In August 2018, decommissioning and demolition works began on the old Slough Heat and Power Plant to clear the area for a new 50MW energy-from waste recycling facility. This has become known as Slough Multifuel and has cost around £350 million to construct. Not all of the old Slough Heat and Power Plant was decommissioned with some of it remaining open to supply energy, water and heat. The new development is a 50:50 joint venture between SSE Thermal and Copenhagen Infrastructure Partners. The facility will work in a similar way to typical energy-from-waste facilities, however it will burn pre-processed waste derived fuel to produce electricity and heat.
A large number of pollution control, containment and pumping is often required on new energy-from-waste facilities. On this project SPEL designed and manufactured 2no. SPEL ‘V-Series’ vertical packaged pumping stations, a SPEL Tankstor 200 Series (1.2m diameter) with 7,000 litre capacity as a fuel spillage tank and 2no. SPEL Tankstor 600 Series (4m diameter) tanks with 250,000 litres capacity each for firewater containment.
The first package pumping station SPEL manufactured was from our 300 Series size range (1.8m diameter) with a total depth once installed of 2.5 metres. The industry leading WRc Approved Wet Well Chamber was chosen to ensure the highest quality and complete peace of mind for the client that the tank and pumping station design, manufacturing and installation processes have been approved by WRc. The pumping station was supplied to site with all guiderail systems and pump pedestals, inlet and discharge connections and valves fitted within the tank for a quick and simple, once piece installation. This pumping station was pumping firewater at around 34 l/s with a 5.2m head with a duty/assist pumping arrangement over a 32m long rising main. The pumps chosen for this application were manufactured by Grundfos.
The second package pumping station was a 400 Series (2.6m diameter) that will be installed at a total depth of 3.5 metres to cater for the incoming and outgoing connection heights. A 12” discharge was required and this was supplied fitted within the pumping station in stainless steel as requested by our customer. This particular pumping station was supplied with Xylem Flygt pumps that were pumping at around 150 litres/second at a 2.8m head over a 70m long rising main. The pumping arrangement was duty/assist with both pumps working together if required to meet the flow rate of 150 litres/second.
