Rainwater Runoff Well
Cities have to deal with a lot of peak showers due to the climate change. These peak quantities cannot be discharged via the sewer. As a result, streets are flooded more often. Wadis are being constructed in order to realize more reception capacity. Because wadis are filled with rainwater that comes from the streets, wadis become polluted.
A small prototype has been developed to see if this well can filter the polluted rainwater with a biochar filter.
The rainwater well is made of PP, which is one of the more durable and easily recyclable plastic products.
The filter in the rainwater well can be filled with (activated) char.
This filter system can be placed in the vicinity of infiltration facilities to purify rainwater before it is absorbed into the ground.
