The "Calzada del Agua" project is an innovative solution that aims to improve water management in Mexico. The country suffers from water shortages, urban flooding due to excess rainfall, pollution, and overexploitation of aquifers, among other water-related problems. Our proposal is to offer a circular water solution, which allows collecting, purifying, storing and recovering rainwater.

To understand and visualize the technical, social, economic, and urban aspects to be able to apply this solution, we carried out a feasibility study in the city of Oaxaca de Juárez. To do this, we took a sector of the Master plan for Calzada de la Republica (2019) and selected a space, the Plaza Yucatán, and an end user for the recovered water, the Mercado de la Merced public market, located a few meters from the main street.
In this space, the Bluebloqs technology was applied, which solves the excess and/or lack of rainwater in a circular manner, supplying water to the market and recharging the aquifer. The square was selected thanks to an urban toolkit, specially designed to define urban spaces where resilience measures can be applied.
The result of the study shows that with this comprehensive solution, it is possible to generate resilient spaces in Mexican cities where water is used efficiently to solve scarcity, pollution, and demand.
The project was successfully carried out by the consortium of which we are part, together with the Dutch company Field Factors and the Mexican partner Centro. The feasibility study was supported by the program “Innovations for Water Safety and Water Security (IVWW) de Partners for Water 2022-2027”.
