CASE STUDY Major UK retail centre turns to Sykes for over-pumping configuration Sykes Pumps Hire was recently contacted by an Essex-based con- struction company seeking an effective pumping solution to stop water from a nearby lake stalling progress on site. The customer in question had a very large lake next to their main working area. During the digging stage of the construction works, water from the lake was seeping through to the site as the excava- tion was so deep. This caused issues for workers as they couldn't begin laying a concrete base until the area was completely dry. As a result, Sykes Pumps were drafted in to remove the nuisance water from the affected area and pump it back into the lake while removing any sediment, silt and other abrasives. This process ensured the discharged water was free of possible contaminants before being reintroduced back to the lake. After conducting a site survey, their pump specialists deployed and installed a diesel driven 8" Super Silent pump accompanied by a set- tlement tank, allowing the sediment and solids to be collected and con- tained within the unit. By providing the client with a settlement tank they were able to prevent the lake from being pol- luted and therefore avoided incur- ring any fines due to negligent practice. The customer was extremely pleased with the pump hire package that was provided only hours after the enquiry, as it was crucial in allowing work to begin while ensuring the dis- charged water was successfully cleansed. Sykes tailor unique pump hire installation for multimillion pound scheme When a £300 million development programme in the North West required pumping assistance, Sykes were called in to aid the Far- rans and Roadbridge joint venture which involved a new pipeline being installed. The scheme saw more than 100km of pipes being laid and relined as part of the net- work serving the West Cumbria region. With the construction in its infancy, Sykes Pumps was asked to provide a hire solution to remove groundwater from the job site. Much of the pipeline was config- ured to take water from Thirlmere Reservoir which required the client to tunnel underneath the River Greta. A pumping arrangement was therefore required to direct run-off water into a stream several hundred metres away, enabling work to begin. The customer was also obli- gated to ensure any discharged water was treated before it could rejoin the watercourse, with environ- mental regulations requiring this. Sykes Pumps installed three PX22 8" submersible units at the lagoon in which water was being collected, with connected hoses running 150 metres uphill to a road crossing. A separate PX22 sub- mersible pump was used at a sec- ond lagoon, with the hoses from the two arrangements connected via a Y-piece to enable water from both lagoons to pass beneath the road. Once the water had passed through the Y-piece, the set-up reverted to four runs of 8" hose and the water pumped through manifolds to the four Sykes Silt Away separation systems before exiting into man-made soaka- ways. From there, the water entered a nearby beck having been removed from the con- struction area and cleansed. The installation, although tai- lored to the client's unique require- ments, is a typical example of Sykes Pumps' ability to devise and imple- ment a bespoke solution quickly to ensure a wider project can proceed as planned.
