BWI digitizes river basins

BWI, which stands for Blue Water Intelligence, is a hydrology startup company established in June 2022 in Toulouse, France. BWI specializes in the monitoring of continental surface water reserves, and forecasting of inland water quality, levels, volumes and river discharge around the globe. Our 4-word pitch is ‘BWI Digitizes River Basins’. Currently, BWI services are available or in the process of becoming available in Europe (France), Africa (Senegal, Ivory Coast) and South Asia (India, Bangladesh, Népal), and is willing to expand to new geographical areas.

Basin digitization is what we do

Continental freshwater data & insights


of the Earth’s water is fresh. Together, let’s take good care of this scarce and yet vital resource, so that it will be available for our future generations too! 

A State-of-the-Art approach to predicting streamflow, water levels and water quality

BWI brings together in-situ data, spaceborne observations and machine learning to feed and empower hydrological and hydrodynamical models.

As a provider of online subscription-based services, BWI aims to make scalable – across space and time – hydrological data to address climate change induced water stress.

Help governments and companies adapt to climate change

Improvements in the forecasting of water resource availability, water quality, floods, and droughts both at local and regional scales will help local authorities and businesses build climate resilience, as well as contribute to enabling scientists to better understand the water cycle.

At BWI, we also want to accelerate the transition to a low carbon society by enabling low carbon industries, such as, for instance, hydropower electricity generation or inland water transportation, to grow at maximum speed.

Virtual stations to help our clients digitize river basins

Public authorities & institutions

Predict water hazards and provide water-related monitoring (quality, streamflow, levels, volumes)

BWI builds predictive flood and drought early warning systems for risk managers, municipalities, basin management authorities and international finance institutions. BWI also provides predictive water quality monitoring solutions. To simulate the propagation of turbidity, contaminants and invasive plants along river networks.
Science and risk portfolio managers

Data on water levels, updated daily, from a low-orbit hydrological constellation of nanosatellites

BWI is working on making the SMASH concept (Small Altimetry Satellites for Hydrology), bord at research center LEGOS and designed at CNES (Phase A completed), a reality to cover the globe with continental surface water level measurement points updated on a daily basis. 30.000 comparable inland water height data points updated daily would be tremendous material for scientists, NGOs, governments, basin authorities as well as for global corporations such as insurance and industry.
Run-of-river hydropower operators and energy aggregators

Forecast river discharge and water levels accurately

BWI enables run-of-river hydropower operators to increase revenues by making possible the integration of streamflow predictions in their business processes. BWI is capable of accurately predicting future river discharge and deliver this valuable data to hydropower operators and energy traders through an API.
