The Water Forum is an independent, expert panel that challenges

Severn Trent to listen and respond better to customers.

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 Drought Plan Directions 2020 now require water undertakers to submit a draft drought plan to Defra by the 1st of April 2021. We submitted a revised Drought Plan in 2019 (2019-2024) following on from the hot/dry weather event to include our learnings. As directed by Defra, we will not be continuing this process.

We will be submitting a new Draft Drought Plan next year, and in accordance with the Drought Plan Regulations 2005 we will be pre-consulting stakeholders for this plan. 

If you have any comments you would like to communicate to us for the Draft Drought Plan 2021, please forward them by email to futureconsultation@severntrent.co.uk by the 14th of August for consideration.

The Water Act (2003) made it a statutory requirement for water companies to produce and maintain a Drought Plan. We update these plans every five years.

Our Drought Plan sets out how we will manage our resources and supply system in dry years, to maintain our service to our customers.  


Defra gave us permission to publicly consult on this draft plan on 16 May 2018.


We have published a non-technical summary of the plan and a Statement of Response to feedback from stakeholders.

We also undertook a Strategic Environmental Assessment (SEA), a Water Framework Directive assessment and a Habitats Regulation Assessment (HRA) of our draft 2019 to 2024 Drought Plan to take environmental impacts into account.

To request copies of the Water Framework Directive and Habitats Regulation Assessment reports, contact the team by emailing futureconsultation@severntrent.co.uk.
