摘要

Water reservoir constituted of vertical pipes (11) arranged between upper and lower panels (1) which have been connected to a roof and a bottom. One ore more of the pipes can also constitute overflow outlet cleaning connections and a connection to the ambient air. Corresponding openings can be provided in the roof panels (1). A combined outlet/inlet (13) communicates with the water reservoir at its bottom level. Due to the vertical arrangement of the pipes the water reservoir can take a considerable vertical load. Around the sides of the water reservoir fabric or plastic sheets or nets or a combination thereof is suitably placed in order to prevent soil and filling around the reservoir to penetrate into this.
