What if a single smart innovation could drastically reduce build-up fats, vibrations and CO2-emissions in sewage pumping station - and in the mean time, also generates savings? Sounds futuristic? Not with the ROLAPAC. This patented technology transforms a long-standing and persistent issue into a sustainable energy source.
In sewage pumping stations, a combination of fats, oils, organic material (FOG), and cleaning wipes, creates a notorious mixture. This mass clogs pipes and pumps, causes pump damage, generates odour and vibrations, and leads to expensive downtime.
With ROLAPAC these problems no longer exists.

More sustainable maintenance, less disruptions
Traditional cleaning with diesel-powered suction trucks is a burden for the environment and results in CO₂-intensive transport and waste processing.
Moreover, rainfall and adverse weather conditions frequently causes delays to scheduled maintenance, increasing the administrative workload and causing inconvenience for nearby residents.
With ROLAPAC, floating layers in pumping stations are reduced up to 90%. This drastically reduces the need for cleaning activities and enables municipalities and water authorities to manage their infrastructure more reliably, cost-effectively, and sustainably.
Innovative technology, practical results
With the installation of ROLAPAC, wastewater is no longer extracted exclusively via low intake points, but also through an additional opening at the top of the intake chamber. The floating layer is actively removed, eliminating the need for multiple maintenance shutdowns or specialist cleanings. In many cases, a single annual inspection is sufficient.
When a biogas installation is present at the wastewater treatment plant, ROLAPAC provides an additional benefit: energy-rich fat streams are removed more efficiently, resulting in higher biogas yields.
The risks of pump failures are also significantly reduced—or may even disappear entirely. Together, these advantages ensure a short payback period and long-term operational benefits.
Installation of the ROLAPAC requires just one working day and the system integrates seamlessly into the existing control system of the sewage pumping station.
Proven practices
- Ypenburg pumping station:
Previously known for weekly obstructions; now three years already without odour, vibrations, or any malfunctions.
“The pumping stations equipped with ROLAPAC are far more stable, efficient, and cost-effective to maintain. The system has proven itself for years,” says Farid, maintenance technician at Delfluent.
- Pumping station Scheveningen:
70% less debris accumulation and annual savings up to €75,000 - excluding environmental gains and personnel reductions.
Successful implementations
ROLAPAC has already been installed in, in the following sewage pumping stations:
- Scheveningen pumping station
- Ypenburg pumping station
- Leidschenveen pumping station
- Loosduinen pumping station
Additional projects are planned, and discussions are ongoing with various water authorities.
Financial and operational impact:
ROLAPAC delivers measurable savings across multiple categories:
- Reduced use of suction trucks and transport → lower fuel costs and CO₂ emissions
- Extended pump lifespan → reduced wear and maintenance
- Less failures → reduced problems with staffing and less disruptions
- Fat removal to digestion → higher sustainability scores and increased biogas productions
- More budget available for water authorities
- Positive contribution to climate and sustainability targets
