 Thames Water has adopted a new “integrated” approach to sourcing its pumping system requirements including pump supply, repairs and maintenance, which have a combined annual spend in excess of £13 million.

The following ten linked Framework Agreements have been awarded to the nine suppliers – with each Agreement  comprising 3 lots covering all the TW geographic regions.

1. Application Raw Water – Surface (Axial flow or mixed flow pumps to lift from river to reservoir or reservoir to treatment work; usually low head, high flow)
2. Application Raw Water – Ground (Normally borehole pumps, submersible or line shaft based on whole life cost)
3. Application Clean Water - Low Lift (Axial or mixed flow as inter-stage pumps in the water treatment process)
4. Application Clean Water - High Lift (High head, high flow centrifugal to lift from works to service reservoirs or from service reservoirs to distribution/tower blocks. Also from Ring Main to distribution)
5. Application Sewage Network - 0 to 7,5 kW, Pump Supply including Modular Pumping Stations (Usually small submersible wet well sewage. Prebuilt pumping stations to WIS 4-04-01/02)
6. Application Sewage Network - > 7,5 kW, Pump Supply including Modular Pumping Stations (Wet well or dry well sewage handling pumps (This framework agreement will include submersible type pumps to a maximum of 100 kW. For submersible pumps above this threshold, then Thames Water reserves the right to source outside of the framework agreement). Prebuilt pumping stations to WIS 4-04-01/02)
7. Application Sewage Network - Strategic Pumping Stations (End suction dry well pumps with large throughlet with rag handling capabilities)
8. Application Sewage Process - Dry Solids content below 6 % (Wet well or dry well sewage handling pumps (this framework agreement will include submersible type pumps to a maximum of 100kW. For submersible pumps above this threshold, then Thames Water reserves the right to source outside of the framework agreement)
9. Application Sewage Process - Dry Solids content above 6 % (Positive displacement pumps)
10. Application Flip Pumps (Package wastewater pumping stations to WIS 4-04-01 or similar)

The lots for each Agreement consist of :

Lot 1 Supply of Pumps: The scope will cover to design, solution selection (based on lowest whole life cost), manufacture, at-works test, provision of drawings, tagging (nameplates), supply, packing, delivery, offloading, on-site testing, installation, commissioning, provision of associated documentation and necessary certification and warranties and operator / maintenance training of selected applications. Estimated spend on the supply of pump is approx. £7 million a year.

Lot 2 Supply of Spares: The scope will cover the provision of spare parts of selected pumps including the inventory management and stock holding of strategic spare parts. Estimated spend on the supply of spare parts is approx. £3.5 million a year.

Lot 3 Repair and Maintenance Services: The scope will cover planned and reactive maintenance of TWUL pumping systems, including root-cause failure investigation, repair, overhaul and servicing services to cover a wide range of pumps, motors and gearboxes of varying sizes and makes used in the water and sewage industry. Work will cover both on- and off-site work. Estimated annual spend on external labour for pump repair and maintenance services is approx. £2.5 million a year.

The agreements will run for an initial duration of 3 years with options to extend biannually up to a maximum length of 7 years,  subject to satisfactory reviews on price and supplier performance.

Suppliers to conduct pilot trials

During the duration of the agreement (up to 12 months each) the successful suppliers will be invited to conduct pilot trials to test the feasibility of operational and commercial models, to improve pump performance and availability and to support the collation of asset data.

During the trials, the suppliers will also be assessed on their performance and if the supplier does not perform satisfactorily then Thames Water will stop the trial early and may not involve the supplier in future trials. Following completion of the trials Thames Water will review the results and may adjust its pump strategy, either within the scope of the Framework or via a separate sourcing exercise.
