Abingdon Reservoir

Ofwat Decision

All Water Companies have now submitted their plans to Ofwat and The Environment Agency and some have been approved. They are not yet convinced by the Water Companies' (including Thames Water and Affinity) plans for new water sources in the South-east.

The 'final view' of the Water Regulator (Ofwat) on the Water Companies' plans for 2019-2024 has been published (16th December). The section of the decisions relating to future water resources can be found at Ofwat Strategic Study. Ofwat and The Environment Agency require a major strategic study to inform fresh plans for water resources across the South-East. This could take up to 3 years.

GARD's submission to Ofwat has been loaded onto their website and  can be seen at GARD submission to Ofwat

Affinity Water draft Water Resources Management Plan (WRMP)

Affinity Water, who are the partners with Thames Water in the proposed Abingdon Reservoir, have prepared their Water Resouce Management Plan.

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.

Our submission can be seen here.

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 revised plan. If you would like to read these documents please go to their website thameswater.co.uk/wrmp.

For more background


Ofwat has reviewed the water companies long term plans and has requested further studies on five new strategic water supply options. These studies will be overseen by an organisation called RAPID – a consortium of water industry regulators – and the work will be managed through a new “gated” regulatory process. The process is designed to make sure all new strategic water supply options are considered in a fair and consistent way.
The five options for our area are:
• A transfer of water from Wales, the Midlands and North West, via the River Severn to the River Thames
• Water reuse schemes in London
• A transfer from Thames Water to Affinity Water
• A transfer from Thames Water to Southern Water
• A new reservoir in between Marcham, Hanney, Drayton and Steventon.

The proposed new reservoir is 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)
