Thome flat storage tank Thome Twinbloc- innovative design

Thanks to its excellent shape and extremely low-profile design, the Thome Twinbloc low-profile storage unit offers considerable advantages in terms of installation. Compared to traditional rainwater tanks, the excavation work required for the pit can be reduced by up to 40 %. The shallow installation depth even enables installation at sites with a very high groundwater level. The two parallel cylinders provide additional stability. Two tank chambers with smaller diameters are significantly more stable than a single chamber with a large diameter. As a result, the surface above can be utilised, e.g. by cars.

The Thome Twinbloc is available in 1500, 3500 litre and 5000 litre versions. Taken in conjunction with the matching accessories, this means Thome is able to offer a complete system for professional rainwater applications. The PE tanks are stable in the ground and can be driven over by cars. A dome shaft is supplied with every tank. This is fully ***ed into the tank on delivery and can be adapted in each case to the installation depth of the tank. Two opposing empty conduit connecting pieces can be used to connect the supply lines. The perfectly matched components help make installation both quick and easy. A flexible approach can be adopted to suit individual requirements and different conditions on the ground, making it possible to offer the right solution for almost any application. All it takes to connect a number of Thome low-profile rainwater storage units together is a DN 100 connecting line.
