www.wwtonline.co.uk | WWT | JUNE 2016 | 19 Project focus Pumps and pumping systems Pumps critical to River Clyde flood prevention scheme Project focus K SB and Ferrier Pumps Ltd recently continued their long standing partnership working on a flood prevention scheme for Renfrewshire Council. This involved planning and collaboration on the front end design, pump testing, supply, installation and commissioning of all the pumps and ancillary equipment. The project involved KSB supplying four variable ● North Renfrew scheme to protect 300 homes and businesses ● Protection offered against 1-in-200-year flood event ● Pumping station guards against tidal flooding from River Clyde The flood prevention scheme will protect more than 300 homes and businesses in North Renfrew and comprises a 3m high embankment and a new underground pumping station at the Mill Burn at Fingal Road. The embankment, which runs westward for 1km from Ferry Road, provides a barrier against direct flooding from the Clyde. The pumping station containing KSB pumps will ensure that tidal surges on the Clyde do not cause the Mill Burn to overflow and flood local properties. The new scheme will see an end to periodic flooding which has affected many homes and businesses in the area at least once a year. The combination of tidal surges and overflow from the burn has created flooding problems in the north end of Renfrew since the area was reclaimed from the river 300 years ago. The pumping station provides a capacity of 5.5m 3 /s to provide standard protection against tidal flooding from the River Clyde and fluvial flooding from Mill Burn. The pumping station's maximum flow rate has been specified to cover a 1 in 200 year flood event. KSB Amacan pumps were chosen for this station as their characteristics ideally suit the transfer of very high flows of water at low heads; their slim design makes the submersible pump ideal for installation into narrow discharge canisters, yet they are extremely powerful, ensuring flood-prone areas are reliably drained. Ferrier Pumps Ltd carried out the mechanical installation at the Renfrew project site and found the pumps were easy to install as the Amacan pump's own weight ensures self-centering seating of the O-ring seals in the discharge canisters, a simple but effective design feature. The Amacan pumps come with speed submersible pumps from their axial flow Amacan pump range and one variable speed sump pump of type Amarex KRT, to the North Renfrew Flood Prevention Scheme near Glasgow. KSB also supplied the 800mm diameter pump discharge canisters which are currently installed in the Storm Pumping Station situated on the south bank of the River Clyde. BY ABBigAYle Morris AND TiM PeArsoN, KsB Work underway to install the four-pump station in Renfrewshire • Drivers ● Pumping station required to protect against tidal flooding from the River Clyde and fluvial flooding from Mill Burn. ● Powerful yet slimline pumps needed to transfer very high flows of water at low heads within narrow discharge canisters. ● Maximum design flow for the station is 5500l/s, based on four pumps working simultaneously.
