduces operating costs and greenhouse gas emissions.
Technology: Hourly forecasts are pulled by the solar_ingest DAG and saved to solar_forecast. The optimizer in desalination.py serves schedules via GET /desalination-schedule.

6.9 Tourism Demand Forecast

What it does: Projects district demand changes based on tourism activity levels.
Formula: Applies a baseline multiplier modified by the district's tourism pressure index: $$\text{Demand}{\text{forecast}} = \text{Demand}{\text{baseline}} \times \left( \text{District Factor} + \frac{\text{Pressure Index} - 50}{1000} \right)$$ District Factors: Famagusta (1.24), Paphos (1.18), Limassol (1.12), Larnaca (1.08), and Nicosia (0.98).
Why it was chosen: Tourism creates high seasonal demand spikes. This model alerts planners to prepare demand management strategies in tourist areas before peak season.
Technology: Exposed via GET /tourism-forecast.

6.10 AI Weekly Briefing

What it does: Generates structured weekly water risk briefings.
Logic: Assembles computed risk scores, leak alerts, and tourism forecasts into a structured markdown report. The core API can send this structured data to an LLM provider for editing into narrative prose. If the LLM provider fails or is unconfigured, the system falls back to a deterministic, local markdown generator to ensure a briefing is always available.
Why it was chosen: Administrative staff require written summaries. The local fallback ensures the application remains functional even without external LLM connections.
Technology: Endpoint POST /briefing/generate runs through a pluggable provider registry supporting NVIDIA NIM and Anthropic Claude.

6.11 Data Provenance / Lineage

What it does: Records and exposes the source details for every database write.
Logic: For each write operation, a entry is added to the data_provenance table containing the source name, source URL, timestamp, and Airflow DAG run ID.
Why it was chosen: Regulatory and audit requirements demand that all data on public dashboards be traceable to its original source.
Technology: Surfaced via GET /provenance to display data freshness badges in the UI.

Python 3.12 & FastAPI (Intelligence Core): Python is the industry standard for scientific and data processing libraries (like NumPy and Pandas). FastAPI provides high-performance asynchronous operations, automatic Pydantic request validation, and clean OpenAPI spec generation.
PostgreSQL 16: A standard, open-source relational database. It is highly reliable, transactional, and handles our time-series data (weather observations, reservoir levels, forecasts) using standard tables.
Apache Airflow (Astronomer): The industry standard for pipeline orchestration. It provides scheduling, retries, concurrency limits, and execution logging, keeping ingestion completely separate from the API serving path.
Elixir & Phoenix LiveView 1.1 (Operations Console): Runs on the Erlang BEAM virtual machine, providing high concurrency, fault isolation, and low-latency WebSocket connections. LiveView lets us build real-time interactive interfaces with server-side state, and OTP processes enable the warm-cache polling layer.
React 18, TypeScript, & Vite (Public Portal): Vite provides fast local development compilation. TypeScript ensures type safety for the snapshot JSON data, and React makes it easy to build a clean, modular public portal.
Docker Compose: Simplifies deployment by running all runtimes (PostgreSQL, FastAPI, Airflow, Phoenix, React, Nginx, and Grafana) as coordinated containers with isolated networks and shared volumes.

8. Data Ingestion, Sources, & Provenance Matrix

The data pipelines run asynchronously as Airflow DAGs. The following matrix shows where data is sourced and how it is routed:

Source	Target Table	Airflow DAG	Update Frequency	Purpose
WDD Cyprus Dams Monitor API (`dams.wdd.moa.gov.cy/api/latest`)	`reservoir_levels`	`reservoir_ingest`	Daily	Real-time dam levels and percent-full metrics.
WDD Weekly Excel Report (`moa.gov.cy`)	`reservoir_levels`	`reservoir_ingest` (Fallback)	Weekly	Backup verification source if the JSON API is down.
data.gov.cy Historical Data	Loaded via seed	N/A (Static)	Once (Seed)	35 years of inflows used to construct monthly climatology shares.
Open-Meteo Meteorological API	`weather_obs`	`weather_ingest`	Hourly	High-resolution precipitation and temperature data.
Copernicus Sentinel-2 CDSE API	`satellite_snapshots`	`satellite_ingest`	Weekly	NDWI calculations to verify water surface area.
Open-Meteo Solar & Wind Forecast	`solar_forecast`	`solar_ingest`	Daily	24-hour wind speed and solar radiation forecasts.

