Dual Auger System
A solution to “flushable” wipes
An alternative to grinders and chopper pumps in the collection system and plant headworks
Wipes wreak havoc
in collection systems and downstream treatment when not removed… Imagine removing wipes before a small problem becomes a big problem.
Operators no longer have to compromise between manually cleaning clogged pumps or using maintenance-intensive grinders that send debris downstream only to re-weave and become problematic again. Our design uses three proven Duperon technologies to capture and remove rags and other pump-fouling debris while keeping organics in the collection system.
Introducing the Duperon Dual Auger System
a simple and compact screen that removes the majority of wipes and rags in the collection system. By removing non-dissolvable solids at (or near) the point they enter the collection system, the Dual Auger System restores systemwide integrity by allowing them to operate as they were designed, unimpeded by wipes.
… all with the simplicity and reliability that you have come to expect from Duperon innovation.
Applications:
- Wetwells
- Manholes
- Nursing homes
- Hospitals
- Prisons
- Septage receiving
- Campgrounds
- Truck stops
- Industrial applications
- Municipal headworks
- Package plants

The Duperon®
Dual Auger System
Drastically reduces clogged pumps
Simple 5 in 1 System
Capture, dewater, compact, store and convey screenings all with one piece of equipment
Addresses the problem at its source
Deploy at high-ragging sites experiencing pump clogging to remove problematic debris before downstream equipment can be impacted
Compact footprint
Can be installed in manhole & wetwell applications as small as 17 inches
Eliminates emergency maintenance
Replaces it with planned (scheduled) and infrequent pickups
Description
The Dual Auger System is positioned in a wet well or manhole to catch the falling waste stream from the inlet pipe. The screening unit is comprised of two vertical counter-rotating augers driven by an electric motor. The motor is completely sealed in the upper housing. The Dual Auger System is fully submersible.
There is an overflow bypass opening ahead of the screening unit. The vertical bar screen has a .71 inch bar opening with other size options available. As screenings are captured, a discharge chute extends vertically to compact, dewater, lift, and store debris, without additional augers required. The solids are held in the chute or discharged into a bin, fully contained for odor control and aesthetics. Debris management is simple, with planned and infrequent pickups to dispose of solids.

| Standard Controls | Stand alone weatherproof VFD, padlock security and speed control. Custom panel options are available. |
| Installation | Install inlet pipe adapter with four (4) ½ inch concrete anchors. Use a small crane or portable gantry to lower unit down. Align trough to pipe adapter. Support discharge chute at deck level with four (4) ½ inch concrete anchors. No guides or rails required. |
Key Features
The Dual Auger System builds on three proven Duperon technologies:
- Positive displacement dual augers continuously clean the inlet by capturing and lifting solids
- Brushless self-cleaning eliminates maintenance
- Discharge extension chute conveys compacted debris without full length augers.
Built-in Bypass eliminates sewer backups during power outages
