Eco-tank is an underground, pre-cast water storage system that holds large volumes of water in the event of storms, which can then be utilised for greening projects at a later date. The system supports flood control measures and helps protect urban environments from flood damage. In Japan, our Eco-tank system is often installed beneath a range of public spaces, including school playing fields, parks, baseball grounds, tennis courts and carparks.

The system brings the added benefit of being quick to install due to our use of pre-stressed long-span structures. Structures of this type require fewer internal pillars, which makes their construction much faster than conventional water storage facilities. As a result, Eco-tank is ideal for school as these buildings are often erected within a short timeframe.

The tanks are installed below the flood control basin, which it itself situated next to a watercourse. If water overflows from the river, it is first captured within the storage tanks. However, if water levels rise further, subsequent flooding is held within the flood control basin. The Eco-tank system integrates the flood control basin with the water tanks to provide better control over how increased water is controlled and to offer the best use of existing land.
