More about the tank

Octagon is the new series of flat tank. It is available in volumes from 4 to 21,5 m3. Light version is available in two capacities – 4 and 7,5 m3. The tanks might be used in different conditions, also hard once like low permeability soils or/and high ground water levels. Maximum ground coverage for Octagon Light is 40 cm and installation possible only in green area (light load). Octagon series might be used under car traffic area and maximum ground coverage is 150 cm. Octagon X-Line series is distinguished by ability to be used with ground coverage up to 200 cm and it also might be installed in truck load area. 

All Octagon tanks have got three connections (opening with rubber gasket and plug) which are in tank body. That localization allows to make easy pipe connections like inflow, outflow and technical opening (e.g. for pump cable etc.). The tanks have also got DN600 inspection hole. It makes an easy way to install pump or filter basket in the tank. Octagon tank has a flat design. It reduces time spent on assembly because of shallower pit. In the bottom part of the tank there is a dedicated place for making the welded connection for the battery connection of few Octagon tanks. Such battery connection creates a large retention capacity for a system consisting of more than one Octagon tank. 

Tanks are made in Poland and they have 10 years guarantee. Octagon Light series is available in garden kits, and Octagon series in both garden and home-garden kits. More information about that you can find in the download area in the bottom part of the website.
