Abingdon Reservoir

Affinity Water draft Water Resources Management Plan (WRMP)

Affinity Water, who are the partners with Thames Water in the proposed Abingdon Reservoir, are preparing their revised draft Water Resouce Management Plan.

As Affinity's supposed needs are the driver for the early construction of the Abingdon reservoir (2025-2037), we believe it is very important for Oxfordshire Stakeholders to reply to this consultation.

GARD's analysis of the Affinity Plan found that Affinity Water has not proven the need for the Abingdon Reservoir at any date before the late 2060s, and there is no case for its construction starting early. There are other, more flexible, and more quickly delivered solutions to the possible supply shortages in Affinity’s central zone from the mid-century onwards, if indeed these arise at all. There are simpler, less costly and faster ways of achieving more chalk stream relief than Affinity’s plan, without waiting for Abingdon reservoir, which may never be needed at all for supplying Affinity’s customers.

The consultation closed on 26 April 2019. Our submission can be seen here and we await their response.

Thames Water draft Water Resources Management Plan (dWRMP19)

Thames Water consulted on their plans for increasing water supply earlier in 2018 and we responded to the consultation. See our response. During the consultation they changes key areas of the plan including the scale of population growth during the plan period, changes to their plans to cut leakage (to meet the Ofwat targets), and the addition of several other water resources not included in the earlier draft. We (any many others including the County and District Councils) believe that these changes mean that there should be a second consultation and wrote to the Secretary of State to say so. See our letter.

On 10th August 2018, Thames Water issued a press statement conceding the case for a second public consultation on their revised draft Water Resources Management Plan 2019-2024 (known as rdWRMP19)and we responded to the consultation. See our response.

They have now published their Statement of Response No 2 which presents their response to the further consultation and updates to parts of their revised draft plan. If you would like to read these documents please go to their website thameswater.co.uk/wrmp.

The Department for Environment, Food and Rural Affairs will review the revised draft plan, and updated documents, and in consultation with the Environment Agency and other regulators will decide whether to approve the plan, request further changes, or recommend further scrutiny either through a public hearing or a public inquiry.

For more background


Thames Water is preparing its long term plan and this includes the reservoir between Marcham, Hanney, Drayton and Steventon. After two consultations the plan has not changed and still includes a proposal for an above-ground reservoir which will be contained by walls between 15 and 25 metres high with building starting in 2025. It would hold about 150 million cubic metres of water and be capable of providing 600 million litres per day.

Group Against Reservoir Development

Action organisation GARD (Group Against Reservoir Development) has battled for years against Thames Water's proposals for an "Abingdon reservoir".
They believe that other options are less costly, less damaging to the environment, less disruptive to local communities and more robust against climate change than the reservoir.

We submitted our objections to the plans pointing out that the reservoir was unnecessary and the document can be accessed here ( our submission)
