 | | SPP HELPS CARDIFF WEATHER THE STORMS | | | SPP Pumps Ltd | | 23/07/2008 | | | SPP Pumps have just completed a major overhaul and upgrade of Sewage Water Pumps and Valves at the Cardiff Western Pumping Station in Penarth Road – which could be seen as a valuable contribution to the safety of the area with weather patterns becoming less predictable.
The project included removal, installation and commissioning of three SPP EK14 and two SPP EK12 Storm Water Pumps, plus the overhaul and test of five Non-return Valves. It was essential to overhaul the valves in addition to the pumps to prevent re-circulation within the chamber thus reducing the benefits of the overhaul and upgrade.
All of the pumps were performance tested at SPP, the only major test facility in the South West, before re-installation.
This Welsh Water pumping facility receives gravity-fed flows from the western catchment of Cardiff and pumped flows from stations at Trelai Park, Ferry Road and The Marl. It replaced the original Victorian pumping station, which has now been converted into an antiques market, in the early 70s and the pumps date back to this installation. The main pumping station comprises pass forward pumps and storm lift pumps. All flows enter an open topped rectangular wet well, and storm flows weir over into a channel which feeds the storm pumps.
The storm tank itself is 20m diameter by 33m deep. It is equipped with three storm return pumps, two mixing pumps and a single tank drain down pump, which was also overhauled by SPP. Once the storm tank is full it spills to the River Ely by gravity – but this discharge must be within designated flow rates.
Jeff Hudd of Imtech Process, the project contractors commented, “SPP pumps were originally specified because of their reliability and long life, and have proved invaluable over the years for their “non clogging” characteristics. The overhaul was necessary to ensure reliable performance to cope with predicted weather conditions over the next ten years. If the facility failed to function effectively, the resulting impact on the local environment could lead to sanctions and heavy penalties being applied. I am pleased to say that, after the overhaul, the pumps are now performing to a standard to achieve the required station output.” | |
