Over the last 100 years, the annual amount of rain has increased by approximately 15%. Along with this, the probability of extreme rain events in the future is increasing. There’s a need to rethink how to handle the future with increased precipitation and more heavy rain events.
A sports field is not one of the solutions that immediately pops into mind. However, due to the size and openness of such fields, they are in fact highly efficient to handle and collect stormwater and become multifunctional – both handling stormwater from the sports field itself and the surrounding areas.
The water is collected under the field in an underground stormwater retention system. This way the field can be used both under and after major precipitation events.
When creating an underground retention system under a sports field, the rainwater will seep onto the field or is led to the system from the neighboring areas. If the sports field is made with natural grass, the rainwater can seep directly through the field and down into the underlying fascines. From here the water can be delayed by using stormwater chambers and infiltrates into the underlying soil.
If the field has artificial turf, the water can be led to the stormwater chambers through gutters and inlet wells as it would need to be diverted around the underlying membrane under the turf.
We find an example of a multifunctional football field in Snättringe close to Stockholm, Sweden. In Snättringe there was an urgent priority to establish an underground retention systemdue to the low-lying areas around the football field being at the risk of becoming flooded during major precipitation events.
The football fields will be fully transformed by the end of 2021 with underground water retention vaults with a capacity of containing up to 1600 m3 stormwater. For this project we contributed with our stormwater management system Aquaton. The project was planned with Stockholm Vatten och Avfall and established with SVEAB anlägging.
