The Barcelona City Hall teamed up with MICA ECO to pilot a data-driven approach to household water management during drought conditions.
The Challenge
Barcelona, like many cities around the world, faces growing water scarcity. Climate change is reducing rainfall, droughts are becoming more frequent, and urban populations are increasing. Household water use is a critical lever to reduce demand, yet cities often lack the detailed, real-time data to understand where water is being used and how to influence behaviors effectively.
Traditional approaches — blanket campaigns or restrictions — are often untargeted and inefficient, leaving municipalities unprepared to manage demand during droughts.
Barcelona wanted to explore whether high-resolution household water data and AI-driven insights could help households reduce consumption while empowering citizens.
The Pilot
MICA ECO was selected as the winner of the "La Ciutat Proactiva 2024: Missió Sequera" challenge to design and run a pilot study.
Design & Development
We designed and developed the MICA system from scratch, including the sensor, the AI models and the purpose-built app.
We worked with pilot users to train our AI algorithms by manually tagging over 10,000 water events and co-designed a behaviour-change app for water demand reduction.
Deployment
We installed a single high-resolution sensor in 25 households, capturing household water activity without intrusive multi-sensor setups.
Data Collection & Analysis
We collected real-time household water flow data, disaggregated by activity — showers, laundry, dishwashing, etc.
Residents received personalized, actionable insights through their app, helping them adjust behaviors sustainably.
City Insights & Recommendations
We delivered a time-bound study showing:
- How activity-level insights delivered in real-time through our app impacted water consumption
- Aggregate distribution of water use by activity, including high-usage behaviors and most common inefficiencies
- Recommendations for targeted campaigns, interventions, and policy actions
Outcomes & Impact
Up to 30% reduction
In household water use among participating households.
Empowered residents
Households gained awareness and adopted more sustainable water habits.
Actionable insights for the city
Enabling Barcelona to explore evidence-based drought management policies.
Why this matters
The Barcelona pilot demonstrates that cities can leverage personalised activity-level insights and citizen engagement to reduce water demand. By combining:
High-resolution measurement
Accurate, real-time data capture
AI-driven activity analysis
Intelligent water use disaggregation
Co-designed resident-facing insights
User-friendly, actionable feedback
Municipalities can:
- Encourage sustainable household behaviors
- Deliver targeted, effective campaigns
- Make informed policy decisions
Barcelona's pilot serves as a repeatable model for other cities seeking a data-driven, citizen-focused approach to urban water management.
