4000L (6 PE) septic tank in polyethylene - with pre-filter - GRAF

GRAF 4000 L ALL WATER TANK: a high-performance solution for a household of 5 to 6 people

Clean up your wastewater with this traditional, large-capacity septic tank.
By misuse of language, the septic tank is often confused with the all-water tank, but the former, which replaced it, allows for more complete and efficient treatment. It collects and pre-treats all domestic wastewater, whether it comes from toilets, the bathroom, or the kitchen.

This solution is particularly suitable for isolated homes where connection to the sewer system is impossible.

In order to guarantee the compliance of your project under SPANC control, we offer you here the GRAF 4000 L septic tank with Anaerobix pre-filter.

It ensures the retention of coarse materials thanks to its Anaerobix filter, their anaerobic fermentation and the decantation of non-liquefiable materials, for good long-term operation.
