PE Septic Tanks – Reliable Wastewater Collection for Every Requirement
ROTO Septic Tanks – Efficient Solutions for Decentralized Wastewater Disposal.
Roseptic septic tanks are designed for the safe collection and preliminary treatment of domestic wastewater.
Configured as multi-chamber systems, they effectively separate solids and floating matter, thereby establishing the foundation for subsequent wastewater treatment in a sewage treatment plant.
Their monolithic polyethylene construction ensures absolute leak-tightness and high resistance to aggressive wastewater. At the same time, their low weight enables rapid installation without the need for heavy construction machinery.
ROTO Septic Tanks for Every Installation Scenario:
- Single-family homes without a sewer connection
- Multi-family homes and residential complexes
- Commercial properties
- Remote locations or sites with limited infrastructure

FAQ
As a guideline, approximately 150 liters per person per day is assumed. The exact sizing depends on the number of users and the usage patterns.
No, septic tanks are designed exclusively for domestic wastewater. Rainwater must not be connected.
That depends on the volume and usage. Larger systems require significantly longer emptying intervals.
In principle, yes. Thanks to the low weight of the PE containers, installation is possible even under difficult access conditions.
