Roseptic Septic Tank: Multi-Chamber PE System for Municipal Wastewater
The Roseptic is a monolithic, absolutely watertight PE septic tank designed for the secure collection of domestic wastewater. Developed as a multi-chamber system, it serves as the foundation for virtually any wastewater treatment process and ensures the effective separation of solids and floating matter prior to discharge into a treatment plant.
Typical Applications:
- Collection of municipal/domestic wastewater
- Preparation for further treatment in municipal wastewater treatment plants
- Use in areas without a direct sewer connection
- Use as a sealed holding tank only where a technical connection is not feasible (e.g., in remote locations)
Roseptic in Detail.
The standard-sized Roseptic offers a compact and flexible solution for the collection and preliminary clarification of domestic wastewater. Designed as a multi-chamber tank, the system reliably separates settleable solids and floating matter, thereby establishing the foundation for subsequent wastewater treatment.
Thanks to its monolithic polyethylene construction, the tank is completely watertight and resistant to chemically contaminated wastewater. At the same time, its comparatively low weight enables quick and uncomplicated installation—even on properties with restricted access.
Its various widths and volume options make the Roseptic highly adaptable for single-family homes, smaller multi-family dwellings, or decentralized drainage solutions. Furthermore, the choice between a two-chamber and a three-chamber system allows for a design tailored specifically to requirements, depending on the intensity of use.
