Roterra underground tanks have been developed to exceed the most demanding technical regulatory requirements, providing the best water storage solution on the market. We use only virgin materials that are suitable for clean water storage. Roterra tanks are available in standard capacities from 2,200L to 50,000 litres – larger volumes can be achieved by connecting several tanks together; so for example, we are able to connect 5 x 50,000L giving the customer 250,000 litres or more if required.
Manufactured in polyethylene, which is 100% recyclable and ribbed for reinforcement. Roto supply the Roterra rotomoulded tanks in one-piece up to 25,000 litre and 30,000 – 50,000L welded with telescopic neck for fast and easy installation. The tanks have a 600mm diameter plastic cover with a seal and four stainless steel screws, making them watertight. Inflow and outflow connections can be configured to the customers’ requirements from DN50 to DN400. The Roto tank wall thickness ranges from 8-14mm to give the tank its stiffness.
