Octagon septic flat tank

Underground septic tank with a flat, robust construction

Octagon is a flat underground tank for municipal sewage, septic tank or rainwater and for firefighting purposes. The Octagon tank has a lightweight, sturdy design which makes it easy to install. The tank has been patented for its unique flat design. Octagon has a very high mechanical strength, which allows for foundation in difficult groundwater conditions. Foundation in groundwater is also possible.

The tank has a 10-year warranty. Octagon is manufactured from pure polyethylene by rotational molding (rotomolding). It has no seams or welds. As a result, it is fully sealed and highly resistant to damage. Polyethylene is resistant to aggressive substances contained in wastewater. It does not corrode when exposed to the environment. The risk of unsealing is minimal. Octagon septic tank is a guarantee of safe use for many years.

We also offer a model of rainwater collection tank: Octagon rainwater tank.
