Description

Anglian Water Services (AWS) WRMP24 has identified significant challenges for the East of England, primarily due to a forecasted reduction in available supply of potable water and an increase in the demand forecast. Without intervention, a daily shortfall of 593 megalitres (Ml) of water is estimated by 2050, which equates to approximately half of the current volume of water entering the network. As a result, two desalination plants have been identified as part of the Adaptive Plan to address the shortfall in Norfolk and Lincolnshire. Both desalination plants will abstract and desalinate seawater from the North Sea. Initial design assumptions are that the desalination plant will include pre-treatment, reverse osmosis, and remineralisation, before the treated water is blended and pumped into supply and the brine waste is discharged via a long outfall to sea. Desalination is a new technology for Anglian Water, therefore we do not have sufficient experience within the business and expertise is limited within our usual supply chain. This was a tender exercise to procure up to two Desalination Technical Partners to support us in the development stages for both sites. We awarded to two partners - a Primary Partner and a Secondary Partner. The Primary Partner will be awarded the minimum scope of work for both sites and any additional work over and above this is to be awarded at Anglian Waters discretion. As a result even though the tender notice value is £29m (ex VAT), the Primary Partner is only guaranteed the minimum scope spend, estimated to be £4.7m. The Secondary partner will play a vital role in strengthening the overall framework by providing resilience and continuity. The Primary and Secondary Partners are both joint ventures, as per the below ; Primary - Tyspa Limited & Stantec UK Limited (Bid submitted by Typsa, through Anglian Waters online portal, on behalf of the joint venture) Secondary - RSK Environment Limited & Gutteridge, Haskins & Davey Limited (Bid submitted by Binnies, through Anglian Waters online portal, on behalf of the joint venture. Binnies is a subsidiary of RSK Environment Limited) Please note, due to the formatting of this notice the two successful joint ventures are showing as 4 suppliers. This is because we have the two contracting entities listed per venture.
