Who we are

GBM, SUSTAINABLE DRAINAGE EXPERTS

Green Blue Management S.L. (GBM), is a consulting company founded and managed by Dr. Sara Perales, PhD in Civil Engineering.
The company has nearly two decades of experience being the benchmark company for Sustainable Drainage Systems in Spain. GBM was born aiming to apply the international experiences of her founder, in countries with very diverse climates.

At GBM, we work to make cities and environments healthier and more resilient, integrating stormwater management into the urban landscape with rain gardens, permeable pavements, green roofs and other techniques.

Since 2018, GBM is part of the TYPSA Group, an independent consulting and engineering services group, and a leader in infrastructure, energy, environmental and city solutions. This integration has allowed GBM to expand and participate in emblematic projects.

Since its foundation in 1966, TYPSA Group has supported public, private, and institutional clients in developing transport, water, buildings, renewable energy and rural development projects, from concept through to commissioning and operation.

We have participated in projects for both public and private clients, offering innovative nature-based solutions, reducing energy consumption in water management, protecting the environment and collaborating with adaptation to climate change strategies. All these ideas are aligned with the UN Sustainable Development Goals.

Some of our remarkable contributions are our participations in the Sustainable Drainage Systems design present in the Wanda Metropolitano Stadium in Madrid, the Bon Pastor neighbourhood in Barcelona and Av. El Greco in Sevilla, among others. Moreover, GBM has drafted SuDS design guides for Madrid, Castellon de la Plana and Valencia city councils.

At an international level, we have contributed to the Riyadh Sports Boulevard project in Saudi Arabia, Bus Connects Core Bus Corridors or N22 Macroom to Bailde Bourne bypass in Ireland, among others.

Sustainable Drainage Systems (SuDS) constitute a strategy for adaptation to climate change in the urban environment.

They help manage flood and drought risks through Nature-based Solutions (NBS) that complement traditional drainage infrastructure.

CEO of Green Blue Management

While cities continue increasing the amount of concrete and asphalt, the use of SuDS allows breaking the ground impermeability and serves as a support to the creation of green areas that generate kind spaces for people.

Supporting traditional drainage, SuDS generate added value, reducing energy and urban water treatment costs, and improving the quality of discharges to the natural environment.

Alberto Gay Garrigues

Civil Engineer

To make sustainable stormwater management a reality in our cities, it is necessary to involve all the stakeholders. Promoting the knowledge of SuDS, both among technicians and residents, we promote a collaborative and inclusive design of our cities, generating a space designed for people.

The intelligent stormwater management configures our urban space, improving landscape quality and, at the same time, promoting habitats with great biological diversity.

Elena Calcerrada Romero

Civil Engineer

The application of Nature-Based Solutions in urban drainage constitutes an important innovation compared to conventional drainage techniques.

Likewise, the use of this new methodology must go in parallel with the process of innovation and transformation that is taking place in the construction industry. In this scenario, the new information technologies and the BIM methodology must play an important role throughout the cycle life of the SUDS, facilitating their construction, maintenance and monitoring.

Miguel Rico Cortés

Civil Engineer

The rapid urban growth in recent decades has led to an increase in the water demand, as well as an increase in impervious surfaces in cities. Consequently, a change in strategic urban planning towards more sustainable water management is necessary.

The incorporation of SuDS, as part of this process, enables to achieve a more efficient runoff management but also to create greener and more comfortable spaces for citizens.
