Product description
The smallest variant of the plastic three-chamber septic tank with a volume of 3 m³ is suitable for couples or smaller families of up to 4 people for a family house or cottage.
The plastic three-chamber septic tank is a flow-through tank with an installed system of separation baffles, designed for the accumulation and partial treatment of wastewater from households.
By combining the NAUTILUS® three-chamber septic tank and a soil filter from our range, you can achieve a wastewater treatment efficiency of up to 95%, making it a full-fledged replacement for a wastewater treatment plant.
In addition, the construction of the plastic septic tank is self-supporting, so you do not need to encase it in concrete during installation, saving time and money.
The well-thought-out system of optional structural modifications allows the tank to be installed at such a depth that it can be easily connected to the sewer up to 110 cm below ground level.
Plastic lids with a UV filter including locks are included in the delivery.
