Water resources management plan

Final plan published   

Every five years we review and update our water resources management plan which sets out how we will maintain a balance between the demand for water and available supplies while ensuring the environment is protected over the next 25 years.

In May 2013 we published a draft plan for public consultation which was open for comment until the end of July 2013. In reply to the comments that were made on our plan we prepared a Statement of Response Report in November 2013. We also incorporated changes we were making to the plan as a result of the consultation in a revised draft version of the Water Resources Management Plan.

The Environment Agency then reviewed our statement of response and revised draft plan and made recommendations to Defra and the Secretary of State regarding whether our plan can be published as a final version or whether further information or and inquiry in necessary.

In May 2014 we were informed by Defra that we could publish our plan as a final version without the need for further information or an inquiry.

Our final water resources management plan technical report and data tables are available to download by clicking on the links on the right of this page.

Overview of the plan

The key objectives of our plan are to:

  • Reduce the demand for water.
  • Reduce leakage.
  • Reduce abstraction where it is required to improve river flows.
  • Identify whether there is scope to transfer water to neighbouring companies.

We undertook a detailed review of our demand projections to take account of population growth, housing developments, changing patterns of household water use and changing demands from our commercial customers.

We also reviewed potential changes to the yields available from our water sources, including assessing the potential impacts of climate change. Our analysis took account of the work we currently have underway to more fully integrate our water supply grid and make 25 Ml/d of licence reductions to improve river flows.

Our calculations forecasted that we will have a surplus of supplies over demands for the next 25 years.

We plan to continue to reduce demand and leakage by accelerating metering in our region through installing meters on households when customers move house and also by providing enhanced water efficiency services to help customers reduce their water use further. These investments will be dependent on Ofwat approving our Business Plan in December 2014. 

September 2012 update 

In September 2012 we published an interim view of our supply demand balance forecasts that were available at that time. We did this to make neighbouring companies and regulators aware of potential water surpluses that could be available for future new transfers.  

Our interim assessment identified future surpluses that could be available as bulk supply exports as follows:

  • Company single resource zone: approximately 10 Ml/d.
  • North Wiltshire area: approximately 5 Ml/d.
  • Exmoor / Taunton / Bridgwater area: approximately 10 Ml/d.

We did not identify any areas of supply demand deficit.

The analysis assumes that our current scheme to more fully integrate our supply grid will be in place and that reductions in abstraction will be made from some of our sources in the Hampshire Avon catchment, as agreed with the Environment Agency. These changes will be in place in 2018.

We notified neighbouring companies of these potential export options and invited other water undertakers to contact us should they wish to discuss the development of a bulk supply option.

Our last plan

The final plan we published in 2010 is currently being implemented and involves:

  • Reducing abstraction by 23.5 Ml/d from environmentally sensitive sources to improve river flow.
  • Developing a more integrated water supply grid to connect up areas in surplus with areas in deficit.
  • Encouraging and enabling our customers to use water wisely.
  • Protecting our groundwater resources from pollution such as nitrates through the continuation of our successful catchment management programme.
