Twinbloc tank 3500L shaft/cover

Roth Twinbloc® sealed tank
Thanks to its low double-wall structure, the tank is especially suitable for demanding sites that require a shallow installation depth. Its design reduces excavation costs compared to traditional tanks, and only two anchor straps are needed for anchoring. The tanks can also be installed in locations with a high groundwater level. They are lightweight and equipped with handles that make installation easier. The tanks are manufactured from PE-HD plastic using blow molding technology as a single piece. Since the method requires no seams, the result is a cost-effective and consistent-quality product.
Country of manufacture: Germany.
We grant a 10-year warranty on Roth Twinbloc® tanks.

Roth Twinbloc® sealed tanks are equipped with a telescopic DN200 emptying shaft with a durable plastic cover. Multiple tanks can easily be connected in series using 110 mm underground sewer pipes and a connection kit.
