Domestic Wastewater Guidance and Advice

Wastewater is a term that is used to describe waste material. That includes industrial liquid waste and sewage waste which is collected in towns and urban areas and treated at (UWWTPs) urban wastewater treatment plants, as well as sewage that comes from single houses or small communities in the countryside that is treated on-site in either septic tanks or individual wastewater treatment systems (domestic wastewater treatment systems – DWWTS).

Wastewaters from single houses in the countryside that are not connected to sewers should be generally treated on-site by septic tank systems or individual domestic wastewater treatment systems.

Non energy wastewater treatment systems for small municipalities and communities

A case study – The non-electricity  wastewater treatment plant ClearFox nature for municipal wastewater in a concrete tank

domestic wastewater treatment in concrete

sewage treatment in a concrete tank

We offer our ClearFox nature with the year 2017 for smaller agglomerations, municipalities up to 75 p.e. (people equivalent)
Operation cost for energy or power are zero

In addition, the effort for service and maintenance is much more less as in standard domestic wastewater systems. The domestic wastewater treatment plant, as the name “nature” already says, works on the natural principle of gravitation and air circulation. The technology, which is very successful in the size range up to 32 inhabitants (EN 12566-3 tested) and also internationally, is built into a rectangular concave. Standard components of the smaller variant are partially re-designed without leaving the active principle.

The design is based on the small sewage treatment plant in consultation with independent institutes and experts.

This domestic wastewater treatment plant is intended for smaller municipalities, as well as for holiday resorts, campgrounds and mountain shelters. Basically wherever there is no current connection or is required, or a low-maintenance, robust operation is required. Furthermore, this domestic wastewater treatment plant operates completely autonomously in almost all climatic zones. From hot Africa to cold Scandinavia, the electricity-free sewage treatment plant can be used. Provided in very cold regions is only the frost-free and professional earth building.


  • Non-electric sewage treatment plant –> No electricity costs
  • No wear parts –> Low consequential costs
  • Stable concrete container –> For large plants in the future also in concrete containers
  • Completely pre-assembled –> Just connect to the building site, finished
  • The exchange of wearing parts was limited to a minimum –> High-quality biofilm technology, Even when the load is fluctuating, the sewage treatment plant achieves the required flow parameters

As with our small sewage treatment plant version, the ClearFox nature in the concrete container, the domestic wastewater treatment system also offers the possibility of retrofitting behind existing septic tanks. If, on the other hand, pre-clarification is already available, we can calculate and adapt the biology plants according to local requirements.

If the system cannot be installed with the required slope of 1.50m from the inlet to the drain, there is also the option of connecting a pump shaft

This is also due to the cost of just € 1 per inhabitant per year. Do you have questions about the non-energy ClearFox nature sewage treatment plant in the concrete tank?
