Blue-Meteo – Water Retention System

Weather-driven retention system – fully automatic

Controlled water discharge, reduced water nuisance

Sustainable reuse of stored rainwater

Smart integration with irrigation and greywater systems

What is Blue-Meteo?

Extreme rainfall, prolonged droughts, and heat stress are placing increasing demands on urban water management. Blue-Meteo offers an innovative solution to these challenges: a weather-driven retention system that stores, manages, and makes rainwater available for reuse.

Based on current and forecasted weather data, the system decides whether rainwater should be retained, gradually discharged, or redirected to another buffer or application. Blue-Meteo helps prevent flooding during heavy downpours, eases the load on sewer systems, and enables circular use of rainwater for irrigation or cooling during dry periods.

Blue-Meteo is ideal for use on retention roofs, in underground or above-ground water reservoirs, or in combination with a greywater circuit. Moreover, the system can easily be linked to our smart irrigation system Irriview, for a complete and integrated water management system.

Blue-Meteo thus supports climate-adaptive urban development, with smart water management and improvement of the urban microclimate at its core.

What are the benefits of Blue-Meteo?

Minimizing flooding during heavy rainfall – Blue-Meteo regulates rainwater discharge based on real-time and forecasted weather conditions. This reduces pressure on the sewer system and limits water nuisance during intense storms.
Reduces heat stress and energy consumption – Blue-Meteo enables evaporation of stored water during warm periods, actively contributing to the cooling of buildings and outdoor spaces. This natural cooling process reduces heat stress and lowers the energy consumption of mechanical cooling systems.
Sustainable reuse of rainwater – Blue-Meteo buffers rainwater on roofs or in reservoirs and reuses it for the irrigation of rooftop gardens, green facades, or public greenery, or as a supplement to a greywater buffer. This way, the system optimally utilizes rainwater, saves precious drinking water, and contributes to circular water use in the city.
Automated and reliable water management – Blue-Meteo automatically manages the collection, storage, distribution, and discharge of rainwater using advanced software, sensors, weather data, and motorized valves and/or pumps.
Flexible integration with other systems – Blue-Meteo can be easily connected to greywater circuits or our Irriview irrigation system for an integrated solution in water and green management.

Smart retention system for sustainable rainwater management

Extreme rain events and prolonged droughts place high demands on urban water systems. Blue-Meteo handles this process fully automatically using advanced software, sensors, and motor-controlled shut-off valves. The system continuously monitors water levels in buffers, analyzes weather forecasts, and controls water flows: rainwater is retained, discharged, or redirected to another buffer, an irrigation system, or a greywater circuit.

How Blue-Meteo works step by step:

Weather data analysis
Blue-Meteo processes real-time weather data 24/7 and anticipates upcoming precipitation. This ensures the system knows when and where buffer capacity is needed.
Measurement of buffer capacity
Smart sensors measure the current water level in retention roofs or other buffers. Blue-Meteo thus knows exactly how much space is available to collect new rainfall.
Controlled discharge or redistribution
If buffer capacity is insufficient, Blue-Meteo automatically and gradually discharges excess water to other buffers, surface water, or the sewer system. This reduces peak loads and mitigates flooding.
Storage and reuse
Blue-Meteo efficiently stores rainwater in buffers such as retention roofs, underground tanks, or basins, and directs it to where it’s needed – for example, another buffer, an irrigation system, or a greywater circuit.
In dry periods, the buffered water can be used for irrigating rooftop gardens, green facades, or other vegetation. The system also enables evaporation and can actively pump water to retention roofs for cooling or as irrigation water for intensive roof vegetation.
Blue-Meteo optimally utilizes rainwater and significantly reduces drinking water consumption.
Powerful integration with Irriview
When combined with our smart irrigation system Irriview, Blue-Meteo becomes part of a complete and integrated solution for sustainable water and green space management – fully remotely controlled.

Advanced technology for rainwater management

Blue-Meteo is equipped with high-quality, motor-controlled valves and robust technology that ensures reliable water management—regardless of weather conditions.

Technical specifications and features:

Compatible with various drainage systems
Blue-Meteo can be integrated with “Pluvia” and “Quickstream” systems, as well as traditional rainwater drainage. This makes the system flexible and applicable to virtually any type of roof.
Valves with heating and IP67 rating
The valves are equipped with a heating element and position feedback and comply with the IP67 standard. This makes them robust enough for both indoor and outdoor installation, ensuring durable performance in all weather conditions.
Sensor-driven controlled discharge
A rooftop sensor measures the water level and calculates available buffer capacity. Based on weather forecasts, the system automatically determines whether to retain or gradually release the water.

Water storage & buffering

For those needing additional buffer capacity, Mastop offers various solutions for rainwater storage. Think of concrete or plastic silos and storage tanks. Depending on the location and purpose, these buffers can be placed above or below ground. These buffers are flexibly deployable for temporary or long-term rainwater storage.

We deliver these solutions tailor-made and can also assist with installation and integration with water management systems if desired.
