A septic tank is an underground plastic tank that collects waste and sewage water from houses and other buildings.
In the individual chambers, separated by separating partitions, mechanical-biological treatment of wastewater takes place. In the first chamber, the solid parts of the waste remain, which settle to the bottom and gradually decompose. The purified water then flows into the second chamber, where further treatment takes place. The third chamber receives only clean water, free of solids.
After treatment, this water is either discharged into surface water (e.g. a stream or river) or percolated through the soil layers into groundwater. Septic tanks are usually used in areas where municipal sewerage is not available, for example in houses, cottages or holiday homes. They are also used where legislation allows for the septicisation of treated wastewater.
If you are not sure what type of septic tank is best for you, we will be happy to help you choose. Typically, septic tanks are supplied with an 800 mm diameter inlet stack and two manhole covers, one of which is vapour-tight. Both inlet and outlet pipes with a diameter of 160 mm are used.
We produce in two variants:
This element is designed to be placed in a trench under the underlying concrete slab. Once placed, it is backfilled with soil so that it is firmly anchored and can serve as a stable foundation. This makes it safe to walk over the element after the subsequent backfilling of the clearance area. In this way, the stability of the structure is ensured and at the same time comfortable handling of the element is made possible.
Designed to be installed in the trench under the underlying concrete slab, ensuring a firm anchorage. This element is suitable for concreting in taxiways as well as in environments with groundwater or clay subsoil, where its stability and resistance to external conditions is guaranteed. This allows it to be used in variable environments and ensures a reliable and durable result.
This construction combines the advantages of plastic and concrete, using plastic walls as protection for the concrete structure against the aggressiveness of wastewater and groundwater. This ensures maximum protection and durability of the tank. The plastic walls also serve as a support for the reinforcement of the future concrete in the intermediate shell, ensuring its stability and strength. This system ensures that the tank acquires the static properties of concrete tanks, which include load-bearing capacity and resistance to soil pressure and loads from travel. This combination of materials and technology provides the optimum solution for tanks with high stability and durability requirements.
