BIOROCK sewage treatment solution serving a group of houses at a small rural community in Sweden




BIOROCK technology serving a group of houses at a small rural community. Below-ground installation of a MULTIROCK composed of 3 X ECOROCK-5000 residential sewage treatment units discharging to a nearby lake.


The community may have significant fluctuation in residents throughout the year depending on the season. Hence the system needs to cope with this fluctuation in seasonality. The BIOROCK MULTIROCK residential sewage water solution is ideally suited for this application for multiple reasons:

  • non-electric operation,
  • low maintenance
  • high quality of treated effluent.

The MULTIROCK sewage water treatment plant was selected by residents together with the contratcor as the most suitable for this project.
