Working on building a blue-green infrastructure with a solid stormwater solution is a puzzle of size and space below-ground. It's also about sustainability and environmental impact, traffic load, maintenance requirements, local regulations and more. Small actions and making every decision count can have a big impact on resolving this puzzle.
Enabling rainwater reuse
Required by law in most countries, rainwater tanks to prevent flooding, currently lay empty 95% of the time, with most of the water released to the sewer system after a heavy rain. If we used available technology, we could reuse the water to maintain greenery and infiltrate it back to our groundwater to avoid depletion.
Avoiding sewer overflows in heavy rainfall
Digital tools like sensors that enable predictive maintenance and improved product design can protect the city’s sewer systems from failing due to clogging. Sensors can monitor and ensure cleaning is done only when needed – saving the city costs and resources. While road gullies with features like filter options protect the sewers from clogging due to debris.
Now more than ever our cities need trees to create shade, resist heat stress and provide us with comfort. And with increased heavy traffic, stress and more paved areas, our trees face difficult conditions. We can help through simple solutions like a root tank which provides trees with air to breath and collects water for dryer periods.
We need to future-proof our assets and create new standards. In this process, I ask the question: How do I build solutions that last – despite things like urbanisation, shortage of raw materials, climate changes, digitalisation? It's all within my depreciation time! I am making things for 30 years and in 30 years, it will be 2050! Then we have arrived in a completely new world where we are climate-adaptive, circular, carbon neutral, future-proof, smart.Sacha Stolp , Director of Innovation for the Future-Proof Assets Program in Amsterdam
