Manhole extension collar for IMO septic tanks, 30 cm

Description

IMO septic tank manhole extension, 30 cm

The 30 cm extension collar is compatible only with IMO (ECO Imhoff) septic tanks. It raises the manhole to make access easier for inspection, maintenance and emptying after underground installation.

When do you need an extension?

When the landscaping requires the access point to be raised, choose the extension height based on the final cover level and the installation conditions of the septic tank. The extension is sold separately from the tank.

• Nominal height: 30 cm.
• Compatibility: IMO (ECO Imhoff) septic tanks only.
• Use: raising the manhole.
• The extension does not change the maximum burial depth or the permitted loads for the septic tank.

Compatible IMO septic tanks

Choose the right septic tank for your project: ECO Imhoff 4, ECO Imhoff 6 or ECO Imhoff 10. The extension can also be ordered with an IMO septic tank package with installation, depending on the needs of the job.

Installation and access

Keep access to the cover for inspection and emptying. Installation and sealing are carried out according to the manufacturer's instructions; using the extension does not make the cover load-bearing for vehicles.
