The 5 benefits and profits:
1. Decreases pumping station management expenses thanks to a short payback period: in less than 2.5 years
Without ROLAPAC: Up to five professional cleaningsessions per year may be required, causing management costs for a pumping station to rise significantly. This involves preparation by multiple departments of both the Water Authority and the Municipality, including the necessary (internal) permits. Coordination between several pumping stations is also required to handle downtime during maintenance. These operations often takes multiple working days, and the disposal of waste material is a logistical challenge.
With ROLAPAC: a single annual maintenance cycle is sufficient.
2. Sustainability: a far more sustainable solution than conventional cleaning methods with up to 90% CO₂ reductions
During conventional pumping station cleaning, multiple diesel-powered suction trucks are typically used. In addition to burning fossil fuels, these trucks extract wastewater containing fats and solids, which is then transported to an incineration facility. By reducing the number of cleaning operations from up to five per year to just one ROLAPAC maintenance inspection, the CO₂ footprint is reduced by up to 90%.
3. Mitigates pumpfailures and therewith reducing disturbance for residents near sewage pumping stations
Sewage pumping stations are often located in densely populated urban areas. Maintenance, cleaning and trooble shooting activities frequently cause inconvenience for homeowners and local residents. The ROLAPAC drastically reduces these disruptions.
4. Enhanced biogas production at the wastewater treatment plant
The ROLAPAC enables higher volumes of wastewater and fats to reach the treatment plant, where these fats can be converted into biogas, increasing the overall renewable energy output.
5. No longer dependent on the weather conditions to schedule maintenance
Planned maintenance on a sewage pumping station often cannot proceed if rainfall is expected, as the increased inflow of wastewater and stormwater prevents safe shutdown. In such cases, a new maintenance appointment must be scheduled. With the ROLAPAC, this dependency disappears.
Many pumping stations are operating at or beyond their maximum capacity. During heavy rainfall, a single malfunction can trigger a chain of reaction overload, resulting in discharges of oxygen-poor and contaminated water. Consequences may include fish mortality, foul odours, and in extreme cases, sewage backing up into residential toilets.
Municipalities and water authorities are responsible for ensuring 24/7 pumping station performance. With ROLAPAC, this becomes a realistic and reliable standard - as for now and in the future.
