First UK installation of Chopper pump combination halts ragging problem at Scottish Water’s Chapelknowe Sewage Pumping Station

Posted: Tuesday 11th August 2009

The first ever UK installation of the new Flygt Chopper Pump, supplied by ITT Water & Wastewater, the UK’s leading water and wastewater specialist, has provided a complete solution to a major ragging problem at a sewage pumping station in Glasgow, Scotland.

ITT Water & Wastewater’s service centre in Livingston was contacted by Scottish Water’s on-site operations team at the Chapelknowe pumping station in Glasgow. They reported that high levels of heavy rag entering the station were causing pump blockages three or four times per week, causing tankering and operational costs to rise to an unacceptable level.

ITT Water & Wastewater’s Service Sales Engineer Derek Lourie attended the site to assess the situation and propose a solution to eliminate the blockage problems.

Having carried out a number of system checks, ITT Water & Wastewater recommended the installation of an 11kW Flygt Chopper Pump, which has been specifically developed for applications involving high levels of ragging. This was supplied to Scottish Water on a ‘try before you buy’ basis, allowing them to trial the product without any upfront capital commitment.

In the six months since installation, Chapelknowe has not experienced a single blockage while a recent service inspection showed almost no wear on the hydraulic parts, clearly demonstrating the durability of this product.

Indeed, Scottish Water has been so impressed with the Flygt Chopper Pump’s performance that two further models have been ordered as part of an overall refurbishment of the Chapelknowe pumping station.

Chris Stewart, ITT Water & Wastewater’s Business Development Manager for Scotland, said: “Scottish Water had already made a commitment to refurbish the entire pumping station with non-Flygt pumps. It soon became apparent that the Flygt chopper pump was making a considerable difference, so the decision was made to change the renovation designs and incorporate Flygt products instead.”

David Thomson, Engineering & Maintenance Team Leader for Scottish Water, commented: “The Flygt Chopper Pump has solved a major issue at Chapelknowe where the number and scale of blockages were becoming highly problematical operationally and financially.

“It’s a testament to the performance of the product in this very demanding situation that we have now specified it for two other locations within the NITH Area of Scottish Water additional to the refurbishment of our Chapelknowe Pumping Station .”
