CASE STUDY Silt Away hire aids hospital construction Before the construction of a new £300m hospital in the Midlands could reach an advanced stage, the company in charge of groundwork development sought a pumping arrangement that would separate silt from water before it was discharged into a nearby river. It was therefore imperative that suitable equipment was sought to ensure our customer could complete this process without incurring Environment Agency fines. Our solution was to provide the client with a suitable hire package that complied with strict industry regulations. These stipulate that companies who fail to remove contaminants from any water before it is transferred back into a natural watercourse face financial reprimands, in addition to a tarnished reputation. A Sykes Silt Away was therefore connected to one of our General Purpose unit that was already on site, driving groundwater through the tank before removing sediment and other impurities. The water passing through the Silt Away flushed any sediment and debris into a chamber via a Lamella platebox strainer. Our customer routinely emptied the compartment by placing retained solids into an available dumper which was collected and disposed of accordingly. By deploying this particular product at this location, we were able to clean thousands of gallons of silty water before returning it to an appropriate waterway nearby – thus enabling the construction scheme to proceed as planned. Sewage works extension assist by Sykes Pumps When overpumping solutions are required, Sykes Pumps can advise and deliver. When a Lancashire town was made the subject of a multi- million-pound development project, there was an immediate need for building a new sewage works to supersede the existing network. In order to connect a new sewer to the prevailing system, a temporary diversion had to be created which required the contractor to find a way of maintaining flows while new manholes were constructed. This was achieved with the assistance of Sykes Pumps, who proposed the hire of two Super Wispaset 200 units to help create a bypass system for the original sewer. The overpumping was then completed in two stages. The first of these saw a shorter bypass simply intercept the existing sewer approximately five metres away from the newly- created manhole and divert it through an existing line because the new additional sewage pipework had not been created. Once the new sewer was live, a stopper was placed along the original route to ensure heavier flows were safely controlled. The hired pumps were then repositioned adjacent to the stopping point, transporting discharged effluent at ground level. Failure to supply the correct equipment would have left a vast area flooded with unscreened waste, but our expertise and swift reaction averted a potential environmental disaster whilst a modern sewage network was constructed. The customer was delighted with the overpumping arrangement which saw one of Sykes' local technicians quickly calculate the required specification and deploy the best solution possible.
