Regional water resources

Water companies are required to work together to produce regional water resource plans and where possible assess the potential to move water from areas of surplus to areas of deficit.

Working with other water companies

Wessex Water is proud to be part of the West Country Water Resources group, along with Bristol Water, South West Water, the Environment Agency and Natural England.

We are working together to produce our first Regional Water Resources Plan. We consulted on a draft emerging plan in February 2022. The next version will be available for consultation in early 2023.

In addition to producing a regional plan, regulators have asked us to investigate the feasibility of potential regional schemes over the next five-year period. There are three schemes in our region, which are all following a gated process overseen by RAPID.

Current schemes

The Cheddar two reservoir and transfer scheme, which was formerly known as West Country North Sources and Transfers, considers the potential to develop a new reservoir in Bristol Water’s area and transfer the water to Wessex Water’s area.


The Poole water recycling and transfer scheme, which was formerly part of West Country South Sources and Transfers, is investigating the potential to recycle water from Poole water recycling centre for use as a water resource.


The Mendip Quarries scheme considers the potential to repurpose a quarry in the Mendips into a reservoir to provide additional water supply. We have produced a summary report on the initial feasibility of this option.


Previous investigations

The superseded schemes Gate 1 South Sources and Transfers investigation, and the Gate 1 Southern Transfer investigation considered transfers from South West water’s Roadford reservoir and water recycling to support Southern Water. The Gate 1 Mendip Quarries SRO report has been superseded with the latest Gate 2 document above.

We have responded to queries from RAPID on these schemes, which include specific comments and answers, in addition to the provision of our Environmental Assessments.
