Roth Multi Tanks (RMT) can be used for potable water, pump, holding, rainwater or septic tanks. This is possible due to its special construction: an inner layer of FDA approved virgin HDPE; two inside layers of PE for improved stability; and one outer layer of black and UV-stabilized PE. At Corkum’s Pipe & Culvert Inc., we are proud to put these excellent products at your disposal. Don’t hesitate to contact us if you have any questions!
