Among the reasons our customers choose our products: Ecofosa septic tanks, valued for quick installation, easy mobility and cost efficiency; G/V monoblock treatment plants, known for their strength and low weight; grease and heavy-particle separators, chosen for their eco-friendly design and recyclable materials; or septic tanks, built to withstand temperature fluctuations. In addition, mini treatment plants (biological septic tanks) offer protection against weather, corrosive substances and acids, and are not affected by mould or lichen. These products are made even more accessible by promotional prices available.
The reliability of our products is guaranteed by the manufacturers we represent, with a 2-year warranty against manufacturing defects and 30 years against corrosion. What is more, if a fault occurs, the product is replaced with a new one. Throughout the warranty period, our technicians monitor equipment performance and are available for any technical or usage questions, providing prompt, specialist support.
A septic tank is an eco-friendly and efficient solution for managing domestic wastewater, ideal for homes in areas without access to the mains sewer network. Made from high-density polyethylene (HDPE), it is designed to withstand extreme temperatures, from -60°C to +80°C, ensuring durability and optimal operation in any climate.
It is a more cost-effective system than the traditional concrete one, in terms of purchase, maintenance and installation costs.
A grease separator is chosen based on the volume of wastewater generated, the type of activity and the grease load. The ECO DIS 40 model is suitable for restaurants, canteens, hotels, catering units and other food-industry premises where grease and settleable particles must be separated efficiently from wastewater.
No. ECO DIS 40 works by gravity separation and needs no power supply, which makes it easy to operate and cost-effective.
A pit is dug for the tank, plus three parallel trenches for the drainage system (they can be dug by hand or with machinery). The pipe from the house is connected to the tank inlet, and the tank outlet is connected to a drainage system in the ground.
IMPORTANT: The tank must be filled with water before it is backfilled!
Before explaining how an eco-friendly (biological) septic tank works, it is important to know the components of the system:
Inner chamber (digestion–fermentation) - here, without oxygen, a bacterial culture forms (the anaerobic decomposition process), which breaks down the matter and extracts its water content.
Outer chamber (settling) – this chamber settles the polluting sludge produced by digestion.
Biogas vent - venting is recommended through a 1-inch nipple connected to the vent system at the top of the tank (threaded hole with cap)
Inspection/emptying access - the tank has a threaded inspection cover on top, which is also used for emptying.
Dig 1, 2 or 3 parallel trenches (depending on the tank capacity and the space available). Use 110 mm or larger perforated drainage pipe, connected with a T-fitting to the tank outlet, then lay the pipe along the parallel trenches.
IMPORTANT: For best performance, keep a slight fall from the house to the tank and from the tank to the drainage system (about 2–3%).
The bacterial culture (bioactivator) is added before first use. It speeds up the formation of the bacterial culture.

P.E. = population equivalent. In line with standard EN 12566-3, the flow is calculated from an average consumption of about 200 litres per person per day. So an ECO6 septic tank is sized for 6 P.E. Its maximum capacity is 6 P.E. × 200 litres = 1,200 litres of domestic wastewater per day.
An estimated daily flow is calculated from the washing capacity or the number of wash bays. The oil and hydrocarbon separator is sized according to this flow. Depending on the discharge area, it can be a simple model that also acts as a sand trap, or one with a coalescing filter that raises separator efficiency to up to 98%.
An Imhoff septic tank is emptied every 2–3 years (under normal operating conditions). This period can be longer if the tank is not used intensively, or shorter if it is used beyond its rated capacity.
If vehicles will drive over the tank, a concrete chamber must be built around the septic tank and fitted with a load-bearing cover. The concrete chamber and load-bearing cover will carry the full weight.
The bioactivator is added when you commission the septic tank. In principle, it is added only once, at the start of use. At the first emptying, 90–95% of the tank contents are removed, and the remaining 5% of sludge at the bottom helps the bacterial population recover.
No. Anaerobic fermentation inside the tank releases heat. The water in the drain will not freeze, because drains must be buried below the frost line (90–100 cm).
The septic tank is emptied through the inspection cover on top of the tank.
No. Water from the septic tank must be discharged into the ground through a drainage system.
To discharge into a river or watercourse, you need an FA (activated sludge) treatment unit. It is installed after the septic tank (water flows from the tank into the FA unit, then into the river or watercourse). With this septic tank + FA system, the treated water meets NTPA-001 (the Romanian standard for discharging domestic wastewater into rivers or watercourses).
Drain length depends on the number of people and the soil type. If the soil is permeable, allow 5 m of pipe per person (e.g. for the 4-person ECOIMO4 tank, the drain should be at least 20 m). If the soil has poor permeability (clay), allow 7–8 m of pipe per person; for a 4-person tank, the drain should then be at least 30 m.
