Circular Water System

Demonstrator Project supported by EIT Climate KIC

About bluebloqs

A Nature-based Solution to create water reserves in urban areas

The changes in the rain cycles generated by global warming have alarmingly increased the number of droughts and floods in the world, seriously affecting our cities.

This problem is enhanced by our lifestyle and by the emissions that come from it.

Now is the time to implement solutions to mitigate the adverse impacts of changes in rain cycles.

Our solution for rainwater managing is Nature-based, and it's designed to mitigate the impacts of droughts and floods at the same time as it allows the generation of water within the urban fabric of cities.

Bluebloqs Circular Water System Demonstrator project is supported by EIT Climate KIC.

About bluebloqs

Bluebloqs has the potential to transform the entire urban water infrastructure into a decentralised grid of circular water systems.

By 2030, the urban water demand will be supplied by a portfolio of local water sources, powered by nature.

Healthy urban water systems are fundamental for our lives. We need them to secure food and drinking water production, clean air, social and economic welfare, even for our health and happiness. But because of climate change and rapid population growth, cities are challenged to keep the water cycle in balance.

An innovation powered by nature

Bluebloqs is compact system for rainwater collection, treatment, atorage and reuse in urban areas, with the aim to catalyze the urban transition towards circular water systems, making cities climate-resilient. The essence of the Bluebloqs technology is:

• Collection of stormwater run-off from paved surfaces, such as roofs, streets and parking. • Retention measures at ground level to temporary retain the collected stormwater. • Treatment of the collected stormwater by means of bio-filtration techniques within Bluebloqs Biofilter. • Storage of the purified water in the deeper sand layers via infiltration wells. • Reuse of the infiltrated water for different applications, such as irrigation of sport fields and urban green, industrial processes or reducing heat stress


Makes cities climate resilient street by street

This circular water system has the potential to generate water resources within the urban fabric, ensuring you green parks, great sporting pitches every season, and good quality water for industrial use

Climate KIC Partners

A consortium formed by Delft University of Technology, Aquafin, Technical University of Madrid, KU Leuven, KWR Water, Field Factors, I-Catalist, and the Municipalities of Someren and Pijnacker-Nootdorp, will collectively work in a two-year programme to test and showcase the upscaling potential of this innovation in Europe.
