Roth MultiTank®

The Roth MultiTank® is the first tank of its kind. It can be used for water cistern, pump, holding, rainwater, or septic tank. This is possible due to its special construction of an inner layer of FDA approved virgin HDPE, two inside layers of PE for improved stability, plus one outer layer of black and UV-stabilized PE. Not only is it special in terms of its construction, but it also has the best warranty the industry has to offer: lifetime corrosion protection and 5 years of labor insurance coverage (see warranty for more details).

When used as a Potable Water Cistern, also known as a Rainwater Cistern tank, it is used for storing rainwater collected from a roof or other catchment area. Cisterns are sometimes used for storing hauled water but are usually used as a supplement to other water sources. Cisterns are very useful when the regular source of water for a farm or rural home becomes low in dry periods of the year.
