What is being bought

As part of wider plans from the West Country Water and Environment Group (WCWE), two projects are in early planning and development, namely Cheddar 2 Reservoir, and the Poole Water Recycling and Transfer Project. This Preliminary Market Engagement Notice refers only to the Cheddar 2 Reservoir, led by South West Water, however a separate Preliminary Market Engagement Notice is also concurrently being issued by Wessex Water for the Poole Water Recycling and Transfer Project. A Planned Procurement Notice reference 2025/S000-037919 has previously been published in relation to this Project in July 2025. It is South West Water's intent to procure a Competitively Appointed Provider (CAP) to design, build, finance, and where appropriate, operate and maintain a new reservoir (Cheddar 2 Reservoir), water treatment and transfer scheme under the Direct Procurement for Customers (DPC) model. At this stage, it is intended that the Project scope comprises a new earth embankment reservoir with a useable capacity of 8,200Ml, adjacent to the existing Cheddar Reservoir. The Project also comprises associated ancillary works, including a raw water transfer to a new Water Treatment Works, and approximately 75km of potable water transfer pipeline from South West Water's Bristol area to its customers in Devon. The estimated capital value of the work is approximately £750 million (excluding VAT), and the estimated total expenditure (inclusive of operating and maintenance costs) is c. £1 billion (excluding VAT). Further details regarding the Project are available within the Market Engagement Pack, and details of how to access this are provided below. The Cheddar 2 Reservoir Project is proposed to be delivered via a Direct Procurement for Customers (DPC) model. Under the DPC model, it is intended that a Competitively Appointed Provider (CAP) will be responsible for taking forward the design, build, financing, commissioning, operation and maintenance of the majority of assets within the Cheddar 2 Reservoir Project. Further to the recent launch event held on Tuesday 9th September 2025, South West Water invites interested parties via this Notice to participate in an initial round of Market Engagement, as part of a planned ongoing programme of market engagement for the Cheddar 2 Reservoir Project. The programme of engagement is proposed to help develop a wider understanding of the delivery of the Project from both a construction and investment perspective, and presents an opportunity for South West Water to engage and collaborate with the market in refining its delivery and commercial model, procurement approach and contracting terms. Additionally, the programme of market engagement seeks to encourage multi-party discussions that will align the Project's development and presentation to market with market trends, taking into account the perspectives of both Investors and Main Works Contractors who it is envisaged would form and comprise the CAP. We envisage that this round of Market Engagement will comprise registration of interest and completion of a short Questionnaire, followed by a series of bilateral discussions with a range of interested parties who are representative of the target market.

Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 45. The category anchor is Demolition, site preparation and clearance work (45111000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.

Comparison setProceduresReported bids per procedureNamed award suppliersPrice evidence

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.

Price-outcome signal

Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.

    "description": "As part of wider plans from the West Country Water and Environment Group (WCWE), two projects are in early planning and development, namely Cheddar 2 Reservoir, and the Poole Water Recycling and Transfer Project. This Preliminary Market Engagement Notice refers only to the Cheddar 2 Reservoir, led by South West Water, however a separate Preliminary Market Engagement Notice is also concurrently being issued by Wessex Water for the Poole Water Recycling and Transfer Project. \nA Planned Procurement Notice reference 2025/S000-037919  has previously been published in relation to this Project in July 2025. \nIt is South West Water's intent to procure a Competitively Appointed Provider (CAP) to design, build, finance, and where appropriate, operate and maintain a new reservoir (Cheddar 2 Reservoir), water treatment and transfer scheme under the Direct Procurement for Customers (DPC) model. \nAt this stage, it is intended that the Project scope comprises a new earth embankment reservoir with a useable capacity of 8,200Ml, adjacent to the existing Cheddar Reservoir. The Project also comprises associated ancillary works, including a raw water transfer to a new Water Treatment Works, and approximately 75km of potable water transfer pipeline from South West Water's Bristol area to its customers in Devon. The estimated capital value of the work is approximately £750 million (excluding VAT), and the estimated total expenditure (inclusive of operating and maintenance costs) is c. £1 billion (excluding VAT). \nFurther details regarding the Project are available within the Market Engagement Pack, and details of how to access this are provided below. \nThe Cheddar 2 Reservoir Project is proposed to be delivered via a Direct Procurement for Customers (DPC) model. \nUnder the DPC model, it is intended that a Competitively Appointed Provider (CAP) will be responsible for taking forward the design, build, financing, commissioning, operation and maintenance of the majority of assets within the Cheddar 2 Reservoir Project. \nFurther to the recent launch event held on Tuesday 9th September 2025, South West Water invites interested parties via this Notice to participate in an initial round of Market Engagement, as part of a planned ongoing programme of market engagement for the Cheddar 2 Reservoir Project.  \nThe programme of engagement is proposed to help develop a wider understanding of the delivery of the Project from both a construction and investment perspective, and presents an opportunity for South West Water to engage and collaborate with the market in refining its delivery and commercial model, procurement approach and contracting terms.  \nAdditionally, the programme of market engagement seeks to encourage multi-party discussions that will align the Project's development and presentation to market with market trends, taking into account the perspectives of both Investors and Main Works Contractors who it is envisaged would form and comprise the CAP. \nWe envisage that this round of Market Engagement will comprise registration of interest and completion of a short Questionnaire, followed by a series of bilateral discussions with a range of interested parties who are representative of the target market.",
