In-ground tank TERRA

rainwater

With Mall Terra rainwater storage tank, the combined usage and percolation of water is not only easy, but also attractive, as this system is equipped with an integrated biological soil zone. In most cases, the system fulfils the criteria which mean that an operating licence is not required. The rainwater is cleaned by the soil filter which consists of a special substrate. The substrate allows for robust planting, is not sensitive to blockages and prevents the water from discolouring. The filtered water is collected in a submerged drainage system, and passes through irrigation openings into the storage space.