Provenance Philosophy

Data integrity is maintained by recording provenance metadata for every transaction. If a value on the dashboard is questioned, an operator can query the data_provenance table using the API to find the exact source URL, API endpoint, timestamp, and Airflow DAG run ID that wrote the record.

9. Physical Sensor Layer Procurement Specification

CWI includes mock data components for network pressure, water quality, and district night-flow meters. To transition these features to live operations, physical telemetry sensors must be deployed across the Cyprus distribution network.

10.1 Backend Python Tests (`pytest`)

The backend contains 22 test files under backend/tests/ covering endpoints, ORM schemas, and algorithms in isolation:

Computational Tests: Verify risk scoring calculations, scenario simulation rules, tariff elasticity models, desalination optimization logic, and tourism forecasts.
Deterministic Seeds: Synthetic data generators use fixed random seeds. This ensures that tests are repeatable; leak alarms must trigger consistently on test runs.
Database Isolation: Tests requiring database access run against a dedicated PostgreSQL database on port 5433 (cwi_test). The test suite wraps each test in a database transaction and rolls it back afterward, preventing test runs from polluting each other.
Graceful Database Skips: If the test database is offline, pytest skips the database-dependent tests and displays a setup warning, allowing the rest of the unit tests to run anywhere (such as local development environments without Docker).

10.2 Model Validation & Forecaster Backtesting

The reservoir-level forecaster (seasonal-climatology-v1) is validated using a statistical leave-one-year-out backtest over 35 years of monthly inflow records. For each year, the model is trained on all other years to predict the target year's monthly inflows. The errors are calculated and stored:

Mean Absolute Error (MAE): Measures average absolute prediction deviation.
Mean Absolute Percentage Error (MAPE): Normalizes the error as a percentage. This accuracy data is saved to the forecast_backtests table and exposed via GET /forecast/{reservoir_name}/accuracy so users can see how reliable the forecast model is.

10.3 Airflow Pipeline Tests

DAG Parse Integrity: Verifies that all Airflow DAGs parse correctly without syntax or import errors.
Ingestion Idempotency: Confirms that running the ingestion scripts multiple times does not result in duplicate database entries.
Public Snapshot Isolation: Verifies that the public_snapshot_dag.py only exports the specified allow-listed fields, preventing internal operational data from reaching the public folder.

10.4 Operations Console Tests (`ExUnit`)

LiveView Page Tests: Verifies that LiveView pages render correctly, including when backend data is missing or degraded.
Poller & Warm-Cache Validation: Verifies that the console's polling loop updates the ETS cache table and broadcasts updates to client sessions over Phoenix PubSub.

10.5 Frontend React Tests (`Vitest`)

Snapshot Verification: Asserts that the React code correctly parses the snapshot JSON, formats timestamps, maps scarcity tiers, and handles missing values.

11. Deployment, Operations, & Security Architecture

11.1 Deployment & Infrastructure Configuration

Containerization: The system runs as a multi-container Docker Compose stack.
Container Inventory:
1. postgres (Runs PostgreSQL 16)
2. backend (FastAPI core application)
3. frontend (Serves React portal assets via Nginx)
4. pipelines (Astronomer Apache Airflow scheduling environment)
5. edge (Phoenix Operations Console)
6. grafana (Serves operational performance dashboards)
Configuration: Environment variables are configured using a local, uncommitted .env file (e.g., Copernicus API credentials and LLM keys). If keys are missing, the system runs with fallback configurations (satellite functions use cached files, and AI reports default to local markdown).

11.2 Operational Monitoring

Grafana: A pre-configured Grafana dashboard connects directly to the PostgreSQL database to track key metrics (system data writes, daily inflows, leak warnings, and pipeline run durations).
Logging: API logs are routed to stdout/stderr inside the Docker network. Airflow records task runs to persistent storage volumes for easy debugging.

