Septic tank 4000 L

A 4000 L septic tank is available for use above or below ground. It features a service hatch and also comes with an outlet pipe option. NFP fibreglass septic tanks conform to AS/NZS 1546 requirements.

The tank can be fitted with a bio filter, baffles, inlet pipes, outlet pipes, inspection hatches and a mushroom vent as needed, so it arrives set up for your site. Where the tank is buried, the vault hole has to drain properly, which matters most in heavy soils and high rainfall country.

These tanks are not designed to withstand additional surcharge pressures, live loads such as vehicles parked on or near them, nearby buildings, or lateral earth pressure from nearby embankments, structures or walls. We accept no liability if these design limitations are not met.
