We have provided constructive challenge to Severn Trent in the development of the 2020 to 2025 business plan.

We act in customers' best interests by challenging Severn Trent to consult their customers about important topics, from affordability to the environment, and gain their honest views. We then ensure their opinions and key customer issues are fully understood and reflected in Severn Trent's business plan.

Our role

listen and respond

An introduction to the Water Forum

Customers said... Severn Trent acted

In previous years, the Water Forum has encouraged dialogue between customers and Severn Trent, resulting in real progress.

Here are a few examples of what we helped Severn Trent achieve as they planned for 2015-20.

Experts with different perspectives

The Water Forum has an independent Chair. There are 11 other Forum members who have either a statutory remit, a key interest in the water industry, or provide specialist knowledge to support and challenge the delivery of Severn Trent's current plan, and the development of its next business plan (2020-25).

The Water Forum's terms of reference set out the group's purpose and vision. You can download the Water Forum's terms of reference in PDF format.

Water Resources Management Plan

Explaining our Water Resources Management Plan.


A statutory requirement


It is a statutory requirement that every five years water companies produce and publish a Water Resources Management Plan (WRMP).

The WRMP should demonstrate that we have long-term plans in place to accommodate the impacts of population growth, drought, our environmental obligations and climate change uncertainty in order to balance supply and demand.

It consists of several elements.

How the plan is made

On our journey to the final plan we follow the statutory timetable set out by Defra and the Environment Agency, we hold regular consultations with our
customers and stakeholders to identify potential solutions, and we consider the environmental impacts alongside affordability.


Future challenges

Our Water Resources Management Plan must demonstrate

  • Resilience to a range of risks – e.g. drought, loss of supplies.
  • Flexibility and adaptability – the plan must be robust to changes to supply and demand forecasts in the future.
  • Approach to climate change – drier summers and wetter winters make it harder to meet peak demand.
  • Sustainable abstraction options – which don’t deplete our natural resources or have a negative effect on biodiversity and our local river environment.
  • Planned proactive work – proactive maintenance of our network to reduce amount of water wasted by leakage and optimise the use of our sources.


Water Resource Management Plan 2019

We published our final Water Resources Management Plan in August 2019.

In February 2018 we published our draft WRMP for stakeholder consultation and we were pleased to receive comments from 22 different stakeholders. 

We reviewed each of these comments and, where appropriate, we used the feedback to update and improve our plan.

In September 2018 we published a summary of the stakeholder feedback and we described the resulting changes to our plan.

We also confirmed that the changes we made did not materially alter the recommendations made in our draft WRMP, as laid out in our Statement of Response.

In July 2019 we received approval from the Secretary of State that we should publish our final Water Resources Management Plan.


Market information

We provide Water Resources Market information to enable third parties to identify where we may need additional water resources and to test how their proposals compare to our own supply options.

This map shows where our fifteen water resource zones (WRZ) are located.


You can download a spreadsheet containing key market information and data on our water resources position for each zone, and a Shapefile that can be used in Geographic Information Systems to depict our water resource zone boundaries.

Bid assessment framework


The purpose of this Bid Assessment Framework is to support the market for water resources, demand management and leakage services.

It provides guidance and a template to enable you to submit proposals to help us maintain our water supply balance.

This process is designed to ensure transparency and fairness throughout the tendering process and builds on existing processes and our obligations for water resource planning, procurement law and competition obligations.


The BAF was introduced to encourage competitive bidding market for water resources, demand management and leakage so that we will adopt the best value options regardless of their origin.

This way we will ensure our customers have the lowest possible bills.

We’re happy to receive proposals from all organisations.

All these proposals will be subject to a straightforward and transparent pre-qualification evaluation. 

We run an annual cycle to generate bids but we are more than happy to accept ad-hoc or speculative submissions at any time.

We will ensure confidentiality in two ways.

  1. We are happy to enter into a non-disclosure agreement.
  2. We have a separate team that will assess your proposal. Those developing water resource schemes, demand management and leakage services will not have access to your ideas or intellectual property.

Get in touch with us if you have any questions or feedback


If you have queries on any part of the process, or want to discuss technical aspects of your proposal, please get in touch by emailing our team at BAFProcurement@severntrent.co.uk


Drought plan

Droughts are naturally occurring events that occur when there is below average rainfall for prolonged periods of time. We need plans to manage our system when  droughts happen.


Maintaining our service

The Water Act (2003) made it a statutory requirement for water companies to produce and maintain a Drought Plan every five years. Our Drought Plan sets out how we will manage our resources and supply system during dry and drought years, whilst balancing the interests of customers, the environment and the wider economy. The Drought Plan Directions 2020 required water undertakers to submit a draft drought plan to Defra by the 1st of April 2021. 

We submitted our new Draft Drought Plan on 30th March 2021, and in accordance with the Drought Plan Regulations 2005 we have formally consulted on this draft plan. The consultation period closed on 27 July 2021, and we have now published our Statement of Response and revised plan which can be found below. We expect to publish our final Drought Plan in early spring 2022. 

On the grounds of national security, in the draft Drought Plan we have omitted the names and locations of certain critical national infrastructure.  


Defra gave us permission to publicly consult on this draft plan on 10 May 2021.


We have published a non-technical summary of our draft drought plan.

We also undertook a Strategic Environmental Assessment (SEA), a Water Framework Directive assessment and a Habitats Regulation Assessment (HRA) of our draft 2022 to 2027 Drought Plan to take environmental impacts into account.

We consulted on our draft SEA between 1st February 2021 and 8th March 2021. 