11.3 Security Hardening

Local Network Bindings: By default, all container ports (such as the database port 5432 and the backend API port 8000) bind to 127.0.0.1. They are inaccessible from external interfaces, restricting access to localhost.
Network Isolation: Only the Operations Console (Elixir) and the Airflow pipelines can communicate with the backend API on the internal container network.
Public Boundary: The Public Citizen Portal has no network access to the database or internal APIs. It only reads the public public_snapshot.json file.
Supply Chain Audits: The build process uses Trivy to scan containers for vulnerabilities and generates CycloneDX SBOMs for dependency tracking.

12. Operations Console Software Interface

The CWI Operations Console is served as a high-fidelity, responsive single-page application built with React, TypeScript, and Vite. It organizes the 11 backend core features and supplementary control panels into 15 specific live views, grouped logically in the sidebar layout:

Cyprus Water Intelligence System (CWI) — Executive Project Overview

1. Executive Summary

The Cyprus Water Intelligence (CWI) system is a next-generation water management and decision-support platform custom-built for the Water Development Department (WDD) of the Republic of Cyprus.

Cyprus is facing a severe, compounding water crisis:

Reservoir capacities fell to ~13.7% in early 2026.
The nation faces a structural annual water deficit of 14 million cubic meters.
Municipal distribution networks lose up to 40% of drinking water through leakage (non-revenue water).
Tourism-driven luxury demand (swimming pools, gardens, hotels) consumes up to 500 liters per person daily, far exceeding the EU average of 120 liters.
Desalination (SWRO) provides 70% of drinking water but consumes 12% of the national electricity grid load, running on carbon-heavy fuels.

CWI acts as a centralized operations dashboard. It aggregates satellite observations, meteorological forecasts, reservoir levels, and simulated district telemetry into a single, intuitive interface. This allows public administrators and utility operators to manage water scarcity, detect distribution leaks, shift desalination production to low-cost solar/wind hours, and raise funding through smart scarcity-based surcharges.

2. Core Modules & Operational Features

The CWI system coordinates 11 integrated modules to manage national water infrastructure:

2.1 National Reservoir Monitoring

CWI monitors active storage levels, daily inflows, and locations for the 8 primary dams in Cyprus (Kouris, Asprokremmos, Evretou, Germasoyeia, Kalavasos, Lefkara, Dipotamos, and Achna). It compares current storage against same-day-last-year baselines to identify water stress.

2.2 Climatology-Based Storage Forecasting

Using 35 years of official inflow data (1988–2022), CWI projects reservoir levels over a 90-day horizon. This allows water planners to foresee dry-season storage depletion and make informed water allocation decisions.

2.3 Acoustic & Night-Flow Leak Detection (IoT)

By monitoring municipal pipe inflows during the early morning (2:00 AM – 4:00 AM), CWI flags abnormal water flow. If the flow rate deviates significantly from the 30-day baseline (indicated by a high z-score), the system flags a leak, estimates the hourly water loss, and enables operators to dispatch field crews.

2.4 Satellite-Based Surface Area Corroboration

CWI integrates Copernicus Sentinel-2 satellite data to calculate the Normalized Difference Water Index (NDWI) over reservoirs. This acts as an independent, tamper-proof audit of reported storage levels.

2.5 Green Desalination Merit-Order Scheduler

Desalination is highly energy-intensive. CWI ingests hourly solar and wind forecasts from Open-Meteo and schedules plant output during peak renewable generation hours. This shifts power load away from expensive grid hours, reducing emissions and power bills.

2.6 Satellite Crop Moisture & Irrigation Advisor

Monitors agricultural zones using Copernicus NDVI (vegetation greenness) and NDMI (canopy moisture stress) indexes. By correlating crop stress with 72-hour rain forecasts, the system issues automatic irrigation reduction advisories to conserve water (e.g., "Reduce Kiti zone release by 40% due to incoming precipitation").

2.7 Scarcity-Tier Tariff Simulator (Revenue Model)

Models price-elasticity responses to surcharges applied to luxury tourist water usage (hotels, resorts, private pools). Surcharges scale by drought severity (0% to 120% surcharges) to suppress discretionary demand and raise revenue to offset desalination utility bills.

