During 2018 Northumbrian Water installed two new DERAGGER+ units. In Sunny Brow (Crow) they delivered an estimated cost saving of £12,000 per year. This station used to frequently rag and had been run with proactive weekly lift & clean visits in order to keep on top of the ragging. Once the DERAGGER was activated, these could be scaled back as they were no longer required.
The Fens (Hartlepool) was referred to by staff as a “non blocker”, however with the DERAGGER installed here it delivered efficiency savings of 20.24% on one pump, and 8.75% on the other pump. At this site we also tracked a significantly more stable current with the DERAGGER, meaning a strong likelihood that the DERAGGER will also extend pump life.
