Drening Reflue is a modular system made from recycled plastic, designed for the construction of underground trenches intended for the dispersion of domestic wastewater, following primary clarification treatment (e.g., an Imhoff tank).
The solution is particularly suitable for residential settlements not connected to the sewer network, providing an efficient, durable, and easy-to-install system.
Sub-irrigation, or the dispersion of wastewater into the subsoil, represents one of the most established and reliable disposal methods. The operating principle is based on the gradual release of clarified effluent into a percolation bed composed of draining materials that replicate the soil’s natural microbiological processes.
Manufactured from high-performance recycled polypropylene and featuring a useful volume of 310 liters, Drening Reflue ensures high storage capacity and effective dispersion of effluent into the ground. Its semi-cylindrical structure and wide slotted surface promote uniform water distribution, improving infiltration efficiency.
The large dispersal surface of Drening Reflue elements enables homogeneous distribution of clarified wastewater into the soil, supporting natural filtration and microbiological purification processes.
The system is particularly suited for isolated homes, rural developments, and areas lacking sewer infrastructure, enabling safe and controlled disposal of pretreated domestic wastewater.
Integrated provisions for ventilation stacks ensure proper aeration of the system, preventing gas accumulation and limiting the spread of unpleasant odors.
Compared to conventionally used micro-slotted pipes, Drening Reflue offers a significantly greater dispersal surface, enhancing hydraulic performance and infiltration capacity.
The system geometry allows easier inspection, cleaning, and maintenance operations than linear pipe-based solutions, improving long-term reliability.
With a useful volume of 310 liters, the system maximizes temporary water storage capacity, contributing to a more consistent dispersion process.
Made from high-performance recycled polypropylene (PP), Drening Reflue ensures structural stability and a service life exceeding 50 years, even under demanding conditions.
The system promotes the return of water to the natural cycle, contributing to water resource protection. Drening Reflue is made from 100% recycled plastic and reduces the environmental impact of the installation.
