The MONOBLOCK is a new-generation, all-in-one non-electric sewage treatment system from BIOROCK®, combining a primary tank and treatment unit within a single, compact tank. Designed for simplicity and reliability, it provides efficient wastewater treatment with no electricity, no moving parts, and minimal maintenance.
The MONOBLOCK is available in capacities of 8 people (8 PE) with a tank capacity of 3000 L or 6PE.
This self-contained system is ideal for compact plots, off-grid homes, and low-occupancy properties, offering a simple, discreet, and odour-free wastewater treatment solution. Optional versions are available with an integrated discharge pump for sites requiring powered outflow.
Key Features
All-in-one single tank design – primary settlement and treatment in one compact unit.
Non-electric system – no energy required for standard operation.
No moving parts – silent, reliable, and low-maintenance.
Optional integrated discharge pump – electricity required only for pumped versions.
Pedestrian-loading lid – safe and easy access.
Ideal for off-grid homes, small plots, and eco-friendly developments.
Compact and discreet – fits tight spaces without compromising aesthetics.
The BIOCROCK non-electrical treatment process:
Step 1 : Primary Tank
The Primary Tank clarifies the raw sewage by dividing fats, oils, greases and organic solids. The sewage then passes through an effluent filter, before discharging into the BIOROCK reactor.
Step 2 : BIOREACTOR
The Bioreactor purifies further the pretreated wastewater with a biological process. To naturally treat the wastewater, our systems use our unique BIOROCK Media, an exclusive and very efficient carrier material for bacteria.
Step 3 : Discharge
Depending on the ground type, effluent will be discharged by gravity, or by a pump.