2.8 Graphical Data Explorer

A visual search builder allowing water planners to explore historical storage, daily inflows, leakage indexes, and weather history, outputting clean charts and grids without requiring database query programming.

3. Financial Projections: Desalination Offsets & Surcharge Revenues

The Scarcity-Tier Tariff Simulator acts as a primary funding source during droughts. Based on a standard base water tariff of €2.50 per cubic meter and a baseline luxury usage of 0.50 Million Cubic Meters (MCM) per week, the WDD can project the following financial outcomes:

Scarcity Tier 2 (Elevated Drought - 25% Surcharge):
- Water Saved: 17,000 m³ weekly.
- Weekly Revenue Raised: €302,000.
- Annual Revenue Generation: €15.7 Million in additional utility funding.
Scarcity Tier 3 (High Drought - 60% Surcharge):
- Water Saved: 35,000 m³ weekly.
- Weekly Revenue Raised: €697,500.
- Annual Revenue Generation: €36.3 Million.
Scarcity Tier 4 (Critical Drought - 120% Surcharge):
- Water Saved: 70,000 m³ weekly.
- Weekly Revenue Raised: €1,290,000.
- Annual Revenue Generation: €67.1 Million.

Offsetting the National Desalination Bill Cyprus's desalination operating costs are budgeted at €196 Million for 2026. Under critical drought conditions (Tier 4), the €67.1 Million in annual surcharge revenue will directly fund and offset 34.2% of the national desalination energy bill, protecting public water utilities from financial strain.

4. The Operations Console (Software Interface)

The internal software console is designed as an interactive, real-time cockpit for utility operators. It organizes the system into 15 specific views grouped under 4 main navigation tabs:

OVERVIEW:
- System Overview: Renders national metrics, real-time SCADA telemetry feeds, and system flow rates.
- Command Center: Unified situation room. Features an interactive deficit area chart and a Command Action Deck to trigger Desal Boosts, apply Scarcity Surcharges, deploy repair crews, redirect wastewater, or drawdown pressure. It includes an AI Operations Dispatch Agent in the bottom right for instant conversational QA.
- Asset Map: Geographical view mapping locations, capacities, and active storage for reservoirs and plants.
OPERATIONS:
- Anomaly Detection: Diagnoses leaks, estimates losses, and dispatches field teams.
- Work Orders: Ticketing queue to assign engineers and track task statuses (Open, In Progress, Resolved).
- Maintenance: Scheduled equipment checks and sanitization audits.
- Green Desalination: Previews hourly plant production schedules and cost/emissions savings.
- Crop Moisture: Monitors agricultural soil moisture trends and issues irrigation warnings.
PLANNING & ANALYTICS:
- Model Predictions: Projects reservoir storage levels over 90 days and displays historical model accuracy.
- Scenario Simulator: Lets planners adjust policy sliders to estimate water savings.
- Data Explorer: Search and download historical datasets as charts or table logs.
- Data Quality: Tracks data completeness and freshness, featuring Data Provenance Badges.
CONFIGURATION:
- Integrations: Tracks API latency status checkmarks (Open-Meteo, Copernicus, SCADA) and Airflow cron timers.
- Rules & Alerts: Set trigger conditions (e.g. Quality Index < 90) and edit notification lists.
- Users & Roles: Admin portal to manage operators, control permissions, and review security checklists.
- AI Weekly Briefing: Generates structured weekly narrative reports and handles assistant chat queries.

5. Security & Isolation

CWI maintains strict boundaries between internal operations and public-facing portals:

Operations Console Binding: All backend APIs and databases bind strictly to localhost, protecting the platform from unauthorized external network access.
Public Portal Isolation: The citizen-facing portal has no direct connection to the database. It reads a static, daily snapshot file (public_snapshot.json) that only contains pre-cleared, public-safe data. Internal metrics, operator profiles, and security rules can never leak.
Idempotency & Resilience: Airflow ingestion runs out-of-band. If an external API fails, the console continues to display cached data rather than going blank.
