Water Resources Plans


We publish our Water Resource Management Plan (WRMP) every five years to show how we plan to supply enough water to meet demand over the next 25 years. We must ensure that we balance the demand for water in our supply area against the available water resources whilst minimising the impact on the local environment. This is a statutory process introduced by the Water Act 2003 and there are a number of stages during which we consult our stakeholders and invite comment.

Find out how we are reviewing all the potential opportunities available to us to either reduce demand for water; or increase the amount of water we are able to put into supply - click here.



Final Water Resources Management Plan (fWRMP)

On 14th May 2014, DEFRA wrote to us and advised that the Secretary of State had approved our WRMP and that we should publish it. Our final WRMP covers the period 2015 to 2040.

Draft Water Resources Management Plan (dWRMP)

We submitted our draft WRMP in March 2013, and released it for public consultation in May 2013.

Statement of Response

We consulted on our draft WRMP between May and August 2013. We received a number of responses from local residents, local interest groups, local councils as well as our key stakeholders: the Environment Agency, Ofwat, Natural England, English Heritage and the Consumer Council for Water.

We have revised our WRMP as a result of our consultee feedback and have prepared our Statement of Response to explain how our Plan has changed. We submitted our Statement of Response to DEFRA, the Environment Agency and Ofwat on 15th November 2013.

Our Statement of Response, revised WRMP, technical reports and tables are key components of our Business Plan, that we will submit to Ofwat on 2nd December 2013. Whilst the publication of our revised WRMP is not a requirement of legislation, we have chosen to publish it on our website. Please note that our revised WRMP is not a consultation document.

Technical Reports

We have also updated our technical reports in support of our revised WRMP but, for security reasons, we are not able to make the reports publically available on our website.

Additional Information

DEFRA asked us to provide some additional information in support of our revised WRMP and Statement of Response on 5th March 2014. We responded on 21st March 2014 and provided further details, fully answering DEFRA’s queries. The letter from DEFRA and our response is available to view.

In 2010, we published three Water Resources Management Plans, one for each of our three regions, for the period 2010 – 2035. Please click on the region below, to download a copy.

Annual Review

We are required to review our WRMP every year and, together with data tables, must send our annual review to the Environment Agency. Please click on the link below to view a copy of our annual review for 2015 of our three WRMPs published in 2009 and 2010 for the 2009 Price Review.

Strategic Environmental Assessment (SEA)

We anticipate a deficit in our baseline supply demand balance due to population and housing growth, sustainability reductions and climate change. This will require the implementation of options to close the gap and as a result, we are required to undertake a Strategic Environmental Assessment under both the European Directive (2001/42/EC) and the Environmental Assessment of Plans and Programmes Regulations (SI 1633 2004).

The SEA Scoping Report is the first part of this process and outlines information on the plan area, the potential options being considered to meet the anticipated supply demand deficit and how the environmental assessment will influence the appraisal of schemes during the assessment process. Within the report we ask questions about our plan, processes and approach and we invite your comments so that these may be taken into account in preparing the plan.

Drought Management Plan (DMP)

Our Drought Management Plans describe how we will monitor and manage future drought related events. The plans show how we will restrain demand and mobilise extra resources when they are needed whilst minimising the need for Drought Orders and Drought Permits, the mechanisms that allow us to restrict use of water or change our abstraction plan for our water resources. Our plans must show how we will achieve all this while ensuring the supply to customers remains secure.

Water companies are required to review their Drought Management Plans every year to account for recent operational events. Since the original publication, the three regions we operate in have undergone unification and through this annual update we have merged the three regional plans into one company plan, covering all eight Water Resource Zones.

Need and availability of water

This document sets out our initial baseline estimates of the supply demand balance for the next WRMP. This shows where we have a surplus or deficit of resources and we invite proposals to either utilise that surplus or contribute to supply and help reduce the deficit.