To submit feedback on our draft SEA or to request copies of our current Water Framework Directive and Habitats Regulation Assessment reports, contact the team by emailing futureconsultation@severntrent.co.uk

For reference, our 2014 to 2019 drought plan can be found below.


Green Recovery

We want to share with you our Green Recovery initiatives which sets out our plans to enhance our regions environment and better serve our customers and communities. 

Life beyond the pandemic

In July 2020, the government along with our regulators penned a letter to water companies inviting the water sector to play their part in the country’s Green Recovery from the Covid-19 pandemic. As a socially purposeful company, we were keen to get involved and recognised the role we can play in helping to meet the economic and social challenges that our country faces – so we started talking to our customers and got working on plans right away. 

£565m investment
2,500 jobs
2 UK first projects

In July this year, Ofwat published their final determination which included £566m for Severn Trent, enabling us to deliver long-term, sustainable benefits for current and future generations in our region. This includes improving the environment, creating over 2,500 jobs, enhancing our regions skills and ultimately, saving our customers money in the long term. The Green Recovery will enable Severn Trent to lead the way in a number of projects, many of which will be a first for the UK. 

Our Projects will tackle long-term issues that we know are important to our customers. The Green Recovery projects will:

  • Increase water supplies with enough water to supply a city the size of Derby, using low carbon technology; 
  • Encourage wild swimming by trialling the creation of two bathing rivers in stretches of the River Leam and the River Teme;
  • Accelerate environmental commitments by improving 500 kilometres of river five years earlier than planned; allowing communities and wildlife to benefit sooner; 
  • Create a scale trial using a nature-based approach to reduce the risk of flooding whilst creating a green environment which will significantly benefit the town of Mansfield; 
  • Help customers to save water by introducing over 150,000 smart meters; and
  • Remove old customer-owned lead pipes in up to 26,000 homes in two trial areas and using innovative techniques to find and replace them.

Water Resources

Climate change and population growth is putting increasing pressure on the UK’s water resources. In less than 25 years a lack of water could limit growth, jobs and impact people’s everyday lives.  

Water companies are developing plans to meet this challenge, such as reducing demand and tackling leakage, as well as developing new sources of water.  At the same time, we need to make sure we protect the nature and wildlife that rely on the water systems which are the source of all our supplies.
Every 5 years we produce a Water Resources Management Plan, which you can see here.  That sets out how we’re going to supply our customers with the 2.4billion litres of water needed every day.

But no one water company can solve this on their own – we need to work together to make sure there is enough water in the future for all our customers, businesses and to protect the natural environment. 

As well as this, we’re working with various other water companies on a range of options – called Strategic Resource Options (SROs).  These options are in the very early stages and right now we’re concentrating on what’s possible and how we could deliver projects to help make sure everyone has enough water in the future.


To support the progression of strategic options, the Regulatory Alliance for Progressing Infrastructure Development (RAPID) has been established by Ofwat to help accelerate the development of new water infrastructure. It seeks to improve regulation and remove barriers to help the water sector respond to long-term water resources challenges. RAPID is comprised of representatives from Ofwat, the Environment Agency and the Drinking Water Inspectorate.  These are all our key regulators who make sure we do the right thing for our customers and the environment.

Development funding is available to us and the other water companies who are progressing strategic solutions through RAPID.



Severn Trent is working on the following options.

  • Severn to Thames Transfer
    We are working with United Utilities and Thames Water looking at the possibility of moving water from a number of sources in Wales, the North West and the Midlands to the South East of England by releasing water into the River Severn and then transferring it on to the River Thames.
  • The Grand Union Canal
    We’re working with Affinity Water and the Canal & River Trust looking at an option that uses the existing canal infrastructure to transfer treated wastewater from Minworth in the Midlands to Affinity Water in Hertfordshire and North West London.
  • Minworth
    A source of raw water to support either the Severn to Thames Transfer SRO, the Grand Union Canal SRO, or a combination of the two. We’re partnered in this SRO by Affinity Water
  • Severn Trent Sources
    Options for new or increased sources of raw water.  This SRO will also support the Severn to Thames Transfer SRO
  • Upper Derwent Valley Reservoir Expansion
    Working with Yoirkshire Water, we're looking at ways of expanding the reservoir capacity

Gate 1 reports, decisions and queries

The first stage of the RAPID process for agreeing the SROs is called ‘Gate One’.  At this stage, we must demonstrate each strategic solution’s progress and viability. This involves setting out plans for delivering the proposed solution, including early conceptual outline designs alongside strategies for engaging stakeholders, gaining planning permission and for procuring and operating the new infrastructure.

It's important to note that all our strategic solutions are in their early stages, with key details such as site selection and early concept designs still being progressed. 

On this page you will find the Gate 1 reports that were submitted to RAPID in July and December 2021, the decisions made by RAPID and the queries that we answered on each plan as part of the process.

Next Steps

RAPID has published its draft decisions on the first four of the SROs on the Ofwat website here.

All of the Severn Trent sponsored schemes that were submitted in July 2021 have been recommended for continuation to Gate 2.  This means that work will now continue to develop each of the options in more detail.  The UDVRE scheme has not yet been assessed.

Work throughout 2020-2025 will look at appropriate regulatory, technical and environmental aspects of each of the options. If the results of these investigations are favourable it will allow them to be considered as an option in future regional and water company Water Resource Management Plans. If the scheme progresses, it could bring many benefits to the region, including investment in water infrastructure, improvements for nature and creating skilled jobs. 

The next milestone will be Gate 2 reports being submitted to RAPID in October 2022. Before then, we will be working to develop more detail on each option. Once more detail is available, we will share information on our emerging proposals including identified locations of solutions and routes of transfers with local communities, inviting feedback through a period of consultation.
