Microsoft has taken another step forward in its water replenishment efforts by partnering with Dutch startup FieldFactors to collect rainwater at a new development in Madrid, Spain.
As part of the collaboration, Microsoft and FieldFactors will work together to capture up to 200 million liters of stormwater runoff annually from the Solana de Valdebebas development. The collected rainwater will then be treated using advanced biofiltration technology before being discharged into the local Valdebebas stream, which is a tributary of the Jarama River.
The innovative approach taken by FieldFactors focuses on locally capturing and treating rainwater for reuse or to return it to natural bodies of water. This method not only safeguards cities from flooding and heat stress but also conserves freshwater resources and promotes biodiversity.
FieldFactors’ BlueBloqs sustainable drainage system will be used to collect the rainwater, while the G-Aqua Research Group of Universidad Politécnica de Madrid (UPM) will assist in designing the stormwater harvesting strategy and monitoring water quality results.
Microsoft’s involvement in this project is part of its commitment to addressing global water challenges. The company has already undertaken initiatives such as partnering with FIDO Tech on AI-led leak detection in London, which was later expanded to projects in Phoenix, Arizona, Queretaro, Mexico, and Las Vegas, Nevada.
As Microsoft’s water lead, Eliza Roberts emphasized the importance of not only replenishing water but also reducing consumption. She highlighted that Microsoft is working with a range of startups, non-profits, and private organizations to deliver water replenishment projects around the world.
