For example a 10,000 litre plastic tank (12 tonne) which is provided with a pump. This system enables liquids to be easily added into any mixer wagon. These tanks do not degrade like steel tanks and are semi-opaque allowing the level of liquid to be seen at all times. The tanks are 2.7m in diameter and must be sited on a solid, level base. For customers requiring a larger storage volume, tanks can be linked together and piped into a single pump. Steel molasses tanks are also available for purchase on request.
