Octagon rainwater flat tank

Underground rainwater tank with a flat, robust construction

The Octagon is a flat underground tank for collecting rainwater, municipal sewage or water for firefighting purposes. The Octagon tank has a lightweight and durable construction which contributes to the ease of installation. The tank has been patented for its unique construction. The Octagon has a high mechanical strength, which makes it suitable for foundation in difficult ground conditions and groundwater. The tank comes with a 10-year warranty. The Octagon is manufactured from pure polyethylene using the rotomoulding method.
