ECO IMHOFF
2.190,00 RON
The ECO IMHOFF 4 septic tank is an efficient solution for pre-treating domestic wastewater, designed for small and medium households. Made from high-density polyethylene, it provides durability, watertightness and safe operation over time. Its internal compartments separate the solids and discharge the pre-treated water in a controlled way to drainage, making it ideal for areas without sewers.
An efficient solution for treating domestic wastewater
The ECO IMHOFF 4 septic tank, with a usable volume of 690 litres, is a practical and efficient solution for the primary treatment of domestic wastewater, suitable for permanently occupied homes, small households or properties without access to the public sewer network. Thanks to its Imhoff-type pre-treatment system, it separates solids efficiently and supports stable operation over time.
It works through natural settling and anaerobic digestion, making it simple to run with low long-term costs.
The tank is a one-piece unit made from high-density polyethylene (HDPE), a material resistant to corrosion, temperature changes and mechanical stress. Its watertight construction guarantees a long service life and safe operation in various installation conditions.
✅ simple operation and low costs
✅ efficient separation of solids
✅ watertight one-piece construction
✅ high resistance to corrosion and mechanical shocks
✅ easy integration with drainage and infiltration systems
✅ simple maintenance and long-term durability
The ECO IMHOFF 4 septic tank works on the principle of gravity separation and anaerobic digestion. Wastewater enters the tank, where solid particles settle in the lower compartment and organic matter is broken down naturally. The pre-treated water is discharged in a controlled way to the drainage or infiltration system.
The ECO IMHOFF 4 septic tank is recommended for:
permanently occupied family homes
households with 2–4 users
holiday homes and remote properties
areas without access to the sewer network
The tank is installed on a levelled sand bed, following the technical instructions, and connected to the drainage or infiltration system according to the site layout and project requirements.
To maintain performance, periodic emptying is recommended, depending on the level of use.
