One option for creating additional water storage facilities is storing in underground crates. This is a hidden technology that fits the criteria of sustainable urban planning. An interesting form of multiple uses of single spaces is realising water storage beneath sports fields. The technical aspects are simple to achieve using storage boxes/bulbs. Sports fields can be integrated into water systems in one of two ways. Firstly, the water storage facility is connected directly to surface water. In this scenario, the water level below the sports fields rises according to the surface water level. This is a simple system to operationalise. Fluctuations in the water levels are limited by the maximum fluctuation of the surface water level. Secondly, the water storage facility is not connected directly to surface water. In this scenario, the water that needs storing is fed in from elsewhere, stored and drained at a delayed pace. This allows for more water to be stored, since greater fluctuations in water levels are possible.

Co-benefits and impacts

Apart from reducing runoff during precipitation and flood events, rainwater storage beneath sports fields enables the multifunctional use of the specific area without causing any aesthetic damage of the landscape.
