When space is tight stormPANEL tanks are ideal for existing and new homes. The tanks are designed to not be seen and the ease of handling was part of the design process from the start. Devan stormPANEL tanks are manufactured from the highest quality polyethylene available which is ideally suited to our moulding technique, giving long life and trouble-free service. The material is certified to AS/NZS4766:2006, AS/ NZS4020:2005, and AS/NZS 2070 so are suitable for potable water.
