Water storage tank

in-groundin high-density polyethylene

These tanks are manufactured in a special kind of HDPE with a higher rigidity and density to be resistant to the stored contents and the underground pressure that the tank may encounter. They are all provided with the necessary parts to connect a standard burner e.g. for heating purposes. The tank has been designed for underground installation (check installation procedures) and is provided with large strengthening ribs (to be resistant to ground pressure) and a welded liquid-tight top-shaft. The riser is provided with a special transit part (inner diameter 50mm / outer diameter 63 mm) on which (using special glue) a 50 or 63 mm PVC conduit can be connected. This ensures liquid-tight passage of the burner's tubes into the tank. The cover is provided with 5 connections of 2F to guarantee the liquid-density. A combined electronic overfill sensor with suction and return, an aerator and fill-cap as well as an electronic capacity-meter TANKALERT-type are already installed. In our technical department, every tank has been pressure-tested with pressure for leakage. These tanks are available in both 2.950 litres and 4.950 litres
