A Healthy City is built with water.

Worldwide people are moving to large metropolitan areas, while at the same time our climate is changing. With an increase in paved areas and a decrease in green space we have to rethink the way we've been building cities.

Water as resource

Stormwater as valuable resource.

Today, 55% of the world’s population live in urban areas and this is expected to increase to 68% by 2050 according to the United Nations. At the same time weather patterns are changing. The average temperature is rising, dry spells are more frequent and rain falls in shorter and more intense rainstorms.

Population growth in cities leads to more buildings and paved areas, in turn decreasing the amount of green infrastructure. This reduces the capacity for rainwater infiltration which, in combination with an increasing quantity of rainstorms, leads to more frequent and severe occurrences of urban flooding.

At the same time these built areas collect energy from the sun during the day and radiate this back into the city as heat during the night. In metropolitan areas the night-time temperature can be as much as 8 to 10 degrees warmer than the surrounding countryside. Where nature creates a microclimate in which it thrives, human settlements suffer from this Urban Heat Island effect, negatively impacting human lives and well-being.

Improving city life.


Smart water management for healthy cities.

The Permavoid range of products and systems are capable of creating circular, nature-based solutions for sustainable water management in metropolitan areas. Solutions encompass urban trees, Blue-Green roofs, podium decks, gardens, sports pitches and SuDS aiming at water sensitive design.

Rainwater is intercepted at ground level for reuse on rooftops and inside our tallest buildings, all helping to mitigate the impact of climate change and reinforcing a positive outcome for a growing population.
