Notice Title

Supply of Mechanical & Electrical (M&E) Equipment for the Water Management Zones (WMZ) at Sizewell C site

Notice Description

This expression of interest (EOI) serves to inform the supply chain about the upcoming procurement for the supply of Mechanical & Electrical (M&E) Equipment for the Water Management Zones (WMZ) at Sizewell C site. This equipment supply will be desilting type units to control the suspended solid discharge from the outfalls. These units shall be supplied with the pumps and ancillary equipment necessary to lift the water from the discharge network to the treatment plant and for integrating the pump with the control system. These treatment plants will be primarily used to treat surface runoff water collected via the site drainage network, but also includes emergency potable water discharges and some groundwater dewatering that cannot be practically treated at the main groundwater treatment plant. This table shows the space requirements, power requirements and source and flow rates for each WMZ treatment plant: WMZ / Treatment plant footprint / Treatment flow rate (l/s (m3/hr)) / Power requirement (kW) / Power source WMZ 1 12x6m 23.7 (85.3) 15-20 Generator WMZ 2 12x6m 27.6 (99.4) 15-20 Network WMZ 3 16x6m 40.7 (147) 35-40 Network WMZ 5 12x6m 31.2 (112) 20-25 Generator WMZ 7 25x7.5m 62.0 (223) 35-40 Generator TMO 25x25m 200 (720) TBC Generator The treatment plant is only required to manage total suspended solids (TSS); hydrocarbons are assumed to be trapped in the WMZ and will be removed using booms deployed by client. The concentrations for TSS are as follows: * Outfall to the SSSI 60mg/l * Outfall to the sea 250mg/l pH correction is not included at each WMZ but provision of it might be required on some plants.
