Underground septic tanks

All septic tanks are made using the rotational moulding method, which produces a very tight and extremely durable construction. We have tanks with capacities ranging from 1 m3 to 75 m3. The variety of models makes it possible to choose and install the tanks in any ground conditions. For heavy soils and in grounds with high groundwater levels, special flat tanks are dedicated. Please contact our advisors who will help you select a tank model to suit your needs.

As standard, the septic tanks are suitable for foundation in green areas. We also offer models for installation in vehicle traffic areas. The selection of a septic tank depends primarily on the number of regular inhabitants. In the classic calculation formula, the number of inhabitants should be taken into account and then multiplied by the standard consumption of wastewater per day (150 litres/person is assumed). The result will allow us to estimate the daily amount of wastewater generated. According to the standard, wastewater should not be stored for more than an average of 14 days - which is why 14 days is usually taken into account.
