Euro Try Tunnel sewage treatment plant with three-layer structural tank
Euro Try Tunnel is a
domestic sewage treatment plant with a drainage system manufactured by Euro-Plast.
The drainage treatment plant is equipped with modern EP100 infiltration tunnels. Such a system is characterised by higher efficiency compared to classic drainage.
The infiltration tunnels have a higher capacity than drainage pipes. The polyethylene tunnels increase the total absorption area by about three times compared to the traditional variant.
Importantly, the tunnels practically do not clog, which minimises maintenance work on the treatment plant, making it almost maintenance-free. This type of drainage guarantees long-term proper operation of the system. In addition, the large infiltration area allows a significant reduction in the drainage area, which reduces installation costs.
We offer wastewater treatment plants
for p.e. of 8 to 12 people.
There is a choice of versions for very good soil permeability. You can also order sets for good and medium soil permeability, which differ in the number of infiltration tunnels. For this, please contact us. The number of packages is selected according to the amount of wastewater and the permeability of the soil:
- soils with very good and good permeability (sand, gravel, gravel) - average of 4 packages per 1 p.e.
- soil with average permeability (clay sand) - average of 8 packages per 1 p.e.
In order to achieve a high efficiency of the treatment plant, we recommend the use of biopreparations , which act as a catalyst. This ensures that the treatment plant should not generate unpleasant odours. The wastewater treatment plant consists of
a Try settling tank with a capacity of 4,000 l and 5,000 l and an infiltration drain. Variants with
an inlet diameter of 160 mm are available. Detailed technical data can be found in the table.

The septic tank of the Euro Tunnel Try sewage treatment plant is a structural tank composed of a triple wall. This innovative construction of the settling tank is characterised by a very high resistance to mechanical damage. This ensures a high leak tightness of the structural tank. It is made of high-density HDPE polyethylene. The three-layer tank is resistant to adverse external conditions and to chemicals. It is also resistant to corrosive wastewater. The design and material of the tank guarantee long-term, failure-free operation. The risk of damage to the Try tank is minimal. The use of the tank can also be changed after many years, as can its foundation. This makes it a universal product for long-term operation.

When planning the placement of the sewage treatment plant, the manufacturer's installation recommendations must be followed. In addition to this, it is very important to
observe the minimum distances that are regulated by law. You will find detailed information on this in the
guide. We also encourage you to contact us.
The ST extension 20 cm - 50 cm high is compatible with the TRY sewage treatment plant tank.

The working principle of the treatment plant with infiltration tunnels is identical to the classic drainage variant. The wastewater treatment process consists of 2 stages:
Anaerobic treatment in a septic tank - pre-treatment of the wastewater with anaerobic bacteria;
Aerobic treatment in the drainage, occurring through the infiltration bed system;
