Reliable operation when the storm comes
Weather is unpredictable, your trashrakes shouldn’t be
From seasonal runoff to 100-year storms – open channel trash rakes must operate dependably. A flood control plan is often the only thing between a weather event and the loss of life and property. This makes reliability the key issue for automatic trash rakes/bar screen systems because:
- Trash rakes are the first line of defense, they are critical to keeping pumps operating; moving water to prevent flooding; and to meeting accountabilities for public and community protection.
- No one can predict what will find its way into an open channel, trash rakes must be designed to minimize jamming or binding and adapt to debris and flow variations.
- Trash rakes often sit idle for extended periods of time between weather events, the technology must be resistant to binding and corrosion to assure the ability to start on command. Rakes must function reliably during the brunt of any event without fail.
- When the storm hits with high winds, high flows and volumes, trash rakes must work absolutely: without long cycle times; without cables to tangle; and without chains and sprockets that foul underwater.
- Underwater maintenance is expensive and inconvenient, it is important that trash rake maintenance be such that it can be performed from the deck. Fouling is most likely to occur when a storm hits—causing performance issues at a time when divers cannot be safely sent into the water to correct them.
Duperon Corporation’s roots are deep in the flood control and stormwater sector. Prior to supplying trash rakes, founder Terry Duperon was an inventor and manufacturer of pumps. He saw that his customers had a problem in storm events – their pumps would shut down to avoid cavitation when water levels dropped from fast-moving debris damming their trash racks. These pumps were needed to protect communities from flooding. By looking beyond the pumps to the source of the problem, Terry began inventing screening technologies that provided consistent pump protection, that were groundbreakingly simple, cost-effective and easy to own.
